Steel 1.2083 - RF
1.2083 - RF steel:
corrosive- and acid-resistant steel.
What?
1.2083 – RF steel is a high hardenable rust and acid-resistant steel. It is used in the manufacturing of smaller moulds or inserts for the plastics industry in the processing of duroplasts and thermoplasts, in which corrosive side-products can arise. RF is through-hardenable, is low in distortion, has a high wear resistance and compression strength. In tempered condition, RF is very highly polishable.
