AN AUSTENITIC STEEL AND A STEEL PRODUCT

摘要

High-alloy austenitic stainless steels that are extra resistant to pitting and crevice corrosion in aggressive, chloride-containing solutions have a tendency for macro-segregation of Mo, at solidification of the melt. This problem is solved by an super austenite stainless steel having the following composition, in % by weight: max 0.03 C max 0.5 Si max 6 Mn 28-30 Cr 21-24 Ni 4-6 % (Mo + W/2), the content of W being max 0.7 0.5-1.1 N max 1.0 Cu balance iron and impurities at normal contents originating from the production of the steel.
