718 Mould Steel
Equivalent grades: 3Cr2NiMo Mold Steel/P20+Ni Die Steel/HPM-Magic/PX4/PX5/2738 Tool Steel

718 is a prehardened mould steel, which offers the following benefits:
. No hardening risks
. No hardening costs
. Time saving (i.e., no waiting for heat treatment)
. Lower tool cost (e.g., no distortion to rectify)
. Modifications easily carried out
. Can be subsequently nitrided to increase surface
. wear resistance and locally flame hardened to reduce surface damage

718 is manufactured to consistently high quality standards with a very low sulphur content, giving a steel with the following characteristics:
. Good polishing and photo-etching properties
. Good machinability
. High purity and good homogeneity
. Uniform hardness
Note: Our 718 is 100% ultrasonic tested.

Heavier sections are supplied premachined, which offers the following advantages compared with unmachined
. Saving of weight
. Free of decarburised surface
. Exact nominal size (plus tolerance)
. Less machining
. Absence of scale minimises machine and tool wear
