Production Name :
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.
− 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. It 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.
− T-316 is also available in Pump Shaft quality.
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.
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
hydrocloric and hydrofluoric acids. Excellent scale resistance at
temperatures up to 900˚C in continuous service and up to 850˚C for
intermittent service.
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.
