Properties and Applications

• Suitable for casting resin molds or large-sized plastic molds
• Excellent strength retention at temperatures
• Possessing high toughness
• High corrosion resistance
• Easily hardened and having little change of size
• Good thermal conductivity
• Capable for hardening of Nitriding
• Capability of tolerance for conditions of sudden temperature change
• Capable for heat ventilation by directly using water

Distribution Formats

• Heat Treatment (hardening and tempering) with hardness at 27-33 HRC

Hardening

• Hardening temperature at 840C-870C. Hardening substances used: water and oil. Hardness obtained after hardening at 52 HRC
• Annealing is required before hardening
• Nitriding temperature at 480C-560C. Hardness obtained after hardening at 600 HV
• Tempering temperature at 175C-220C. Hardness obtained after tempering at 48-52 HRC

Applications
