BBN supply NM400 plate equivalent sheet material

In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product NM400 plate equivalent structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel NM400 plate equivalent supplier in the world.

The production process of hot-rolled steel plate and cold-rolled steel plate is different. Hot rolled steel plate is rolled at high temperature, and cold rolled steel plate is rolled at normal temperature. Generally speaking, cold rolled steel plate has better strength and hot rolled steel plate has better ductility. The thickness of NM400 plate equivalent cold rolling is generally smaller, and that of hot rolling can be larger. The surface quality, appearance and dimension accuracy of cold rolled steel plate are better than that of hot rolled steel plate.

The application of AR400 abrasion resistant steel plate: NM400 plate equivalent, AR400 abrasion resistant steel plate is mainly for wear exposed structures use, such as protective pads, shell walls for prospectors and bulldozers. AR400 abrasion resistant steel plate is also used to fabricate the supporting or reinforcing plate, the cutting plate for truck rollover, mixing elements and conveying elements, chute grooves, machine tools, crushers and shredders, waste briquetting presses, blades, paving abrasives and agricultural machinery.

The hot rolling method is to heat the NM400 plate equivalent steel material to about 1000 ℃ ~ 1250 ℃ and use the rolling mill to roll it. The traditional hot rolling process is generally divided into the following two steps: the first step is to use the primary rolling mill or billet rolling mill to roll the ingot, billet or continuous casting billet into a certain shape and size of billet. This kind of NM400 plate equivalent rolling process is usually called semi-finished product production, also called blank production.

S355J2G3 is low alloy high strength structural steel, and it is roughly equivalent to GB Q345D.S355J2G3 is a European standard steel with composition of C ≤ 0.20, Si ≤ 0.55, Mn ≤ 1.60, P ≤ 0.035, S ≤ 0.035. The meaning of J2G3 indicates that the delivery state of S355J2G3 steel is normalized, the impact energy at - 20 ℃ is 27J. G3 and G4 indicate the deoxidization mode. NM400 plate equivalent, S355J2G3 steel is semi killed steel, S355J2G4 steel is fully killed steel.
