The company has strict control on the quality of ASTM A573 welding structural steel. Each ASTM A573 welding structural steel is inspected for the whole process, including raw material purchase, production process according to the procedures and relevant regulations. According to the technical standards and technical requirements, the composite quality inspection is carried out to confirm whether the ASTM A573 welding structural steel meets the specified quality requirements. If the ASTM A573 welding structural steel does not meet the quality requirements, the non conformity control shall be implemented, and the unqualified ASTM A573 welding structural steel shall be removed, marked, registered and effectively isolated; the ASTM A573 welding structural steel shall be inspected and confirmed for acceptance, release and delivery, and the quality certificate shall be issued.
The main characteristics of ASTM A573 welding structural 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.
The purpose of ASTM A573 welding structural steel quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of ASTM A573 welding structural steel. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.
The company is mainly engaged in ASTM A573 welding structural steel steel plates manufacturing and deep processing, sales and distribution. It is committed to building a complete modern steel purchase and sale network. Here we would like to express our sincere gratitude to our old and new friends who have always given care, support, affirmation and help, and sincerely hope to establish a long-term cooperative relationship with them for mutual benefit, win-win and common development, and work ASTM A573 welding structural steel together for a better tomorrow.
From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%. We promise that every order will be tracked in a timely manner to ensure that customers can receive goods safely and constantly listen to their opinions and suggestions, reflect on our own problems, and let customers feel at ease. We have a large warehouse in Shanghai and Tianjin, which can provide customers with sufficient sources of supply.
