Abstract
PURPOSE: In 18Cr-8Ni-Mo base austenite stainless steel, alloy components are adjusted so that ferrite phase is formed to cause two-phase structure, thereby enhancing toughness and weldability at extremely low temperature.
CONSTITUTION: An austenitic stainless steel contains, C<0.08%, Si<2.0%, Mn< 3.0%, Ni: 6 to 15%, Cr: 18 to 24%, Mn: 0.5 to 3.5%. In this composition, the content of ferrite-producing element Cr and Si relative to austenite-stabilizing element Ni is adjusted so that 3 to 30% of ferrite phase will form in austenite structure. Such structure drastically improves crack sensibility at welding, prevents embrittlement by inhibiting the precipitation of Cr carbide at heat affected zone of welding area. This further inhibits martensite modification at an extremely low temperature.
