420M Steel

420M Steel

Steel name: 420M
Diagram No.: 2035
AISI/SAE designation: 420 mod.
Chemical composition in weight %: 0.35% C, 0.35% Si, 0.50% Mn, max. 0.0040% P, max. 0.006% S, 13.00% Cr, 0.50% Mo
Steel group: Plastic mould tool steels
Properties: No data
Applications: Finkl 420M is recommended for plastics, glass, and other. materials requiring molds exhibiting exellent polishability. The addition of the molybdenum improves the corrosion, resistance of 420M versus AISI 420. This may reduce or, eliminate the need to chrome plate molds in order to avoid, corrosion.
Reference: Not shown in this demo version.
