Analysis Of Heat Treatment Process Chinese Standard 25crmo Steel Plate - China

25crmo steel plate is a low alloy high strength steel widely used in aviation, automobile, machinery manufacturing and other fields.

its heat treatment process is crucial to improve the material properties.

the following is an analysis of the heat treatment process of 25crmo steel plate: 1 - purpose of heat treatment

improve strength: the tensile strength and yield strength of the material can be improved through proper heat treatment.

improve toughness: controlling the heat treatment process can enhance the toughness of the steel plate and reduce brittleness.

optimize hardness: through quenching and tempering, the required hardness level can be achieved to meet specific application requirements.

2 - heat treatment process steps

a.

**normalizing**

b.

**quenching**

c.

**tempering** 3 - selection of heat treatment parameters

- **heating temperature**: it needs to be selected according to the specific alloy composition and the required properties.

- **holding time**: it depends on the material thickness and the required uniformity.

- **cooling rate**: the selection of cooling rate during quenching is crucial to the final performance of the material.
