3. Metallographic organization.
The microstructure of 60Si2Mn steel plate after heat treatment should be tempered drontherite, and martensite and overburned structure should not appear. In addition, the grain size of the steel plate should not be less than grade 8.
Fourth, the delivery status.
60Si2Mn steel plates are usually delivered in quenched and tempered condition. During the quenching and tempering process, the temperature and time should be strictly controlled to guarantee the best mechanical properties. In addition, according to the user's requirements, other treatments can also be carried out on the steel plate, such as surface shot peening, polishing, etc.
In conclusion, 60si2mn steel plate is a high-quality alloy spring steel with a wide range of applications. Knowing its specification sheet helps to better select and use the material to meet the needs of different engineering fields.
