Product Description
Specification of TP 304L 316L ASTM A312 Stainless Steel Welded Pipe: ASTM A312 is a standard for both welded and seamless pipes. Stainless steel contains chromium which provides the properties of corrosion resistance at high temperatures. Stainless steel can withstand corrosive or chemical environments due to its smooth surface. Stainless steel products are safe for long-term use with excellent resistance of corrosion fatigue.
