STAINLESS HOT COIL STRIP IMPROVING THE PICKLING RATE

摘要

The present invention is C: 0.001 ~ 0.5%, Si: 1.0% or less, Mn: 1.00% or less, Cr: 10.5-20%, Ni: 1.0% or less, N: 0.1% or less, 400 with other unavoidable impurities and Fe components The hot-rolled stainless steel sheet, wherein the hot-rolled steel sheet is subjected to annealing under a hydrogen atmosphere of less than a dew point of -10 ° C after hot rolling a material having the composition component, thereby improving the annealing rate by providing a porous surface scale. It is characterized by.;Dew point, hydrogen atmosphere, annealing furnace, sulfuric acid
