High strength structural steel grades,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. , 13CrMo4-5 seamless pipe is used in petroleum, chemical industry, power station, boiler and so on industries.

High strength structural steel grades,The wear-resistant plate shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and high strength structural steel grades hardness is more than twice as that of the cast alloy with the same composition and hardness Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 15-25:1,high strength structural steel grades.

Both parties shall confirm the material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the steel plant.

The company has a perfect after-sales service system and quality assurance system. The company adheres to the service principle of "all for users", and has established a professional after-sales service team.
