摘要
The present invention relates to a high strength austenitic precipitation hardening type steel having high tensile strength, short heat treatment time, low cost alloy composition design, and addition of Mo, which is effective for increasing corrosion resistance and strength, It is an object of the present invention to provide a method for manufacturing a stainless steel cold-rolled steel sheet.;The present invention relates to a method for producing a high strength austenitic precipitation hardening type stainless steel cold rolled steel sheet, which comprises, by weight%, C: 0.03 or less, Cr: 15-17%, Ni: 2.5-3.5%, Nb: 0.1-0.2% Hot-rolled steel slab containing not more than 4%, N: 0.05-0.15%, Mo: 0.3-1.0%, Si: not more than 0.5% and other unavoidable impurities and then annealed at 1200-1260C And subjected to cold rolling at a reduction ratio of 80% or more, annealing at a temperature between the martensite-austenite reverse transformation end temperature and the reverse transformation end temperature + 50C, followed by air cooling or water cooling The present invention relates to a method for producing a high strength austenitic precipitation hardening type stainless steel cold rolled steel sheet.
