Title: Production of alloyed hot dip galvanized steel sheet having excellent powdering resistance
Inventor: HIGUCHI YUKINOBU
IPC: C23C2/28
Filed: 1988-12-23
Abstract: PURPOSE:To improve the powdering resistance to pre-working and press working in the subject steel sheet by accelerating the heating speed at the time of alloying treatment and the cooling speed after the alloying treatment. CONSTITUTION:When the heating speed is accelerated, powdering resistance is improved and, at 10 deg.C/sec, it comes to the degree of not generating powdering by pressing or the like. As the cooling speed is accelerated, powdering resistance is improved and, at 15 deg.C/sec, powdering resistance for practical application is shown. Namely, though the effect improving of improving the powdering resistance by accelerating the heating speed at the time of alloying treatment or the cooling speed after the alloying treatment can be obtd. to the adequate degree even by single acceleration, superposed effect can be attained by further more combining the both. Thus, the steel sheet of which the hot dip galvanized steel is subjected to alloying treatment under the above conditions has the excellent powdering resistance to pre-working and press working.
