EN30B Steel

UK deliveries. Contact our well informed sales team. EN30B steel can be used for many purposes where toughness and high tensile strength are required. One of the main uses of EN30B is for plastic moulds, but it has may other applications for example: components of small presses including anvils, collars, strikers or hammers, rams or punch holders. Other applications include rivet snaps, air hardening cold chisels, crimping tools, clutch keys, racks, pinions and angle pins for pressure die casting tooling. Heat TreatmentFor best results, EN30B tools should be stress relieved, 610/630?C, prior to hardening. Hardening should be carried out by pre-heating at 300/400?C prior to raising the temperature uniformly to 830/850?C. When thoroughly soaked at this temperature either cool in air or oil quench. Tempering EN30B Tools should be tempered as soon as possible after hardening, preferably whilst still hand warm, by re-heating to the appropriate temperature as determined from the tempering curve, and soaking for at least 2 hours per inch of ruling section. Withdraw from the furnace and allow to cool slowly in air. Tempering EN30B between 275/450?C is not advised as it will seriously reduce the impact values obtained.
