Hot Rolled Steel Round Bar 1.2738 Plastic Mold Steel For Injection Mold Base
1.2738 Mould Steel
1.2738 steel is a vacuum-melting chromium-nickel-molybdenum alloy
steel that has been hardened and tempered before it leaves the
factory. It offers the following advantages: No risk of quench
cracking and heat treatment; no need for heat treatment; shorten
the cycle time; Cost (for example, without overseas Chinese is
deformation); easy to amend the mold; nitriding and surface
hardening can be applied to improve the mold surface hardness and
wear resistance.
P20+NI steel is pre-hard mirror anti-acid plastic mould steel. The
steel pre-hardened, uniform material, high cleanliness, excellent
polishing performance and lithography. Also has high hardenability,
good electrical processing performance and striae processing
performance. Pre-hardened steel without quenching can also be used
for the mold bore, flange flame hardening can be implemented, the
hardness can be increased to 52HRC.
