Corrosion-resistant Plastic Mould Steel Flat Bar 1.2083 / 420
Introduction:
Grade 1.2083 / 420 / 4Cr13 die steel is the German brand Rooster special steel, plastic mould steel, the steel is stainless steel with high Cr content, containing more than 15% of Cr.
Grade 1.2083 / 420 / 4Cr13 has excellent abrasion resistance, acid proof and good polishing performance, good workability.
Grade 1.2083 / 420 / 4Cr13 steel has goodd mechanical processing performance. After heat treatment (quenching and tempering), it has excellent corrosion resistance, polishing performance, high strength and wear resistance.
