AUSTENITIC STAINLESS STEEL SHEET EXCELLENT IN ACID PICKLING PROPERTY OF WORKED PRODUCT OF STAINLESS STEEL, AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an austenitic stainless steel sheet excellent in the acid pickling property of a worked product of stainless steel and to solve the problem of the conventional technology.;SOLUTION: The concentration of chromium in the surface layer part within 10 nm from the surface of the steel sheet is regulated to ≤11.5 mass% by setting at least either one of heating temperature of a slab, annealing temperature of a basis material sheet, and finish annealing temperature so that it takes a rather high value.;COPYRIGHT: (C)2001,JPO
