Product Description

Product Description

 

ASTM A276 420/1.4108 X47Cr14 X65Cr14 Stainless Bearing Steel

1.4108 is a nitrogen-alloyed, high corrosion resistant martensitic steel with excessive toughness at hardness up to 60 HRC. Partly replacing carbon with nitrogen results in a much higher corrosion resistance and wear resistance compared to conventional, hardenable martensitic grades. In combining the Pressure Electro-Slag-Remelting-Process (PESR) with an elaborate forging technique, an extremely high purity level of a fine and homogeneous microstructure can be achieved. This implies excellent machinability, outstanding polishing and high dimensional stability after heat treatment. Consequently, 1.4108 is the ideal grade for bending-stressed or break-endangered medical instruments which are in contact with highly corrosive mediums.
