42CrMo4 STEEL GRADE

42CrMo4 is an engineering alloy steel containing chromium and molybdenum. It has high fatigue strength, abrasion and impact resistance, toughness, and torsional strength. It can be heat treated in a number of ways to give it a superior combination of properties. It is equivalent to SAE 4140 and En19 steel grades with minor differences in chemical ranges.

We can provide you 42CrMo4 in the following forms

About our Company

Testing and Packaging

Ambhe Ferro Metal Processors Private Limited is a well-known and reputed manufacturer of round bars in Maharashtra, India. Our factories are near the port of JNPT and the major consumption centres of Mumbai, Thane, Pune, Nasik, Ahmednagar, and Aurangabad.

Ambhe manufactures a wide range of round bars and other products as per customers’ demands. We keep in mind the quality parameters and requirements set by the industry. These round bars are known for their excellent features and quality. We manufacture high-quality bars as per domestic and global specifications as per customer requirements.

We use top-notch raw materials and systems to meet the customers’ needs.

Testing and packaging are considered one of the most critical steps of the manufacturing process.

We do several tests and inspections to check the quality of 42CrMo4 steel round bar. Tests done depend on the requirement of the users. Those quality tests can include chemical composition test, physical test, visual inspection, macro and micro test, NDT test and ultrasonic test depending on the requirement of the customers. We can also arrange third-party inspection if required. A test certificate is given for each consignment for the tests conducted.

At last, we bundle or pack the 42CrMo4 round bar to prevent damage at the time of transportation.

MATERIAL PROPERTIES OF 42CrMo4 FOR FABRICATION AND HEAT TREATMENT

Steel of Grade 42CrMo4 has the following properties

Machinability
42CrMo4 alloy steel has good machinability in the annealed condition.

Forming
42CrMo4 alloy steel has high ductility. It can be formed using conventional techniques in the annealed condition. It requires more pressure or force for forming because it is tougher than plain carbon steels.

Welding
42CrMo4 can be welded using all conventional techniques. However, the mechanical properties of this steel will be affected if it is welded in the heat treated condition, and post weld heat treatment should be performed.

Heat Treatment
42CrMo4 bars are heated at 845°C followed by quenching in oil. Before hardening, it can be normalized by heating at 913°C for a long period of time followed by air cooling.

Forging
42CrMo4 is forged at 926 to 1205°C.

Hot Working
42CrMo4 steel can be hot worked at 816 to 1038°C.

Cold Working
42CrMo4 alloy steel can be cold worked using conventional methods in the annealed condition.

Annealing
42CrMo4 steel is annealed at 872°C followed by slowly cooling in the furnace.

Tempering
42CrMo4 alloy steel can be tempered at 205 to 649°C depending upon the desired hardness level. The hardness of the steel can be increased if it has lower tempering temperature. For example, tensile strength of 225 ksi can be achieved by tempering at 316°C (600°F), and a tensile strength of 130 ksi can be achieved by tempering at 538°C (1000°F).

Hardening
42CrMo4 alloy steel can be hardened by cold working, or heating and quenching.
