STAINLESS STEEL PIPES 304 manufacturer
Grade 304 is an austenitic Stainless Steel, also known as an "18/8" stainless Steel as it contains 18% chromium and 8% nickel. We manufacture all pipes are inspected/tested to the relevant standards including ASTM, ASME and API etc.The chromium content promotes the material's considerable resistance to the effects of corrosion and oxidation. The stainless steel alloy resists most oxidizing acids and will withstand ordinary rusting though this does not mean that the steel will not tarnish over time. The steel needs to be cold worked to generate higher tensile strength. For stainless steel sections which are welded heavily, post-weld annealing may be necessary to provide maximum corrosive resistance.
