Steel pipe A572 Gr 65 CS steel carbon plate manufacturing, environmental protection equipment and other manufacturers supply steel products, which have been well received by new and old customers. Steel sales have maintained a strong growth momentum and have achieved a good reputation in the steel industry. The A572 Gr 65 CS steel carbon plate company has a young, energetic and service spirit, high-quality management team.
Generally, the production process of A572 Gr 65 CS steel carbon plate seamless steel tube can be divided into cold rolling and hot rolling. The production process of cold-rolled seamless steel tube is generally more complicated than that of hot rolling. The tube blank must be first rolled by three rolls, and then be subject to sizing test and cutting after extrusion. Then enter the annealing process. In appearance, the cold-rolled seamless steel tube is shorter than the hot-rolled seamless steel tube, and the wall thickness of the cold-rolled seamless steel tube is generally smaller than that of the hot-rolled seamless steel tube, but the surface looks brighter than the thick wall seamless steel tube, the surface is not too rough, and the diameter is not too much burr.
Tempering the important A572 Gr 65 CS steel carbon plate welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve A572 Gr 65 CS steel carbon plate strength, plasticity and toughness.
In the year of 2015, customer from Peru oil refinery contact with us from Internet. After one month's negotiation and quotation, they chose us as there supplier of raw steel plate A572 Gr 65 CS steel carbon plate grade ASTM A36. We get an trail order of 300 tons in April. When the first ship arrived, they inspect the steel plate and very happy with the quality we supply. Then they put another 1700 tons order, we sent to them within 90 days. Our company management group visit the customer in the beginning of 2016 and the visit is very successful.
