Product Description

Alloy steel Plastic Mould Steel 1.2738 P20+Ni 718 Steel Round Bars

DIN 1.2738 is specially used for Plastic injection die moulds. The characteristics of a material are right sharpening, photo-etching properties with high purity and good homogeneity. DIN 2738 is upgraded version of plastic mold steel 0f 2311, which normally supply in Pre hardened condition. Hardness in as supplied condition 280-320 HB with having uniform hardness. The additional nickel content of 1 % increases through hardening. It has good machinability, suitable for Texturing, fine polishability, adequate corrosion resistance, vacuum-degassed steel.

1, Features

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;

2, Application

Used for various large -sized mirror plastic mould,percision mould;
a, Leather grain, pear skin grain etching, imitation stone moulds;
b, Clear plastic container classes such as pencil case, commodity high gloss mould;
c, Such as refrigerator, air conditioner production to demand higher large mould;

DIN 2738 is applicable for large & small plastic mould dies for Automotive Industries, Dies for Domestic goods , High finishing plastic Die, Boaster Plates of Presses, Die Holders & Shoe blocks for drop Hammers, Press Cassettes , Upsetter Blocker, forging dies, Different dies & mold for plastic products etc.
