42CrMo4 is a steel for quenching and tempering, which has a good combination of strength and toughness in the quenched and tempered condition. After the oil quenching, the steel will be through hardened up to ø60 mm bar diameter. The microstructure of larger dimensions is not fully martensite. The steel is applicable to induction hardening.

With Bozhong Group production experience, strict control 1.7225, DIN 42CrMo4, AISI 4142 chemical composition and 1.7225, DIN 42CrMo4, AISI 4142 mechanical properties.From casting, forging, steel to hot and cold rolling process, heat treatment, etc, we have the control of professional engineers.

Interrupted quenching of steels typically in a molten salt bath, at a temperature just above the martensitic phase. The purpose is to delay the cooling for a length of time to equalise the temperature throughout the piece. This will minimise distortion, cracking and residual stress.

Tempering ; AISI 4340 alloy steel should be in the heat treated or normalized and heat treated condition before tempering. The tempering temperature for depends upon the strength level desired. For strength levels in the 260 280 ksi range temper at 232°C (450 F). For strength in the 125 200 ksi range temper at 510°C (950 F).

1.7225 is a chromium molybdenum alloy steel specification widely used in the oil and gas industry. Similar to grade AISI 4130 but with a slightly higher carbon content. The higher carbon content of AISI 4140 gives greater strength and heat treatment capabilities in comparison to AISI 4130, however it does have inferior weldability characteristics.

AISI 4130 Steel Grade Heat Treatment; Annealing of 4130 steels; Annealing of 4130 steel forgings may be carried out by transferring the part straight from the forging operation to a furnace held at a suitable temperature, around 860º C (1575 º F) for annealing, holding for a suitable time then furnace cooling.

Furthermore, artificial neural networks will be used for the prediction of continuous cooling transformation diagrams, not only for specified strains but also for strain rates. Investigations of the CCT diagrams strain rate dependence for the tempering steel 42CrMo4 are also planned for the future.
