Hardness ASTME18 uptoSOHRC 50HRC 63HRC Relative Density4 ASTM B923 94.5% 94.5% 100% A2工具钢进行热处理可以提髙硬度和耐用性.因此建议对其进行热处理: 1.在标准(非真空)炉中将A2工具钢零件加热到970°C (1780° F),并保持30-40分钟; 2.将零件空气淬火至低于65°C(50 F); ...
Slowly heated A2 steel to 850-870 ℃(1562-1598°F) and allow enough times, let the steel to be thoroughly heated, Then cool slowly in the furnace at a rate of 4°C (40°F) per hour or less.. The A2 tool steel will get MAX 250 HB (Brinell hardness). Hardening of A2 tool steel...
1. A kind of air hardening tool steel.2. Good toughness with medium wear resistance and relatively easy to machine.Heat TreatmentAnnealing 800 to 850°C Slow controlled cooling in furnace at a rate of 10 to 20°C/hr down to approx. 600°C, further cooling in air. Hardness ...
This tool steel is used for cutting tools, rolls, shear blades, cold mandrels, cold stamping tools, moulds for plastics processing, blanking tools, punch dies, trim dies, forming dies, stamping dies etc Heat Treatment Soft annealing °CCoolingHardness HB ...
To anneal A2 tool steel for lowest hardness, heat slowly to 899°C(1650°F) and hold at this temperature for about two hours per inch of greatest cross-section. Cool steel A2 at a rate of 20°F (10°C) per hour to 650°C (1200°F) and reheat to 732°C (13...
Tool steel A2 can be double tempering, after intermediate cooling to room temperature. Temper at 200°C for a balance of hardness and strength or 350°C where strength is more important than hardness. A minimum holding time of 2 hours per inch of greatest cross-section should be used....

It increased hardness (64 HRC) as well as heterogeneity of the matrix as depicted by the micro-hardness profile, and decreased the toughness (3J) since coarse carbide networks are very hard and brittle. The austenitizing temperature as well as tempering temperature of heat treatment was found ...
P20 tool steels are nitrided or carburized. These steels are capable of being machined into complex and large dies and molds. P20 steels are mostly used in the carburized condition. The presence of chromium and nickel enhances the toughness and hardness of P20 steel...
