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.
