ASTM A269 Stainless Steel Welded Tube

Introduction of ASTM A269 stainless steel welded pipe

ASTM A269 standard covers seamless and welded austenitic steel. Due to its good chemical composition, ASTM A269 stainless steel welded tube is widely used in low or high temperature environment. In addition, ASTM A269 stainless steel pipe has excellent corrosion resistance, which can resist the erosion of various corrosive media.
