420:1.2083 Mould Steel properties

420 Tool Steel description

420 tool steel (1.2083) is a chrome-alloy, wear and corrosion-resistant plastic mould steel. Tool steel 420 can be characterised by its high chromium content, and how resistant it is to corrosion and acid, especially when hardened, tempered and polished. Due to these fantastic properties, the 420 (1.2083) plastic mould steel is an excellent choice for industries that require significantly better hygiene, such as medical and optical.

 

If you require to forge 420 tool steel, then you should heat slowly and uniformly until a temperature of 1000°C. After, take your steel and cool slowly in a furnace.

 

Hardening 420 involves preheating the steel to 600-700°C until it is heated. After, continue to heat until a temperature of 980-1050°C. It is essential to protect your 420 steel from decarburisation, which is achieved by using a salt bath, atmosphere furnace or vacuum. Finally, air cool or quench in oil.
