316(L) Stainless Steel Sheet

Description:

Type 316 Stainless Steel is an austenitic chromium nickel stainless steel  containing molybdenum. This addition increases general corrosion resistance,  improves resistance to pitting from chloride ion solutions, and provides  increased strength at elevated temperatures. Properties are similar to those of  Type 304 except that this alloy is somewhat stronger at elevated temperatures.  Corrosion resistance is improved, particularly against sulfuric, hydrochloric,  acetic, formic and tartaric acids; acid sulfates and alkaline chlorides. Type  316L Stainless Steel is an extra-low carbon version of Type 316 that minimizes  harmful carbide precipitation in the heat affected zone during welding.

Specifications:

ASTM A240, A666

Typical Applications:

exhaust manifolds, furnace parts, heat exchangers, pharmaceutical and  photographic equipment, valve and pump trim, chemical equipment, digesters,  tanks, evaporators, pulp, paper and textile processing equipment, parts exposed  to marine atmospheres and tubing

Chemical Composition: ASTM A240, A666

Mechanical Properties: ASTM A240

Physical Properties:

Processing:

Types 316 and 316L are non-hardenable by heat treatment. Annealing: Heat to  1900 - 2100°F then rapidly quench Forming: Types 316 and 316L can be readily  formed and drawn.

Welding:

These alloys are generally considered to have poorer weldability than Types  304 and 304L. A major difference is the higher nickel content for these alloys  which requires slower arc welding speed and more care to avoid hot cracking.  When filler is needed, AWS E/ER 316L and 16-8-2 are most often specified.

Corrosion:

Types 316 and 316L Stainless Steels exhibit better corrosion resistance than  Type 304. They provide excellent pitting resistance and good resistance to most  chemicals involved in the paper, textile and photographic industries.
