HRC35-40 718H Steel CNC Machined Parts with ±0.01mm Precision and RA0.8 Surface Finish
718H steel is a pre-hardened mirror acid-proof plastic die steel with HRC35-40 hardness rating. This vacuum-fused el-molybdenum alloy steel offers exceptional wear resistance and dimensional stability.
- No risk of quenching cracks or heat treatment deformation
- Eliminates heat treatment costs and reduces mold production cycle
- Easy mold correction with capability for nitriding and surface hardening
- Uniform material distribution with high cleanliness and excellent polishing performance
- High hardenability with superior electrical and leather processing characteristics
