Engineering Machinery Cutting Plate Production—Heat Treatment Process

Heat treatment is the core process determining plate performance:

Quenching Process:

Heating temperature: 850-950°C (depending on material)

Soak time: 1-2 hours (per 25mm thickness)

Cooling medium: Oil quenching or polymer quenching bath

Cooling rate control: Critical rapid cooling in 650-500°C range

Tempering Process:

Temperature range: 350-550°C

Soak time: 1-3 hours

Hardness adjustment: Precisely controlled via tempering temperature

Special Heat Treatment Processes:

Surface hardening: Strengthening only the cutting edge

Carburizing: Enhancing surface hardness

Cryogenic treatment: Improving dimensional stability
