Abstract (en)
[origin: EP0601915A1] Alloy composition comprising, expressed by weight, - 42 to 49 % of nickel - 3.8 to 5 % of molybdenum - 19.5 to 22.5 % of chromium - 1.0 to 1.5 % of copper - less than 0.020 % of carbon - 1.5 to 2.5 % of titanium - 0.5 to 1 % of aluminium, - less than 0.1 % of manganese - less than 0.1 % of silicon - less than 0.010 % of sulphur - less than 0.020 % of phosphorus - the remainder consisting of iron and impurities. Process for conversion of an alloy of abovementioned composition; article made of such an alloy; and use of such an alloy in corrosion conditions under stress.
