Description

Plastic mould steel pre-hardened to ****3 HRC. Uniform hardness distributed evenly in

large cross-sections. Excellent weldability with least hardness elevation.Good mirror

polishability and less streak texture making finish easier. Excellent toughness and nitriding

properties.

Applications

1)Pre-hardened status is easy for direct fabrication moulding.

2)Best suited for TVor washing machine housing

Mechanical Properties

Densified microstructure and uniform hardness. Vacuum degassing ensure low impurity

and dimensional stability and durable precision.Hardness is normally *2 HRC. No

hardening risks, no heat treatment, no distortion to tools. Can be further nitride or flame

hardened, locally. Heavier sections can be supplied pre-machined saving on weight and

less machining

Conventional smelt: EF+LF+VD

Delivery Condition

Hot rolled,Hot forged, hardened and tempered to HRC****3
