316 Stainless Steel Pipe & Tube

What is 316 Stainless Steel Pipe & Tube?

316 Stainless Steel Pipe & Tube is a molybdenum-containing austenitic stainless steel piping product, upgraded from 304 series with enhanced corrosion resistance. It is widely used in environments containing chloride ions and weak corrosive media, bridging the gap between general and harsh corrosion scenarios.
