Our company specializes in the production of steel plates, steel coil, steel sections, welded pipes and seamless pipes products, sales of GB, ASME, ASTM, JIS, DIN, EN, API and other standards and specifications of steel material S460ML for sale and deep-processed products, facing the domestic and foreign markets, welcome to call for inquiries. It is a modern high-tech professional enterprise integrating scientific research, production and sales.

The heat treatment hardness of DC53 mold steel is higher than that of SKD11, material S460ML for sale, the high temperature is 520-530 ℃, and the high hardness can reach 62-63HRC after tempering. In terms of strength and wear resistance, mold steel DC53 exceeds SKD11 mold steel. The toughness is twice that of SKD11 die steel. The toughness of DC53 is more prominent in cold work die steel. Tools made with DC53 rarely crack and crack, greatly increasing the service life.

Q345R steel plate is a special pressure vessel steel with a yield strength of 340 Mpa. material S460ML for sale, Q345R pressure vessel steel has good comprehensive mechanical and technological properties. The content of phosphorus and sulfur of Q345R pressure vessel steel is slightly lower than that of Q345 (16Mn) steel, and the tensile strength and elongation requirements of Q345R pressure vessel steel are higher than those of Q345 (16Mn) steel, and the impact toughness of Q345R pressure vessel steel is also required. Q345R pressure vessel steel is the most widely used Chinese pressure vessel steel.

At the initial stage of corrosion, the rust layer on the surface of weathering steel is denser than that of carbon steel, material S460ML for sale, and there are relatively few cracks and holes. After 25 days, delamination occurs in some parts of carbon steel and weathering steel, and there is no difference in corrosion products, mainly due to the role of alloy elements in the rust layer. The precipitation of Cu and Cr alloy elements in the weathering rust layer can resist the invasion of moisture and harmful ions in the atmosphere, and further corrosion of steel and base metal can be prevented, so as to achieve the effect of atmospheric corrosion resistance.

SA516Gr.70 steel chemical composition (%):C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45. ASME SA516Gr.70 material is a carbon steel grade for medium and low temperature pressure vessels. In order to meet the different requirements of users and facilitate production management, the S and P requirements of steel grades are divided into three levels of Ⅰ, Ⅱ and Ⅲ. material S460ML for sale, SA516Gr.70 pressure vessel steel is used to improve the notch toughness of welding steel plates for pressure vessels.

The high strength material S460ML for sale low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of material S460ML for sale ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
