|

|
|
Stainless Steel 316L is a fully austenitic chromium \- nickel \- molybdenum steel. Molybdenum provides high corrosion
|
|||
|
|
resistance. Its very low carbon content also improves resistance to intergranular corrosion and enhances weldability.
|
|||
|
|
Post \- weld heat treatment i s generally unnecessary. Stainless Steel 316L is not susceptible to pitting or crevice corrosion
|
|||
|
|
in chloride \- rich solutions.
|
|||
|
|
Stainless Steel 316L is used to manufacture acid \- and corrosion \- resistant prototypes, as well as unique or series \-
|
|||
|
|
production parts,in sectors such as automotive, shipbuilding, aerospace, food and beverage (including corrosion \-
|
|||
|
|
resistant pipes and containers), chemical, pharmaceutical, oil, and gas.
|
|||
|
|
Parts made from stainless steel 316L can be machined, welded, shot \- peened, polished, and coated.
