Experience and Capabilities of Heat Treatment Center

Covering almost all metal heat treatment methods to meet high-quality heat-treated parts demands.

Established in 1968, our company has a dedicated heat treatment center that ensures the integrity and timely delivery of the entire production process. With decades of scale expansion, mergers and acquisitions, our heat treatment center has become one of the most professional in the surrounding area. Through constant equipment and system updates, our heat treatment workshops operate digitally.

Our company has extensive experience in heat treatment and formulates different schemes based on the metal material properties, subsequent processing requirements, and application requirements of end customers. Our production range covers almost all metal heat treatment methods and can accommodate parts with a maximum diameter of 6800mm. Since 2006, we have expanded the proportion of plasma nitriding processes to meet customers’ higher requirements for heat-treated parts. Our state-of-the-art equipment allows us to quickly handle the heat treatment of individual or high-volume parts.

In addition to meeting our average bevel gear production needs, our heat treatment centers serve the global market. If you have any heat treatment requirements, please do not hesitate to contact us.

Normalizing is usually used to eliminate excessive stress inside gears, increase the toughness of parts, and improve the cutting performance of materials. Normalizing treatment is often used for gears made of alloy steel with a carbon content of 0.3% to 0.5%. The hardness of the normalized gear is HB163~217, and the strength and hardness are lower than that of the quenched or quenched and tempered gear. Therefore, for gears with low mechanical properties or large diameters, we usually use normalizing heat treatment

For gears made of high-quality carbon steel or alloy steel with a carbon content of 0.3% to 0.5%, quenching and tempering heat treatment are usually used. The hardness of the gear teeth is usually HB220-285. The smaller the gear size, the higher the hardness. The overall performance of the quenched and tempered gear is higher than that of the normalized bevel gear. The yield limit and impact toughness are about 40% higher, and the strength limit and area reduction are 5% to 6% higher (for carbon steel). So the tiny gears commonly used for quenching and tempering are matched with the normalized or quenched and tempered giant gears.

After surface hardening, the gear is tempered at a low temperature to reduce internal stress and brittleness. The tooth surface hardness is generally HRC45~55. The surface-hardened gear has a high load-bearing capacity and can withstand impact loads. The gear blanks that need to be quenched and heat-treated are first normalized or quenched and tempered so that the tooth center of the gear has a particular strength and toughness.

We usually use carburizing and quenching heat treatment for gears made of alloy steel with a carbon content of 0.10% to 0.25%. The tooth surface hardness is HRC58-63, and the teeth are ground after heat treatment to eliminate the deformation caused by the heat treatment. This type of gear has high contact strength and bending strength and can withstand greater impact loads. We are usually used for essential gear in heavy-duty vehicles, mining machinery, heavy industry machinery, etc.

We use the ion nitriding method to perform nitriding heat treatment on gears, because ion nitriding does not require a high temperature. The heat-treated gears can achieve high precision even without grinding teeth. Compared with the traditional heat treatment method, the gear after ion carburizing has better thermal hardness, fatigue strength, and corrosion resistance.
