The most popular steel for induction hardening is 1045 steel heat treatment, which is closely followed by 4140. Alloy steels, cast irons, carbon steels, tool steels, and some 400 series stainless sheets of steel are examples of these materials. In either the normalized or hot forged state, 1045 carbon steel has good weldability, machinability, and high strength and impact qualities.
ASTM A516 Grade 65 is a weldable carbon steel of high grade that is suited for pressure vessels and boiler building. It is used in a variety of sectors, including the fertilizer industry, the aerospace industry, the nuclear power plant industry, the chemical industry, the oil and gas industry, the refineries industry, the petrochemical industry, and the paper industry.
What Is Steel Heat Treatment?
Heat treatment is the process of heating metal without allowing it to reach the molten (or melting) state and then cooling the metal in a controlled manner to choose desired mechanical qualities.
What Exactly Is Induction Hardening?
Induction hardening is a type of heat treatment in which a steel or cast iron item is heated using electromagnetic induction and then rapidly cooled (quenching). The metal undergoes martensitic transition after quenching, considerably increasing its hardness. It is a selective heat treatment that only heats the region that has to be hardened.
What Are the Advantages of Hardening Via Induction?
- Surface hardness, strength, and wear resistance have all been improved.
- The case is deep, with a tough core.
- After induction hardening, parts can be tempered to achieve the required hardness level.
- No masking is necessary during the selective hardening process.
- There is very little distortion.
- Allows for the use of low-cost steels like 1045.
- Often the most cost-effective treatment approach per pound.
Conclusion:
1045 carbon steel forging is commonly utilized in all industrial applications that require greater wear resistance and strength. Rocker arms, connecting rods, torsion arms, and other similar applications are common for 1045 carbon steel forgings.
