High strength stainless steel having excellent intergranular corrosion cracking resistance and workability |
摘要 |
A high strength stainless steel having the composition in % by weight of C: not more than 0.04%, N: 0.04-0.20%, Si: not more than 1.0%, Mn: not more than 2.0%, Ni: 6.0-10.0%, Cr: 16.0-20.0% and balance Fe and impurities inevitably incidental from the steelmaking process, and that the composition is adjusted to have an A gamma value of 19-21, where: A gamma =(%Ni)+0.60 (%Cr)+0.7 (%Mn)+13 [(%C)+(%N)], is disclosed. The steel exhibit excellent intergranular corrosion cracking resistance and workability as well as high strength.
