The company is a leading company that sells steel plate products in the Central Plains region and has a high reputation in the steel plate industry Since its establishment, the company has always adhered to the business philosophy of "integrity cooperation and common development", and has sold steel products with various materials The products are widely used in petroleum, chemical, construction, boiler, decoration, offshore operations, electric heating, gravity machinery and other industries,A514 Gr Q quenched and tempered steel.
Q345R steel is common low alloy steel, which is commonly used for boiler and pressure vessel. The delivery status includes hot rolling or normalizing. Q345R steel yield strength is 265-345MPa, tensile strength is 510-640MPa, elongation is greater than 21%, and zero degree V-shaped impact energy is greater than 34J. Q345R steel standard is GB713. Q345R steel has good comprehensive mechanical and technological properties. The content of phosphorus and sulfur of Q345R steel is slightly lower than that of low alloy high strength steel plate.A514 Gr Q quenched and tempered steel
A514 Gr Q quenched and tempered steel,The main characteristics of A514 Gr Q quenched and tempered steel, 12Cr1MoV alloy steel plate are as follows:Compared with 12CrMoV steel, 12Cr1MoV alloy steel plate has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel is close to the stress rupture strength, and it has high plasticity under the condition of long-term tension. The process and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 ℃ before welding, and stress relief treatment is required after welding.
Quenching is a common heat treatment process. It is the metal heat treatment process in which the metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.
The tensile strength of A36 steel plate is 58-80 Ksi (about 400-550MPa), and the yield strength is 36 Ksi (about 250MPa); the tensile strength of Q235 steel plate is 370-500 MPa, and the yield strength is 235MPa; the tensile strength of SS400 steel plate is 400-510MPa, and the yield strength is 245MPa. For the mechanical properties of SS400 steel plate and Q235 steel plate, the thickness of steel plate is less than 16mm. It can be seen from the above data that ASME A36 and Chinese Q235 are named after the yield strength of the material, while SS400 is named after the tensile strength of the material.A514 Gr Q quenched and tempered steel
