PROPRIETARY Chronifer M-4021 Heat Treatments

  • Forming. Warm: forging: 970 - 1100°C, slow cooling. Slow heating up to 830°C, then faster up to the forging temperature. Not recommended below 970°C. Cold: Relatively difficult. Feasible after anneal: 750 - 825 °C, slow cooling. Annealing. Soft anneal: 730 - 880°C, holding time 2 – 4 h, slow furnace cooling. Softening anneal: 650 - 750°C, air cooling. Intermediary anneal during cold deformation: 630 – 680°C Minimal cold reduction: = 10 - 15%, to avoid a too strong grain growth. Tempering: according to needs. Not recommended in the temperature range: 400 – 580°C. In this temperature range the precipitation of carbides at the grain boundaries may lead to brittleness and inter-granular corrosion. Quenching. Primary quenching, oil, air or gas quench: 980 – 1030°C. Option: Secondary quenching by subzero treatment: -20 à -80°C/12 - 48h, preferably -80°C/12 – 24h or cryo-quenching: -196°C/6 – 12h: progressive step-by-step cooling to avoid any possible cracking. The secondary sub-zero quenching should be made as soon as possible after the primary one. Tempering: according to needs. Not recommended in the temperature range: 400 – 580°C In this temperature range the precipitation of carbides at the grain boundaries may lead to brittleness and inter-granular corrosion.
