What is the NM400 use for bridge price export to Romania

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 NM400 use for bridge industry, keep pace with the times, and move towards a new course!

The toughness index of Q345B steel should be tested by impact test at 20 ℃. Although the strength of Q345B steel and Q345A steel are the same, the S / P control of Q345B steel is more strict, and the ambient temperatures of NM400 use for bridge, Q345B steel and Q345A steel are different. The cold impact test refers to the impact test at a certain temperature to obtain the energy consumed by punching the specimen. The more energy consumed, the higher the toughness of the material. Q345A is not subject to impact test. So Q345B steel is better than Q345A steel.

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.

Modern steel-making steel purification facilities and advanced quality control methods have been perfected. Rolling steel can be produced according to controlled rolling and controlled cooling, normalizing, and quenching and tempering processes to produce σs 390-685Mpa series products. NM400 use for bridge, Low alloy high strength structural steel plate has stable quality, good wear resistance and low temperature toughness. It can be widely used in the manufacture of mining machinery, engineering machinery, high-rise buildings and heavy vehicles.

Mechanical Properties A588 corten steel:ASTM A588 Grade A is a high-strength, low-alloy steel plate utilized primarily in structural applications such as bridges and buildings. We stock this material as A588 Gr A & B in plate and 606 in sheet.Tensile: 70 ksi min (4” and under), 67 ksi min (4”-5”) 63 ksi min (over 5”-8”)Yield:50 ksi min (4” and under), 46 ksi min (4”-5”) 42 ksi min (over 5”-8”)Elongation:16% min in 8” 19% min in 2” (for plates wider than 24”)

Our company has its own steel plate manufacturing plant, processing plant and steel pipe plant. We can machine the steel according to the NM400 use for bridge customer's requirements and meet the customer's requirements. If you want to ask any questions about steel products, please contact us directly. Our customer service staff will give you a detailed answer. If you want to purchase NM400 use for bridge steel products, please tell me your specific needs, we have professional business personnel to communicate with you.

Our company will accept the product quality objection registration record, pass it to the NM400 use for bridge production unit and relevant departments, and timely coordinate the supervision of product NM400 use for bridge quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
