3D printing powder for injection molds
TFM420 mold steel is a high-strength, high-wear-resistance stainless mold steel suitable for high-polish finishes.
It corresponds to S136, the European grade WNr. 1.2083, and the American grade AISI420J2.
This steel exhibits excellent corrosion resistance, superior polishability, excellent wear resistance, good machinability, and dimensional stability after heat treatment. BLS-4 is recommended for all molds, especially suitable for the following requirements:
- Corrosive injection molding materials such as PVC and acetates;
- Injection molding materials with high abrasion or containing additives (including thermosetting injection molds).
