Product Description
alloy steel grade 10.9 alloy steel grade 4140
Alloy steel 4140,hot rolled heat treated round bar
AISI 4140 SCM440 42CrMo Cold drawn steel bar steel shafts
CD 4140 / 4142 alloy bar's chromium content provides good hardness penetration, and the molybdenum imparts uniformity of hardness and high strength. This alloy responds well to heat treatment. In the annealed condition it machines at 110 sfm. It also has good wear resistance, toughness, and good ductility in the quenched and tempered condition. This grade can also be supplied as turned ground and polished for tighter dimensional tolerances for bearing fitting applications.
