STAINLESS-STEEL PIPE WITH EXCELLENT SUITABILITY FOR SECONDARY PROCESSING FOR AUTOMOTIVE STRUCTURAL MEMBER |
摘要 |
A stainless-steel pipe which has a structure comprising ferrite or a combination of ferrite and martensite and which has a chemical composition comprising up to 0.20% carbon, up to 1.5% silicon, up to 2.0% manganese, 10 to 18% chromium, up to 0.03% nitrogen, at least one optional ingredient selected among up to 0.6% copper, up to 0.6% nickel, up to 2.5% molybdenum, up to 1.0% niobium, up to 1.0% titanium, and up to 1.0% vanadium, and iron and unavoidable impurities as the remainder. It has a TE, as defined by the equation TE = TS x (E1 + 21.9) [TS is the tensile strength in the pipe axis direction (MPa) and E1 is the elongation in the pipe axis direction (%)], of higher than 2,500 %.
