FERRITE TYPE HOT ROLLED STAINLESS STEEL SHEET HAVING EXCELLENT RESISTANCE TO SURFACE ROUGHENING AND TO HIGH TEMPERATURE FATIGUE AFTER WORKING

摘要

The present invention relates to a ferritic stainless steel hot-rolled steel sheet containing a predetermined amount of specific elements, and it is an object of the present invention to provide a hot-rolled steel sheet having good inner surface roughness and high-temperature fatigue properties after cold rolling and subsequent steps .;According to the present invention, since the annealing temperature range of the hot-rolled steel sheet is allowed in a wide range, it can be easily manufactured.
