Spot Supply 30crnimo8 Steel Plate Heat Treatment Process - China

common heat treatment processes for 30crnimo8 steel plates include quenching, tempering, etc.

##quenching

heating temperature: generally heated to 850-870℃.

within this temperature range, the structure of the 30crnimo8 steel plate can be fully austenitized, laying the foundation for subsequent good quenching structure.

housing time: the holding time needs to be determined according to the thickness and size of the steel plate.

cooling medium: oil is often used as a cooling medium.

##tempering

tempering temperature: the tempering temperature is usually between 550-650℃.

housing time: the tempering holding time is generally 1-3 hours.

for large-sized or thick-gauge steel plates, the holding time can be appropriately extended to 3-5 hours to ensure that the internal structure of the steel plate is fully tempered, eliminate quenching stress, stabilize the structure, and improve the comprehensive mechanical properties of the steel plate.

number of tempering times: generally, 30crnimo8 steel plates need to be tempered 2-3 times after quenching.

multiple tempering can eliminate stress more thoroughly, improve the uniformity of the structure, and further improve the performance stability of the steel plate.

in actual production, it is also necessary to appropriately adjust and optimize the heat treatment process parameters according to the specific use, performance requirements, and production equipment of the steel plate to obtain the best heat treatment effect.
