Basic requirements for nm450 plate impact resistance

The company has a group of experienced steel plate continuous processing line construction, production management, operation and professional and technical personnel. The company is a modern enterprise integrating scientific research and development, production processing, sales and service. Our main products include hot rolled plates, seamless pipes, NM450 plate impact resistance and steel structures. At the same time, it also adheres to international standards and adheres to the international line.

45Mn2 steel is added with manganese on the basis of No. 45 steel. After quenching and high temperature tempering, 45Mn2 steel can obtain high strength and good toughness, that is, it has good comprehensive mechanical properties, and is often used in manufacturing larger load shafts, connecting rods, fasteners, etc. The price of 45Mn2 steel is higher than that of No. 45 steel, NM450 plate impact resistance. And the performance of 45Mn2 steel after heat treatment is better. 45Mn2 steel can be used as parts under higher stress and wear conditions, such as universal joint shaft, axle, connecting rod cover, friction plate, etc. The performance of 45Mn2 steel after heat treatment is better than No. 45 steel and worse than 40Cr steel.

NM450 plate impact resistance, Q345 and Q345B are steel numbers. The differences are as follows:1. Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B.2. Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃).3. Q345 does not indicate carbon content of steel; Q345B carbon content is 0.20%.Q345 refers to carbon structural steel with yield point (σ s) of 345MPa. The following letters indicate the quality level, including A, B, C, D and E.

We are one of the largest weathering steel stock keepers in China and even in the world. For most specs weathering steel materials, we can arrange delivery within 5 days.
