Swiss Steel International THYROPLAST? 2083 Plastic Mold Steel
Categories: Metal; Ferrous Metal; Tool Steel; Mold Steel
Material Notes: To manufacture plastic parts, it is necessary to have steels with a high wear resistance, good polishability and etching ability, adequate corrosion resistance, and cost efficient machining properties. Employed for this purpose, as a function of the requirements are case hardening steels, quenched and tempered steels, corrosion-resistant steels, nitriding steels and maraging steels.
Corrosion resistant, good polishability. We recommend the use of vacuum-related THYROPLAST 2083 for the highest demands on polishability.
Applications
molds for processing plastics with corrosive action
Iron content calculated as remainder
Key Words: 1.2083, AISI 420
