China supplier offer JIS SM490B plates or sale

The effect of Q345B alloy steel plate on the mechanical properties in the annealed state. The strengthening effect of alloying elements on steel in the quenched and tempered state, because it fully utilizes all four strengthening mechanisms. Martensite is formed during quenching, and carbide is precipitated during tempering, resulting in a strong second-phase strengthening, and at the same time greatly improving the toughness. Therefore, obtaining martensite and tempering it is an economical and effective comprehensive strengthening method for steel such as JIS SM490B plates.

On Nov. 1st, 2019, BBN JIS SM490B plates steel organized Delegation to visit Zhengzhou Children Welfare Institute, and to give sponsorship as well as concerns to the Children. The handicapped children is always a pain topic. With the development of the society, they also gets increasing concerns and help from all walks of life. Thankfully, our Government also gives high concern to the handicapped children and has built JIS SM490B plates Children Welfare Institutes all over the country to guarantee their lives.

The company formulates appropriate JIS SM490B plates product internal control components, strictly controls the fluctuation range of chemical components, and ensures the stability of steel plate performance. Strengthen batching control and smelting operations, effectively control the content of harmful elements such as Sn, Sb, As, Cu, and reduce the content of P and S to improve the purity of steel, reduce the tendency of temper embrittlement, and improve the high temperature corrosion resistance of steel. It adopts controlled heating to ensure heating time and temperature, and measures such as controlled rolling to ensure the inherent quality of the steel plate.

What is the specific use of JIS SM490B plates, hot rolled plate in daily life? First of all, hot rolled plate is used in bridge, vehicle structure, frame and other fields to play a role of bearing pressure. Secondly, high pressure boiler vessels are also made of hot rolled plates, which can be heat-resistant and airtight, and can stably seal the hot gas in the container. Thirdly, stainless steel hot rolled plate can be used to process hardware products. It has excellent corrosion resistance, and is easy for processing.
