  • EN30B is widely used for plastic moulds, but is also suitable for many other applications. The hardening treatment is relatively simple, quenching in air or oil from 810-830°C followed by tempering, with excellent mechanical properties being obtained. Owing to its strength this steel can be used for compression and transfer moulding as well as injection moulding and the relative freedom from distortion makes it superior to case hardening steels for complex mould applications. With limited availability of certain sizes in EN30B West Yorkshire Steel can also offer ‘high carbon’ EN30B to grade X45NiCrMo4. EN30B will machine readily in the annealed condition in which it is supplied.
  • Applications Typical applications and components include plastic moulds, blades, cutting tools, jaws and coining tools.

    Forging Heat the component slowly and uniformly to 1050°C. Re heat the X45NiCrMo4 as necessary and avoid working below a temperature of 850°C. After forging the steel cool slowly in furnace, thermoinsulating material.

    Annealing As this grade is supplied in the annealed and machineable condition re-annealing will only be necessary if the steel has been forged or hardened. Heat the steel uniformly to 630-650°C. Soak well then slowly cool in the furnace to approximately 600°C and then cool in air.

    Stress Relieving When dies produced in X45NiCrMo4 steel are heavily machined, it is recommended to stabilise just before finish machining in order to relieve machining strains. Heat to approximately 650°C soak well and allow to cool in air.

    Hardening Pre heat the steel slowly and uniformly to a temperature between 650-700°C and soak thoroughly. Continue heating the component to afinal hardening temperature of 840-870°C and allow the component to be heated through. Quench the steel in oil or cool in air.
