Wholesale price of S235JR carbon steel plate sheet matrial

S235JR carbon steel plate sheet,Q345B material is a low-carbon alloy steel (c <020%), with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability Q345R steel is a special plate for pressure vessels with a yield strength of 345MPa It has good comprehensive mechanical properties and technological performance In addition to the tensile strength and elongation requirements higher than Q345 (16Mn) steel, Q345R is also required to ensure impact toughness,S235JR carbon steel plate sheet.The company adheres to the external market, internal management, quality and efficiency oriented development path, and has achieved good economic and social benefits. With strong financial strength, advanced management experience, excellent sales service, strict quality management system and scientific overall marketing means, we will work hand in hand with you for common development. We are making all efforts working on the optimization of quality and price and best service for all our customers. No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than 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 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,S235JR carbon steel plate sheet.With the increase of carbon content in the steel material, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content is more than 0.23%, the welding performance of the steel material becomes worse. Therefore, the carbon content of low alloy structural steel used for welding is generally less than 0.20%. The high carbon content can also reduce the atmospheric corrosion resistance of steel material, and the high carbon steel in the open air is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of steel material.S235JR carbon steel plate sheetIn addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service. In the process of using our steel products, if there is any problem, just contact us in time, and our after-sales service personnel will look for countermeasures and solve the problem with you as soon as possible.S235JR carbon steel plate sheet
