High cleanliness excellent polishing performance Alloy Mould Block DIN1.2738/ASSAB 718H/AISI P20+NI
Product Introduction
718H 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.
718H 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.
Advantages/Features
Good polishing and photo-etching properties
Good machinability
High purity and good homogeneity
Uniform hardness
No hardening risks
No hardening costs
Time saving (i.e., no waiting for heat treatment)
Lower tool cost (e.g., no distortion to rectify)
Modifications easily carried out
Can be subsequently nitrided to increase surface wear resistance and locally flame hardened to reduce surface damage.
