Common specifications of nm400 material

The company has superior geographical location and convenient transportation. After more than 20 years of market trials and tribulations, from small to large, from weak to strong, in order to meet the needs of customer extension development, the company expanded the deep NM400 material processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and NM400 material steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.

After heating, a billet is refined for several passes of rolling, then edge cutting and straightening to become a NM400 material steel plate, which is called hot rolling. Due to its high strength, good toughness, easy processing, good weldability and other excellent properties, hot rolled steel plate products are widely used in shipbuilding, automobile, bridge, construction, machinery, pressure vessel and other manufacturing industries.

There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products NM400 material are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.

Laser cutting, it is a specific way of cutting NM400 material 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 material speed, the light intensity is smaller, so, the smaller the laser penetration is, in turn, can control the penetration depth of laser.

Difference between Q235A steel and Q235B steel plates: in the national standard GB700, the difference between NM400 material, Q235A steel and Q235B steel plates is mainly in the carbon content. In addition, Q235A steel plate does not do impact test, while Q235B Q235B steel plates need normal temperature impact test, V-notch. Relatively speaking, the mechanical properties of Q235B steel plates are better than that of Q235A steel plate.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
