1.2550 Tool Steel

UK deliveries. Contact our well informed sales team. 1.2550 60WCrV7 is a high duty shock resisting alloy tool steel. In the hardened condition 1.2550 60WCrV7 is a heat resisting tool steel that combines great hardness with good toughness and shock resisting properties. Forging: Heat the 1.2550 tool steel component slowly and uniformly to 1000?C. Forge within a range of 1000/800?C, reheating if necessary. Cool slowly (preferably in a furnace) to avoid setting up stresses. Annealing: Heat the 1.2550 tool uniformly to 770?C, equalise, then furnace cool. Stress Relieving: If machining operations have been heavy or if the 1.2550 tool has an unbalanced section, remove stresses before hardening by heating up to 700?C, equalise, then cool slowly. Hardening: Pre heat the 1.2550 tool steel to 650?C and thoroughly soak. Continue heating to the final hardening temperature of 900/950?C. Allow sufficient time for the component to be heated through. Quench in oil. Martempering: Martempering is an alternative hardening procedure for 1.2550 which may be used when suitable salt bath equipment is available. Tempering: Heat uniformly and thoroughly at the selected tempering temperature and hold for at least one hour per inch of total thickness.
