316 Pipe
Product Descripition
What is 316 Pipe
Stainless Steel 316 Pipe is an austenitic stainless steel grade pipe that has good resistance to chloride ion corrosion stress cracking. Stainless steel 316 pipe has excellent forming and welding characteristics. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. Stainless steel 316 pipe also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections. The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures. Bestar Steel is a leading supplier and manufacturer of Stainless Steel 316 Pipe products in various scales and dimensions.
