M310 ISOPLAST Steel

M310 ISOPLAST Steel

Steel name: M310 ISOPLAST
Diagram No.: 2263
Mat.No. (Wr.Nr.) designation: ~1.2083
DIN designation: ~X42Cr13
AISI/SAE designation: ~420
JIS designation: ~SUS 420J2
Chemical composition in weight %: 0.38% C, 0.70% Si, 0.45% Mn, 14.25% Cr, 0.20% V
Steel group: Plastic mould steels
Properties: Advanced martensitic stainless chromium steel for plastic moulds.
Applications: Moulds for chemically aggresive plastics (e.g. PVC) and plastics containing abrasive fillers. Owing to its excellent polishability this grade is particularly suited for moulds of lenses and other kinds of optical products, such as spectacles, camera parts.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 1000 to 1050°C (1832 to 1922°F) / oil, air, gas Holding time after temperature equalization: 15 to 30 minutes.
Tempering: 100 to 250°C (212 to 482°F). Slow heating to tempering temperature immediately after hardening / time in furnace 1 hour for each 20 mm of workpiece thickness but at least 2 hours / cooling in air. For average hardness figures to be obtained please refer to the tempering chart.
Diagram note: Spezimen size: square 20 mm.
