4Cr13 / 420 / 1.2083 Plastic Mold Steel Flat Bar With Good Corrosion-resistant
4Cr13 / 420 / 1.2083 Plastic Mold Steel has good corrosion resistance and abrasion resistance, erosion resistance against common chemicals, especially P.V.C products, more effective, easy to reach the mirror light effect.
It's a special steel-plastic mold steel, it is high Cr-containing stainless steel, containing Cr up to 15% or more, has a very good wear resistance, anti-acid and good polishing performance, good machinability . After quenching more wear-resistant · Suitable for electric erosion suitable acidic plastic and require good polishing mold.
