Product Description
AISI 4140 / 42CrMoS4 / 1.7225 /EN19 Hot Rolled Metal Steel Round Bar
SCM440 ALLOY STEEL ROUND BAR
SCM440DIAMETER FROM 16MM TO 310MM
AISI 4140 SAE 4140 EN19 SCM440 42CRMO4 ALLOY STEEL ROUND BARS
SAE 4140 EN19 Steel is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. AISI 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness. The desirable properties of the AISI 4140 include superior toughness, good ductility and good wear resistance in the quenched and tempered condition.
