STEEL FOR BLADES AND METHOD FOR PRODUCING THE SAME |
| 摘要 |
An object of the present invention is to provide steel for blades with a significantly improved carbide concentration and a method for producing the same. The steel for blades has a metal composition consisting of, by mass, 0.55% to 0.8% C, not more than 1.0% Si, not more than 1.0% Mn, 12.0% to 14.0% Cr, and the balance of Fe with inevitable impurities, wherein the number of carbides in a ferrite structure of the steel for blades is 600 to 1,000 per an area of 100 μm2. |
