Diehl Steel’s 420 Stainless Steel’s High Hardness is Perfect for Mold Making

Diehl Steel’s 420 Stainless Steel’s High Hardness is Perfect for Mold Making

CINCINNATI, OH (April 3, 2014) – 420 stainless steel from Diehl Steel is a highly-refined mold quality steel that exhibits excellent polishability, good corrosion resistance and good wear resistance. 420 SS from Diehl is an electroslag remelt (ESR), giving it high internal cleanliness and homogeneity. Its high hardness makes it perfect for the manufacturing of plastic molds that require good parting line retention and sealing between colored resins.

Special melting and forging practices result in 420 having a ultra-high microcleanliness and a homogeneous microstructure. 420 stainless steel is used in a variety of applications such as ball bearings, gauges, shafts, cutlery, plastic mold cavities, and surgical and dental instruments.
