The company initially focus on providing high-quality steel products to serve for China's rapid infrastructure development. Our company vision is to be the best service provider for iron & steel EN10025-4 S355M steel price products globally. To be an innovative business partner for our customers we aim to include sustainability in every aspect of our EN10025-4 S355M steel price business. We also provide third-party inspection and approval services and inventory management for our customers.

EN10025-2 S355JR low alloy steel grade is equivalent to GB Q345B in Chinese standard. For the normal thickness, these two steel grades are both owned 345MPa yield strength. Plate S355JR+N indicates that the S355JR steel plate must be done Normalized heat treatment when rolling for improve the steel strength and weldability. Our mill would roll EN10025-4 S355M steel price, S355JR alloy steel plate under as rolled or control rolled when customers' have not requested any heat treatment in their P/O.

EN10025-4 S355M steel price, Alloy plate is a steel plate with multiple uses because it has the following characteristics. First, better abrasion resistance. Alloy plate is more wear-resistant than ordinary steel plate. It does not scratch or wear, and has applications such as floor steel plate laying, steel plate wall and so on. Second, the alloy plate has higher strength. Third, the alloy plate is more resistant to high and low temperatures. Fourth, the alloy plate has outstanding corrosion resistance. As the steel laid on the ground, it must have good corrosion resistance. Because it will suffer from wind and rain for a long time, it must be very resistant, otherwise it will be damaged once it is corroded.

The microstructure of the quenched and tempered alloy steel, EN10025-4 S355M steel price after conventional heat treatment is tempered sorbite. For parts with wear-resistant surface (such as gears and spindles), induction heating surface quenching and low-temperature tempering are carried out, and the surface structure is tempered martensite. The surface hardness can reach 55HRC-58HRC. After quenching and tempering, the yield strength of quenched and tempered alloy steel is about 800MPa, the impact toughness is 800kJ / m2, and the core hardness is 22HRC - 25HRC. If the cross-section size is large but not quenched, the properties will be significantly reduced.

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. EN10025-4 S355M steel price, 13CrMo4-5 seamless pipe is used in petroleum, chemical industry, power station, boiler and so on industries.

The company adheres to the business philosophy of "good quality, customer first, honesty and trustworthiness", and strives to provide customers with high-quality EN10025-4 S355M steel price products and excellent services. Our company's products EN10025-4 S355M steel price are widely used in petroleum, chemical, power station, boiler and other industries, mainly used in reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear energy reactor pressure shells and other equipment.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
