A Heat treatment process of St52 steel plate

The heat treatment of A St52 steel plate is to change its organizational structure and properties by controlling the heating and cooling process of the material at a specific temperature. The following is the common heat treatment process of A St52 steel plate:

1. Normalizing: A St52 steel plate is heated to a suitable temperature range (usually 850-950°C), kept for a period of time and then quickly cooled to room temperature. This process helps to eliminate stress, improve hardness uniformity, and increase the strength and toughness of the material.

2. Tempering: First quench A St52 steel plate, then heat it to an area below the critical temperature, and cool it after holding it for a period of time. The purpose of tempering is to reduce the internal stress generated during quenching and improve the machinability and toughness of the material.

3. Quenching (Quenching) : Heating A St52 steel plate above the critical temperature (usually 860-900°C) and cooling rapidly. This process allows the material to cure quickly, forming a hard and brittle organizational structure, and improving the hardness and strength of the material.

Specific heat treatment parameters, such as temperature, holding time and cooling medium, vary according to specific material specifications and application requirements. Therefore, before conducting heat treatment of AST52 steel plate, it is recommended to refer to the relevant standards or consult A professional material engineer for accurate heat treatment guidance.
