Undeformed O1 Steel Flat Bar Air Cooling Tempering For Measuring Tools
Undeformed Steel O1 Steel Flat Bar Used For Cutting Tools and Measuring Tools
SKS3 die steel known as "undeformed steel," but the formation of mesh carbide more sensitive.
It's mainly used for quenching and requires for small deformation, long and complex shape cutting tools and measuring tools and high-precision mold.
