AUSTENITIC STAINLESS STEEL HAVING IMPROVED PROCESSABILITY

AUSTENITIC STAINLESS STEEL HAVING IMPROVED PROCESSABILITY

Disclosed is an austenitic stainless steel with increased workability. The austenitic stainless steel includes, based on % by weight, silicon (Si): 0.1 to 0.65 %, manganese (Mn): 0.2 to 3.0 %, nickel (Ni): 6.5 to 10.0 %, chromium (Cr): 16.5 to 20.0 %, copper (Cu): 6.0 % or less (excluding 0), the su...

description Disclosed is an austenitic stainless steel with increased workability. The austenitic stainless steel includes, based on % by weight, silicon (Si): 0.1 to 0.65 %, manganese (Mn): 0.2 to 3.0 %, nickel (Ni): 6.5 to 10.0 %, chromium (Cr): 16.5 to 20.0 %, copper (Cu): 6.0 % or less (excluding 0), the sum of carbon (C) and nitrogen (N): 0.08 % or less (excluding 0), and the remainder being Fe and unavoidable impurities, wherein the austenitic stainless steel has a work hardening rate of 1500 MPa or less within a true strain range of 0.15 to 0.4. Therefore, when a sink bowl and the like are processed using the austenitic stainless steel, the true strain and work hardening rate of which are controlled, the occurrence of delayed fracture in a molded corner thereof, which has been subjected to a large amount of processing, can be prevented.
