1.2738/P20+Ni/3Cr2NiMo Pre-hardened Plastic Mould Block Steel
Pre-hardened large size injection mould, can be pollished normally. Used for making high demand large size plastic mould.
A, uniform hardness qualitative of Material;
B, No quenching crack danger,Without heat treatment costs that can reduce the tool cost;
C, Excellent polishing performance;
D, Good machining performance;
It has superior mirror polishing property,delivered in pre-hardened state and allowable for direct mold cutting without further heat treatment.Through distress annealing and surface nitrding treatment,the change in size and hardness are very slight.Typical applications include large plastic products such as electrical home appliances products,computers shell mould,telephone,speakers,PMMA products,etc.
