The company's operation is based on the principle of "quality for survival, reputation for development". In terms of management, we adhere to the principle of people-oriented, service-oriented and customer-oriented. All staff of the company have the courage to open up, unite and forge ahead, and work hard to grasp the good situation of global economic development, actively strengthen communication with outstanding enterprises in the A573 Grade 58 mild steel plate industry, keep pace with the times, and move towards a new course!
Some A573 Grade 58 mild steel plate, low-alloy high-strength steels have good atmospheric corrosion resistance. In some cases, appropriate precautions can be taken, and they can even be used without being coated in the atmosphere. The elements that improve atmospheric corrosion resistance are copper, phosphorus, silicon, chromium, nickel and molybdenum. The excellent atmospheric corrosion resistance of some low-alloy high-strength steels has led to the formation of new concepts in the design of buildings, bridges and other structures, that is, these structures are constructed with appropriate exposed components of low-alloy high-strength steel.
The alloy steel seamless pipe is a kind of product developed on the basis of traditional seamless steel pipe. Some characteristics of the A573 Grade 58 mild steel plate, alloy steel seamless pipe are also great progress and optimization based on the traditional seamless steel pipe products. Alloy steel seamless pipe is a kind of high performance seamless pipe. In industrial production, seamless pipe is usually used in pipeline engineering which needs to bear greater pressure.
Nickel element is mainly used to form and stabilize the austenite structure, so that the A573 Grade 58 mild steel plate steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.
13CrMo4-5 seamless pipe is a kind of pressure resistant seamless pipe in accordance with the European standard EN 10216-2. The chemical composition of 13CrMo4-5 seamless pipe is C 0.10-0.17, Si ≤ 0.35, Mn 0.40-0.70, P ≤ 0.025, S ≤ 0.020, Cr 0.70-1.15, Ni ≤ 0.30, Mo 0.40-0.60, Al ≤ 0.04, Cu ≤ 0.03. Mechanical properties of 13CrMo4-5 seamless pipe: tensile strength: 440-590 MPa, yield strength: ≥ 290 MPa, elongation: ≥ 22%, impact energy: ≥ 40J. A573 Grade 58 mild steel plate, 13CrMo4-5 seamless pipe is used in petroleum, chemical industry, power station, boiler and so on industries.
