SA588 Grade K chemistry Heavy Plate Available

45Mn carbon structural steel can obtain better comprehensive mechanical properties after quenching and tempering. The cutting performance is still good, but the welding performance is poor, the cold deformation plasticity is low, and there is a tendency to temper brittleness. It is generally used in the quenched and tempered state, and SA588 Grade K chemistry can also be used in Used in quenched and tempered or normalized state.The company has sufficient inventory and complete varieties and specifications. In line with the sales principle of low price operation and quality first, let customers buy SA588 Grade K chemistry at ease and use it comfortably! Integrity, professionalism and efficiency are our service tenets. We will wholeheartedly provide excellent SA588 Grade K chemistry products and high-quality services for new and old customers. We also sincerely welcome new and old customers to call and write to discuss business and guide work!No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than SA588 Grade K chemistry. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel SA588 Grade K chemistry is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.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 SA588 Grade K chemistry.The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
