Standard Steel Grade (Steel Number) HBW in +S condition HBW in +A condition
EN 10088-3 42CrMoS4 (1.7227) ≤ 255 ≤ 241
HBW for +S: Depending on the chemical composition of the cast, and on the dimensions, particularly in the case of the +HH-grades, soft annealing may be necessary.

Heat Treatment

Quenching temperature: 820-880 °C (1500-1616°F), austenitizing period: at least 30 min (guide value), quenching agent: oil or water. The temperature at the lower end of the range is generally suitable for hardening in water, and the temperature at the upper end is suitable for hardening in oil.

Tempering temperature: 540-680 °C (1000-1255°F), tempering period: at least 60 min (guide value).

End quench test: 850 ± 5 °C.

Applications

Automotive and aircraft parts with high toughness, such as axles, shafts, gears, tyres, rods, crankshafts, screws, connecting and push rods, etc.
