Processing
Types 316 and 316L are non-hardenable by heat treatment. Annealing: Heat to 1900 - 2100°Fthen 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.
