At the same time of doing well in A709 Gr 50 high strength steel production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the A709 Gr 50 high strength steel technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.
Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of A709 Gr 50 high strength steel service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.
15CrMo steel belongs to Pearlite Heat-resistant steel, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperature (generally not more than 600 ℃), and has certain hydrogen corrosion resistance. So A709 Gr 50 high strength steel, 15CrMo steel is widely used in petrochemical industry. However, due to the high content of Cr, C and other alloy elements in the steel, the hardening tendency of 15CrMo steel is obvious and the weldability is poor. The main problems are hardening in heat affected zone, cold cracks and reheat cracks during post weld heat treatment.
Compared with thick steel plates, A709 Gr 50 high strength steel, thin steel plates have many obvious advantages in steel plate processing and use. It is precisely these advantages of thin steel plates that make them more and more popular in various industries. First, compared to those thicker steel plate materials, thin steel plates are generally thinner in thickness. Thin steel plates themselves are lighter and thinner, and their weight is lighter, which is very convenient for handling during construction and transportation. It can save some storage and transportation space.
In steel standard JIS G3106, SM570 steel owned the highest yield strength above 460 Mpa, and the tensile strength within 570-720 Mpa. For SM570 steel, the C element content is 0.18%, the Si element content is 0.55% max, the Mn element content is 1.60% max, the P element content is 0.035% max, the S element content is 0.035% max. A709 Gr 50 high strength steel, SM570 steel with thickness from 6mm-300mm,width from 1500mm-4000mm,length from 5000-16000mm.
