At the same time of doing well in S355ML specification 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 S355ML specification 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.
As an important classification of steel, S355ML specification hot rolled steel coil has the following advantages: first, hot rolled steel coil can be curled at will, reducing the occupied space, and it is convenient for transportation. Second, the processing of hot rolled steel coil is flexible and convenient. For spiral welded pipe, coil uncoiling, leveling, trimming, forming and welding are used. For longitudinal welded pipe, it must be formed and welded with steel plate. The hot rolled steel coil price is affected by the size and specification. The prices of different specifications and thickness S355ML specification, hot rolled steel coils are different.
Ordinary carbon structural steel S355ML specification has many impurities and low price. The ordinary carbon structural steel is used in places with low performance requirements and low strength, but it has good plasticity, toughness and cold deformation performance. High quality carbon structural steel has less harmful impurities, and its strength, plasticity and toughness are better than those of ordinary carbon structural steel. High quality carbon structural steel is mainly used to manufacture important mechanical parts.
The performance of heat treatment process reflects the difficulty of heat treatment and the tendency of defects of the steel. It mainly includes hardenability, superheat sensitivity, temper embrittlement tendency and oxidation decarburization tendency. The hardenability of S355ML specification, alloy steel is high. The cooling method can be used slowly during quenching, which can reduce the deformation and cracking tendency of the workpiece. The addition of Mn and Si will increase the superheat sensitivity of steel. The strengthening effect of alloy elements on steel in quenching and tempering state is the most significant.
The hardness of S355ML specification, wear-resistant steel plate is an important standard to measure wear resistance. The hardness of wear-resistant steel plate can be divided into microhardness and surface hardness. The microhardness of carbide in the wear-resistant layer of wear-resistant steel plate can reach over HVl700-2000, and the surface hardness can reach HRC58-62. Chromium alloy is the main wear-resistant layer of wear-resistant steel plate, and other alloy components such as manganese, molybdenum, niobium, nickel are added at the same time.
We have a professional production team and high-quality production equipment, and we also have a great S355ML specification advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the S355ML specification production of high-quality steel plates, steel pipes and other products that meet customer requirements.
The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel. It can provide customers with drawing design, S355ML specification deep processing services and installation solutions. 20 years of project experience has provided high-quality carbon steel, alloy steel products and high-quality after-sales service to customers in many countries around the world. The company has won widespread praise from customers.
