DESCRIPTION<\/span><\/b>\u00a0
Type 18 SR Stainless Steel provides excellent resistance to high-temperature scaling. 18SR is readily welded by conventional methods. It is not subject to embrittlement or loss of corrosion resistance in the heat-affected zones that affects many other straight chromium alloys. This alloy is especially valuable for applications requiring high-temperature scaling resistance superior to Types 409, 430 and 304 stainless steels and for those applications where Types 442 and 446 give only marginal protection.<\/span>\u00a0<\/span><\/p>\n
