Q355NH railway steel yield reached the leading level in China

The company specializes in the research and development, production and sales of Q355NH railway steel seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has Q355NH railway steel five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,Q355NH railway steel rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

Common grades of carbon structural steel plates: A36, A283Grade C, A572Grade 60, A573Grade 70, Q235B, Q235C, S235JR, S275J0, SS400, St37-2, Q355NH railway steel, St52-3. Our company can provide carbon structural steel plate thickness ranging from 6 to 300mm. These plates are widely used in various types of engineering structures such as steel structure buildings, construction machinery, heavy vehicles, bridges, pressure vessels. Besides, we can provide Q235B carbon steel plate with Z direction test.

Advantages of NM360 wear-resistant steel plate: NM360 steel has high strength: generally its yield strength is above 300MPa. 2. High toughness: The elongation is required to be 15% -20%, and the room temperature impact toughness is greater than 600kJ / m ~ 800kJ / m. For large welded components, high fracture toughness is also required. 3. NM360 steel plate has good welding performance and cold forming performance. 4. Low cold and brittle transition temperature.

Water cutting machine is called water knife for short, that is, water is used as knife. High pressure water jet cutting technology can perform any curve cutting process on any material, Q355NH railway steel included. The heat generated in the cutting process will be immediately taken away by the water jet without harm. Material, no need or easy to reprocess after cutting, safety and environmental protection, faster, faster, more efficient.

The outer diameter of the hot-rolled seamless pipe is generally larger than 32mm, and the wall thickness is 2.5-75mm. The diameter of the cold-rolled seamless pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of the thin-walled pipe can be 5mm, and the wall thickness is less than 0.25mm. The size accuracy of the cold-rolled seamless pipe is higher than that of the hot-rolled seamless pipe, Q355NH railway steel.

We are professional Q355NH railway steel carbon steel plates supplier with good reputation, and have participated many significant projects that finished with carbon steel materials in the world. If you have any question about carbon steel materials, such as A36 steel modulus of elasticity, A283 grade C properties, A572 grade 50 hardness, Q355NH railway steel EN 10025 S235JR equivalent Indian standard, S355JR specification, carbon steel price etc., please feel free to consult us.
