Alloy Material Gb Ml30crmo Steel Heat Treatment Specification - China

GB ML30CrMo steel is an alloy steel widely used in mechanical manufacturing and engineering fields, and its heat treatment specifications are crucial to ensure material properties.

Heat treatment specifications: quenching 880℃, water or oil cooling; tempering 540℃, water or oil cooling.

The heat treatment process includes several key steps designed to optimize the hardness, toughness and wear resistance of the steel.

First, the steel needs to be preheated to eliminate internal stress and prepare the material for the next stage.

Typically, the preheating temperature is set between 300 and 400 degrees Celsius, and the duration depends on the thickness of the steel and specific requirements.

Next is the quenching stage, which is the core step of heat treatment.

Quenching is usually carried out in oil or water, and the temperature range is usually between 850 and 900 degrees Celsius.

This process can significantly increase the hardness and strength of the steel.

After quenching, the steel will become very brittle, so tempering is required.

The purpose of tempering is to reduce the brittleness of the material while maintaining its hardness.

Tempering temperature is usually between 500 and 600 degrees Celsius, and the duration can be adjusted as needed.

Through these precise heat treatment steps, GB ML30CrMo steel is able to achieve ideal mechanical properties and is suitable for manufacturing high-strength parts such as gears, shafts and bolts.

Understanding and following these specifications is essential to ensure the quality and performance of steel.
