Hot rolled 1500X6000mm size nm400 material specification

How to choose the NM400 material? Take 304 material as an example: From the perspective of price analysis, it is assumed that 304 stainless steel pipe is even lower than the general price of 301 material on the market and should be carefully identified. It is likely that other materials are fake. Confess whether the 304 stainless steel pipe is printed with 304 material on the surface and require the manufacturer’s quality certificate as a certificate; it can be tested with acid reagents.

Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, NM400 material quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the NM400 material International leading steel materials supplier.

TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the NM400 material steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.

After hot extrusion, the grains of the alloy wear-resistant steel plate are significantly refined, dendrites and network structures are broken, and the grain size and the distribution of precipitated phases in the alloy are more uniform to generate Al2Y and Al3Y phases distributed within and along the grain boundaries , The hardness is significantly improved, the mechanical properties are significantly improved, the deformation strengthening effect is more significant, and the corrosion resistance of the NM400 material, alloy wear-resistant steel plate is significantly improved.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
