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.
