The heat treatment knowledge of nm300 wear resistance sheet

After heating, a billet is refined for several passes of rolling, then edge cutting and straightening to become a nm300 wear resistance sheet steel plate, which is called hot rolling. Due to its high strength, good toughness, easy processing, good weldability and other excellent properties, hot rolled steel plate products are widely used in shipbuilding, automobile, bridge, construction, machinery, pressure vessel and other manufacturing industries.

The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our nm300 wear resistance sheet steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge nm300 wear resistance sheet steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.

Tempering the important nm300 wear resistance sheet welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve nm300 wear resistance sheet strength, plasticity and toughness.

The mechanical properties of nm300 wear resistance sheet, boiler pressure components steel include strength, plasticity, toughness and fatigue properties. Temperature has a great influence on the mechanical properties of steel. With the increase of temperature, the yield limit of all kinds of steel will monotonically decrease, but the tensile strength will rise to a high peak at a certain temperature, and then decrease.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
