What is the stock of Q345NQR2 chemistry in Malaysia

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, Q345NQR2 chemistry based on a high starting point and high technology, the company has vigorously developed various steel products Q345NQR2 chemistry and deep-processed parts, steel structures, precision castings, seamless pipes.

Cold rolled steel sheet has high strength, high hardness and high surface finish. It is generally thin steel plate and can be used as stamping steel plate. The strength of Q345NQR2 chemistry, hot rolled steel plate is relatively low, the surface quality can not match with that of cold rolled steel sheet. But its plasticity is good, and it is generally medium thick steel plate. The price difference between cold rolled steel sheet and hot rolled steel plate has a certain relationship with manufacturers. The quality of steel plate manufactured by different manufacturers is different, and the price is also biased.

Weathering steel plate for welding structure is made by adding metal materials such as chromium, molybdenum, titanium and vanadium to ordinary molten steel. The addition of these materials can form a protective film on the steel surface, which can resist weathering corrosion for a long time. The advantages of weathering steel plate for welding structure: It has very good welding performance and weather resistance, and is widely used in railways, bridges and other areas that need to be exposed to the atmosphere for a long time. Disadvantages of weathering steel plate for welded structure: It has very high requirements on the production process, and the poorer technology can not produce good weathering steel plate, Q345NQR2 chemistry.

Mg element can reduce the number, size, distribution and morphology of inclusions in steel such as Q345NQR2 chemistry. Micro Mg can improve the size and distribution of carbides in bearing steel. And the carbide particles of bearing steel containing magnesium are fine and uniform. When Mg content is 0.002% - 0.003%, the tensile strength and yield strength of the steel increase by more than 5%, and the plasticity remains basically unchanged.

Chemical composition of Q420 steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420 steel are: yield strength ≥ 340 MPa, tensile strength 500-680 MPa, elongation after fracture ≥ 18%, impact energy 34J. Q345NQR2 chemistry, Q420 steel has good mechanical properties and weldability, good cold and hot workability. Q420 steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts.
