Support for standard steel grades of structural alloy steel! SCM steel used as skin-rolled steel.
"SCM420H" is used as a case-hardened steel, similar to "SCM415H." By adding Mo to Cr steel, the mechanical properties are improved, and the mass effect is also reduced, making it applicable to relatively large parts. The main applications include general-purpose gears, shafts, and parts that prioritize strength and machinability. 【Features】 ■ Used as case-hardened steel ■ Improved mechanical properties ■ Reduced mass effect ■ Applicable to relatively large parts ■ Used in general-purpose gears, shafts, and parts that prioritize strength and machinability ■ Stock dimensions φ28 to φ230 *For more details, please refer to the catalog or feel free to contact us.
