BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of SA573 Grade 70 heat treatment steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main SA573 Grade 70 heat treatment production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.
Chinese grade of 20# steel plate: No.20American grade: ASTM1020Japanese grade: S20CGerman, British and French grades: C22, C20CMaterial No.: 1.0402, 1.0411Density: 7.85The strength of 20# steel plate is slightly higher than that of 15# steel plate, with little quenching and no tempering brittleness. SA573 Grade 70 heat treatment, 20# steel plate is generally used for bending and so on processing. The welding performance of arc welding and contact welding is good. When gas welding, the 20# steel plate with thin thickness and strict or complex shape is easy to crack.
The main characteristics of SA573 Grade 70 heat treatment, 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.
Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of SA573 Grade 70 heat treatment etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in SA573 Grade 70 heat treatment etc. steel is strictly controlled.
A588 Grade A steel plate is for high strength low alloy structural steel with 345Mpa minimum yield point to 100mm thickness."When propertly exposed to the atmosphere, A588 Grade A is suitable for many applications in the bare condition. SA573 Grade 70 heat treatment, A588 Grade Acould be produced in 200mm in our company.
As leading EN10025-6 S460QL structural steel plates supplier in China, our company has supplied hundreds of thousands tons S460QL steel plates to clients to assist them finish one after another SA573 Grade 70 heat treatment magnificent projects.
