Manufacturing method of martensite-based stainless steel for edged tools

摘要

There is provided a manufacturing method of martensite-based stainless steel for edged tools, which can decrease the number of passes during final cold rolling thereby to improve productivity. In the manufacturing method of martensite-based stainless steel for edged tools having a thickness of 0.1 mm or less by cold rolling, the final cold rolling is performed under condition of a diameter of a work roll of 100 to 130 mm, a cold rolling speed of more than 120 and not more than 200 m/min, and a lubricating oil viscosity of 30 to 40 mm²/s. Preferably, the cold rolling speed is 150 to 190 m/min, and the lubricating oil viscosity is 33 to 39 mm²/s.
