316/316L Stainless Steel Sheet, is a popular grade of stainless where superior corrosion resistance is of primary importance. 316 Stainless sheet is widely used in marine and highly acidic environments, underwater equipment, surgical tools, food and pharmaceutical applications. The addition of molybdenum increases the corrosion resistance of 316 Stainless over the more economical 304 grade.

PHYSICAL PROPERTIES
CORROSION RESISTANCE
Types 316 and 316L stainless steels exhibit improved chloride corrosion resistance when compared
to Type 304due to the molybdenum addition to the steel. This allows for acceptable corrosion protection
to marine atmospheres when pitting corrosion is concern. They also provide good chemical resistance
to most agents used in the paper, petroleum,food and dairy industries. They are useful in sulfuric acid
environments up to 150 °F (60 °C) when concentrations are below 5%.They show excellent corrosion
resistance to acetic, formic, phosphoric, and tartaric acids as well as some concentrations and temperatures
of bromide and lodide solutions. When welding operations are used, the lower carbon Type 316L allows for reduced
risk of intergranular corrosion caused by chromium carbide precipitation.
HEAT TREATMENT
Annealing: Heat to 1900 - 2100 °F (1038 - 1149 °C), then rapidly quench.
COLD WORKING
Due to the higher nickel content, these grades work harden at a lower rate than Type 304. In the annealed condition,
they exhibit excellent ductility and may be readily roll formed, deep drawn, and bent. Annealing is essential to restore
ductility and to lower hardness for subsequent forming operations.Severely formed parts should be annealed to remove stresses.
FORMABILITY
Types 316 and 316L can be readily formed and drawn using the same methods as used with Type 301 and Type 304. Although the forming
capability is very similar to Type 301, temperature variation will have less influence on material behavior. This product may become slightly magnetic when highly cold worked.
WELDABILITY
The austenitic class of stainless steels is generally considered to be weldable by the common fusion and resistance techniques. Special consideration is required to avoid weld "hot cracking" by assuring formation of ferrite in the weld deposit. These particular 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 a weld filler is needed, AWS E/ER 316L and 16-8-2 are most often specified. Type 316 and its low-carbon "L" version are well known in reference literature and more information can be obtained in the following references:
