PRODUCTION OF STAINLESS STEEL STRIP FOR BUILDING STRUCTURE
Document Type and Number:
Japanese Patent JP3839953
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To produce an inexpensive stainless steel strip for building structure excellent in corrosion resistance, weldability and weld zone characteristics in housing environment.
SOLUTION: Steel having a compsn. contg., by weight, 0.005 to 0.1% C, 0.05 to 1.5% Si, 0.05 to 1.5% Mn, ≤0.04% P, ≤0.05% S, ≤0.05% N, ≤0.1% (C+N), 8 to 17% Cr and 0.05 to 1% Ni, furthermore satisfying the conditions in the inequality of Cr(%)+Mo(%)+1.5Si(%)-Mn(%)-2Ni(%)-0.5Cu(%)-30C (%)-20N(%)≤12, and the balance Fe with inevitable impurities is heated at 1,100 to 1,250°C, hot rolling is finished at ≥800°C, it is coiled at ≥700°C, and the average cooling rate to a room temp. is regulated to ≤5°C/min.
