Product Description
Alloy steel bars  sae4140, scm440, 42CrMo4, 42CrMo, din 1.7225
This alloy responds well to heat treatment. Its chromium content provides good hardenss penetration, and the molybdenum imparts uniformity of hardness and high strength. In the annealed condition it machines at 110 sfm. Other desirable properties include good wear resistance, excellent toughness and good ductility in the quenched and tempered condition.
