The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy A514 grade E alloy steel plate products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of A514 grade E alloy steel plate stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.
Q355NH material is a Chinese steel grade to GB/T 4171-2008 atmospheric corrosion resisting structural steel. There are five steel levels under Q355NH: Grade A, B, C, D, and E. Q355NH structural steel sheet is mainly used in vehicles, containers, construction, towers or other structural parts and other structures. It has good resistance to atmospheric corrosion. We supply A514 grade E alloy steel plate, Q355NH steel plates thickness less than 120mm.
Weathering steel plate is a kind of natural weathering steel plate with atmospheric corrosion resistance, characteristic corrosion and oxidation, which has been obtained in many fields. The common basic properties and the state of various weathering steel plates have been well reflected in the construction. At present, A514 grade E alloy steel plate it is mainly used for welding and manufacturing of traffic vehicles, construction machinery, bridges, towers, containers, steel containers and other low alloy structural steel. Features: strong toughness, rust resistance, corrosion resistance, thinning and consumption reduction, energy saving.
No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than A514 grade E alloy steel plate. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel A514 grade E alloy steel plate is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.
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. A514 grade E alloy steel plate, 13CrMo4-5 seamless pipe is used in petroleum, chemical industry, power station, boiler and so on industries.
