At the same time of doing well in A572 Gr 60 CS steel carbon plate 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 A572 Gr 60 CS steel carbon plate 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.
Manganese steel plate is subdivided according to material grade: Q345A, Q345B, Q345C, Q345D, Q345E, A572 Gr 60 CS steel carbon plate. The main differences according to the classification are as follows: A needs no impact test, B needs room temperature impact test (20 degrees above zero), C needs zero degree impact test, D needs minus 20 degree impact test, and E needs minus 40 degree impact test. The most important characteristic of manganese steel plate is that under the condition of strong impact and extrusion, the surface layer rapidly hardens, but the core still maintains good toughness and plasticity, and the hardened layer has good wear resistance.
DIN 17102 TStE355 is mainly used for grain structure steel and normal rolling steel. Tste355 steel plate is a kind of grain structure steel. It is a standard rolled steel plate / sheet specially manufactured for different types of welding structures. It is made of basic materials, with high temperature resistance and low temperature resistance. Product A572 Gr 60 CS steel carbon plate is suitable for pressure boiler, mobile and vertical storage tank, high pressure pipeline, bridge, mast, cable, etc.
Medium and high carbon alloy hot rolled plates are mainly used in cold rolling and calendering, saw blades and tool industries. The company has taken advantage of smelting, hot rolled A572 Gr 60 CS steel carbon plate plate and coil finishing equipment and technical advantages, and has successfully developed a batch of high-carbon and its alloy steel and medium-carbon high-alloy A572 Gr 60 CS steel carbon plate steel hot-rolled coils with the goal of replacing imports. The iron oxide scale is delivered and trusted by high-end users.
