Common specifications of nm400 weathering steel
Steel materials NM400 weathering steel can be classified not only by chemical composition, main quality grade, main performance or use characteristics, but also by habit into carbon steel and alloy steel. Carbon structural steel is easy to smelt, has good processability, low price and large output, and can meet the requirements of common parts of general engineering structure in performance. Carbon structural steel NM400 weathering steel is usually rolled into steel plates and various sections, which are used for mechanical parts such as factory buildings and bridges.
The cold rolling precision bright pipe system produced by our factory has smooth appearance, uniform wall thickness, no oxide layer and high precision. The inner hole of NM400 weathering steel steel pipe can be divided into round, spline and plum blossom, which is widely used in automobile, motorcycle, electric power, petrochemical, ship, aerospace, bearing, pneumatic components, oil cylinder, boiler equipment, medical equipment, fitness equipment and other industries. Materials can be divided into: 10#, 20#, 35#, 45#, 40Cr, 16Mn, etc. According to the needs of users, we can make all kinds of national standard non-standard precision pipes. Special NM400 weathering steel materials and specifications can be ordered in advance.
Laser cutting, it is a specific way of cutting NM400 weathering steel steel plate cutting processing, is also one of the common way of cutting its on the cutting or machining parameters, if you want to get the right number, is that you can adjust these parameters to achieve a goal, adjust a few times more to get accurate numerical right in addition, we also need to know is, the faster the cutting NM400 weathering steel speed, the light intensity is smaller, so, the smaller the laser penetration is, in turn, can control the penetration depth of laser.
Vanadium mainly exists in the form of carbide in NM400 weathering steel 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%.
