Process compatibility
CNC machining
The second most used stainless steel after 304, the general purpose austenitic stainless steel 316 has superior corrosion resistance particularly in chloride containing environments and good elevated temperature strength. The low carbon version 316L has even better corrosion resistance in welded structures.
