Heat treatment performance of Hardox 450 wear-resistant steel plate for mining
Hardox 450 wear-resistant steel plate is an ideal material for mining and other heavy-duty applications that require superior material strength and resistance against abrasion, impact and structural fatigue. Its superior wear resistance makes it ideal for use in areas that are exposed to heavy abrasion, such as chutes, liners, conveyor systems and buckets.
In order to further improve the performance of Hardox 450 wear-resistant steel plate, heat treatment technology is used to further enhance its properties.
1.Annealing
Annealing is the process of heating a material at a certain temperature and then cooling it slowly. This process is often used to improve the toughness and ductility of Hardox 450 wear-resistant steel plate, especially when it has been subjected to cold deformation. The annealing temperature and cooling rate should be determined according to the strength grade and technique requirements of the steel.
2.Hardening
Hardening is the process of heating a material to an elevated temperature and then quenching it in order to increase its hardness and strength. The quenching temperature and cooling rate should be determined according to the strength grade and technique requirements of the steel. Usually, Hardox 450 wear-resistant steel plates are quenched at 780-840℃ and then cooled in water or oil.
3.Tempering
Tempering is the process of heating a material to a certain temperature and then cooling it in order to improve its toughness, ductility and machinability. Hardox 450 wear-resistant steel plate can be tempered in a temperature range of 150-630℃. The tempering temperature and cooling rate should be determined according to the strength grade and technique requirements of the steel.
4.Induction Hardening
Induction hardening is a form of heat treatment that uses an electrical current to induce localized heating of a material. It is often used to harden wear-resistant steel plates to improve their wear resistance and structural fatigue. The induction hardening temperature of Hardox 450 wear-resistant steel plate should be within 900-1150℃, and the cooling rate should be controlled below 50℃/s to ensure the stability of the treatment process.
In summary, Hardox 450 wear-resistant steel plate can be further improved with heat treatment technology. The annealing, hardening, tempering and induction hardening processes can be used to enhance its performance, including its wear resistance, bendability and weldability. These processes must be carried out in accordance with the strength grade and technique requirements of the steel in order to ensure the best heat treatment performance.
