Product Description
Finkl 420M is a martensitic stainless steel for plastic molds where high wear resistance and polishability are required in addition to corrosion resistance.

Finkl 420M is ALWAYS forged with a minimum of 5 to 1 reduction. It is sold in the annealed condition, with a hardness of approximately 200 on the Brinell scale, but may also be pre-hardened.

Finkl 420M stainless steel is forged utilizing wide die techniques which assure consolidated centers and fine grain structure, resulting in improved properties throughout.

Finkl 420M of Premium Quality is produced by the patented Double Vacuum Process, which consists of Vacuum Arc Degassing followed by Vacuum Arc Remelting. This process offers extraordinary cleanliness and a more unform distribution of alloys (see 420M Premium Quality Data Sheet).

Finkl 420M is 100% ultrasonically tested according tothe most rigorous standerds. It is fully warranted for a molds and dies.

The chemical composition of standerd 420 stainless has been modified in order to enhance corrosion performance.Molybdenum is added for carbide forming for improved strength, and improved corrosion resistance stabilizing element. The overall package is the best 420 type stainless steel availible.
