JIS SM400B plates alloy steel stock

Application of medium and thick plates: Medium and thick plates are used for construction engineering, machinery manufacturing, shipbuilding, bridge construction, etc. Medium and thick plates can also be used to manufacture various containers, furnace shells, furnace plates, some parts of tractors and welding components. Medium and thick plates are usually in form of bridges and automobile static steel plates, low alloy steel plates, shipbuilding steel plates, boiler steel plates, pressure vessel steel plates, checkered steel plates, automobile girder steel plates, etc.JIS SM400B plates,With high-quality steel and professional services, we have won international praise in infrastructure, shipbuilding, oil and other industries, and gradually grow into a bright star in the steel export industry, while winning unanimous praise from foreign customers It has laid a foundation for the development of our steel market and improved the control of steel plate production quality,JIS SM400B plates.JIS SM400B plates,In actual processing applications, the processing thickness of flame cutting ranges from 6 to 200 mm, and the cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting JIS SM400B plates with a certain thickness above 10mm.JIS SM400B plates,The effect of alloy elements of Q345B alloy steel plate on tempering transformation: improving the tempering stability. The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process. Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved.The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel.
