NM400 steel for vehicle cold bending performance

Based on the main business of iron and steel, we are committed to producing high-quality, green and efficient steel products. The main steel products are medium and NM400 steel for vehicle heavy plate, hot rolled coil, section steel, steel tube, etc., which are widely used in automobile, oil, railway, bridge, construction, electricity, transportation, machinery, shipbuilding and other important fields. Our steel products are exported NM400 steel for vehicle to Indonesia, Bangladesh, Myanmar, Iran, Brazil, Mexico, UAE, Iraq, etc Egypt, Mozambique, Ukraine and other dozens of countries and regions.

Q345R steel is common low alloy steel, which is commonly used for boiler and pressure vessel. The delivery status includes hot rolling or normalizing. Q345R steel yield strength is 265-345MPa, tensile strength is 510-640MPa, elongation is greater than 21%, and zero degree V-shaped impact energy is greater than 34J. Q345R steel standard is GB713. Q345R steel has good comprehensive mechanical and technological properties. The content of NM400 steel for vehicle phosphorus and sulfur of Q345R steel is slightly lower than that of low alloy high strength steel plate.

NM400 steel for vehicle, 20CrMo alloy steel plate has high hardenability, no temper brittleness, good weldability, little tendency of cold cracking, good machinability and cold strain plasticity. 20CrMo alloy steel plate is generally used in the state of quenching and tempering or carburizing and quenching. 20CrMo alloy steel plate is used to manufacture high-pressure pipes, fasteners and carburized parts, such as gears and shafts, working in non corrosive medium and medium containing mixture of nitrogen and hydrogen under 250 ℃.

Ultrasonic flaw detection emits ultrasonic waves to the NM400 steel for vehicle steel plate under inspection. If there are defects in the steel plate, the ultrasonic waves will reflect, refract or deform waveforms due to the defects. By recording these changes, the type and shape of the defects are analyzed. Due to its high energy and good penetration performance, and the smoothness of the NM400 steel for vehicle steel plate itself, ultrasound is often used to detect defects such as inclusions, shrinkage holes, bubbles, and cracks in the steel plate.

NM400 steel for vehicle, SA36 steel plate is one of our main product, it is belong to the carbon and low alloy high strength steel plate. We can supply the different sizes of SA36 steel plate. And the rolling size of SA36 steel plate is following: the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the SA36 steel coil thickness should not exceed 25 mm.
