Production Name :

 

T-316 Pump Shaft Quality (PSQ) 

 

Stainless Steel
17-4PH, T-630 
 
Characteristics
− 17-4PH offers a unique combination of properties: high strength, excellent corrosion resistance, good fatigue strength, superior resistance to galling and seizing, easily heat treated by a short, simple low temperature treatment with minimal distortion and no scaling. Parts may be finish-machined before hardening. It has good fabrication characteristics and is easily weldable.
− T-630 is usually supplied in Condition 'A', commonly called solution treated, but it should be noted that it can be as hard as HB363, and is frequently HB 321/341. Also the steel should never be put into service in Condition'A' - the structure is untempered martensite, with low ductility and poor resistance to stress cracking.
− See the Data Section for machinability ratings of Condition A and Condition H1150.
Typical Applications
− Pump shafts, oil well valves, valve stems and bushings. Aircraft and missile fittings and components, marine propeller shafts and blades, pulp and paper mill equipment, orifice plates, chemical processing equipment, torsion bars, corrosion resistant gears.
Corrosion and Heat Resistance
− The corrosion resistance is comparable to T-302/304 in most environments - a wide variety of conditions in the petroleum, chemical, pulp and paper, dairy and food processing industries. May be used in service temperature up to 400°C. 

 

 

Stainless Steel T-416 Pump Shaft Quality (PSQ) 
 
Characteristics
− T-416 is quite simply described as a free-machining modification of T- 410. The addition of phosphorus and sulphur is responsible for improved machinability, but results in some disadvantages such as lower impact values and poor weldability. However, the steel is designed for free- machining and it is the best of all the stainless steels. The rating is as high as 90% - 160 surface feet per minute.
− T-416 is mainly supplied in the annealed condition; but it responds to conventional heat treatment and a wide range of mechanical properties may be obtained. It is magnetic in all conditions.
Typical Applications
− T-416 is used in all appIications demanding the mechanical properties and corrosion resistance of T-410 - plus the free machining. Pump shafts, pistons, valves, automatic screw machined parts, nuts, bolts, studs.
Corrosion and Heat Resistance
− Maximum resistance is obtained by hardened material, ground and polished. Excellent resistance to fresh water, mild alkalis and acids, dry atmospheres, neutral and basic salts. Fair resistance to scaling up to 675˚C in continuous service.
Mechanical Properties

Characteristics
− In simple terms, T-316 is a molybdenum bearing T-304; the addition of molybdenum greatly increases its corrosion resistance and its mechanical properties at elevated temperatures. This combination of corrosion resistance and high creep and tensile strength, plus good cold forming and drawing properties makesT-316 suitable for a very wide range of applications.
− T-316L is a a low-carbon modification which minimizes carbide precipitation during welding and exposure to elevated temperatures in the 425˚C/815˚C range. lt can be used in the as-welded condition. T-316N has a higher nitrogen content than T-316 to increase strength with minimum effect on ductility and corrosion resistance.
− T-316 is non-magnetic in the annealed condition and cannot be hardened by thermal treatment, but it does work harden. Machinability is approximately 42% - 70 surface feet per minute.
Typical Applications
− Widely used in the pulp and paper, chemical, petro-chemical, Fertilizer and pharmaceutical industries. Heat exchangers, marine applications, aircraft industry, fittings, architectural components. Pump Shafts.
Corrosion and Heat Resistance
− T-316 is more resistant to corrosive conditions than any of the more commonly used stainless grades (but see T-317). Very good resistance to the sulphur compounds used in pulp and paper processing. Good resistance to sulphuric, sulphurous and phosphoric acids and salts, also hydrogen sulphide; but poor resistance to hydrochloric and hydrofluoric acids. Excellent scale resistance at temperatures up to 900˚C in continuous service, and up to 850˚C for intermittent service.
Mechanical Properties
− 75,000 psi minimum tensile strength
− 30,000 psi minimum yield
− 35% minimum elongation (in 2")
− 50% minimum reduction of area (R/A)

− T-416 is also available in Pump Shaft quality.
Typical Applications
− T-416 is used in all applications demanding the mechanical properties and corrosion resistance of T-410 - plus the free-machining. Pump shafts, pistons, valves, automatic screw machined parts, nuts, bolts, studs.
Corrosion and Heat Resistance
− Maximum resistance is obtained by hardened material, ground and polished. Excellent resistance to fresh water, mild alkalis and acids, dry atmospheres, neutral and basic salts. Fair resistance to scaling up to 675˚C in continuous service.
Heat Treatment
− Annealing - Heat to 850˚/900˚C for 30 minutes per inch of section thickness. Cool slowly in furnace.
− Hardening - Heat to 950˚/1000˚C and quench large sections in oil. Small sections may be quenched in air.
− Tempering - According to mechanical properties required, but the range of 400˚/580˚C is not recommended.
 
Characteristics
− T-410 is the basic chromium grade in the '400' series. It can be treated by conventional means to develop high strength properties with good ductility. In fact, it is in the heat treated condition that T-410 develops its maximum corrosion resistance, particularly when ground and polished. And when heat treated to HRC 18/22, with double tempering, per NACE MR01-75, resists corrosion in severe sour gas environments. Excellent for highly stressed parts needing moderate heat and corrosion resistance with high strength.
− T-410S limits the carbon content to .08% max for better weldability,mainly in sheet and plate.
− T-410 is magnetic in all conditions. It has better machining characteristics than the chromium-nickel grades and is rated at 54% - 90 surface feet per minute.
Typical Applications
− Machine parts, pump shafts, blast joints, blow-out preventers, pistons, valve parts, bolts, bushings, jet engine parts, rifle barrels, hardware, cutlery
Corrosion and Heat Resistance

Heat Treatment
− Annealing - Heat to 850˚/900˚C for 30 min. per inch of section thickness and slow cool.
− Hardening - Heat to 950˚/1000˚C and quench in oil, water or air according to section and properties required.
− Tempering - According to properties required, but the range 400˚/580˚C should be avoided due to low impact values which result at these temperatures. Double tempered at 660˚/640˚C for SSC resistance.
 
 
 
Stainless Steel T-316, T-316L, T-316N
(UNS S31600, S31603, S31653)
- 18-12-3 Chromium-Nickel-Molybdenum austenitic stainless steel.
- Available in most forms & sheets, plates and coils to ASTM A240; bar sections to ASTM A276 & A479 
 
Characteristics
− Essentially similar to T-316; but the increased chromium, nickel and molybdenum content results in better corrosion resistance, higher tensile strength and higher creep strength than T-316.
− T-317L with .03% maximum carbon content is used to restrict carbide precipitation during welding and in applications where maximum corrosion resistance is required. In fact, for small quantities, T-317 is frequently available only as T-317L.
− T-317 is non-magnetic in the annealed condition and is non-hardenable by heat treatment. Machinability is 39% - 65 surface feet per minute.
Typical Applications
− Pulp and paper, chemical and pharmaceutical processing equipment and machinery.
Corrosion and Heat Resistance
− Significantly better corrosion resistance that T-316 in the same environments. Good oxidation resistance in continuous service to 925˚C and in intermitent service to 879˚C.
 
Characteristics
− In simple terms, T-316 is a molybdenum bearing T-304; the addition of molybdenum greatly increases its corrosion resistance and its mechanical properties at elevated temperatures. This combination of corrosion resistance and high creep and tensile strength, plus good cold forming and drawing properties makes T-316 suitable for a very wide range of applications.

Stainless Steel T-304, T-304H, T-304L
(UNS S30400, S30409, S30403)
 
Stainless Steel
T-310, T-310S 
 
Characteristics
− These are austenitic chromium-nickel stainless steels with excellent oxidation resistance and capable of resisting temperatures up to 1150˚C in continuous service. They also provide good resistance to carburizing environments. T-310S is simply a low carbon modification which is to be preferred in welded construction.
Typical Applications
− Furnace parts, carburizing boxes, heat treating trays, oven linings, heat exchangers, gas turbine parts, jet engine rings.
Corrosion and Heat Resistance
− Primarily designed for heat resistance, T-310/T-310S are good to 1150˚C for continuous service and offer resistance to 1038˚C for intermittent service. They provide good resistance to thermal fatigue and cyclic heating. Excellent corrosion resistance at normal temperatures, with good resistance to carburizing and reducing environments at high temperatures.
Mechanical Properties
− Typical – at Room Temperature
− Tensile Strength – 95,000 psi (655 N/mm2)
− Yield Strength – 45,000 psi (310 N/mm2)
− Elongation – 50%
− Hardness – Rb 179 (89)
 
 
Characteristics
− Perhaps the most versatile and widely used general purpose austenitic stainless steel. It is excellent for forming, drawing and welding, and provides good corrosion resistance without post-weld annealing. The extra low carbon analysis of T-304L, which further restricts carbide precipitation during welding permits the use of this steel in corrosive service in the as-welded condition. T-304L is essential particularly where heavier sections are involved. T-304H is a modification with .04/.10 carbon and no nitrogen content. The mechanical test requirements are the same as T-304 but the 'H' type is not normally subject to intergranular corrosion testing. T-304 cannot be hardened by thermal treatment but it does work harden. It is non-magnetic when annealed. Machinability is approximately 45% - 75 surface feet per minute
Typical Applications
− These grades are used extensively in the dairy, beverage, brewing, wine and food industries where the highest degree of cleanliness is of prime importance. Chemical equipment and storage tanks, cryogenic vessels, sinks, saucepans and kitchen equipment, architectural trim, petroleum refinery equipment
Corrosion and Heat Resistance
− T-304 is highly resistant to strong oxidizing acids, such as nitric acid, and resists many organic and inorganic chemicals. Excellent for hot petroleum products. It has good scale resistance up to 900˚C in continuous service and 843˚C for intermittent service. T-304L would be equal and generally superior.
