What is the BBNSteel Q235NH steel plate for construction machinery application

The company adheres to the Q235NH steel plate for construction machinery external market, internal management, quality and efficiency oriented development path, and has achieved good economic and social benefits. With strong financial strength, advanced management experience, excellent sales service, strict quality management system and scientific overall marketing means, we will work hand in hand with you for common development. We are making all efforts working on the optimization of Q235NH steel plate for construction machinery quality and price and best service for all our customers.

SAPH series steel plates for automobile structures have good stamping and forming properties, and are used to make automobile beams, wheels and other structural parts. Hot rolled high yield strength steel for cold forming has high strength and good cold formability, and is used to make structural parts such as automobile beams. Q235NH steel plate for construction machinery, The steel for automobile girder has good stamping forming performance, and is used for manufacturing structural members such as longitudinal beams and transverse beams of automobile frames.

Bridge steel plate is specially used for erecting railway or highway bridges. Q235NH steel plate for construction machinery, bridge steel plate is required to have high strength and toughness to bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The bridge steel plate used for bolt welding bridge should also have good welding performance and low notch sensitivity.

Vanadium mainly exists in the form of carbide in Q235NH steel plate for construction machinery and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.

Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with Q235NH steel plate for construction machinery, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.

We are professional Q235NH steel plate for construction machinery carbon steel plates supplier with good reputation, and have participated many significant projects that finished with carbon steel materials in the world.
