Where the nm300 plate chemical composition is used

The characteristic of niobium in nm300 plate chemical composition etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.

The influence of thermal physical properties and mechanical properties of composite wear-resistant steel plate on laser bending is complex, which mainly involves the thermal expansion coefficient, specific heat capacity coefficient, thermal diffusion coefficient, yield limit, elastic modulus and hardening index. Under the same process conditions, the greater the specific heat and thermal conductivity of the composite nm300 plate chemical composition, wear-resistant steel plate, the less obvious the temperature gradient in the forming process, and the smaller the bending angle produced.

Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.
