Solutions for wrong layer problem of NM400 material meaning

ASTM a588 steel beam NM400 material meaning not only has high tensile and yield strength, but also has good atmospheric corrosion resistance due to its small copper content. Due to its high strength, its NM400 material meaning weight is less than that of A36 steel section without reducing strength. At the same time, it is the best material for outdoor application, the surface is orange.

NM400 material meaning, Q345D seamless pipe is low-alloy high-strength structural steel. It is named as low-alloy because of a small amount of alloy elements in the steel. Q345D seamless pipe is mainly used for construction and engineering structures. The carbon content of Q345D seamless pipe is ≤ 0.18%. Due to the effect of alloy elements, the yield strength of Q345D seamless pipe is 25% - 150% higher than that of carbon structural steel pipe with the same carbon content. Q345D seamless pipe can reduce the weight of steel structure, save steel products and effectively extend the service life of steel structure.

NM400 material meaning annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of NM400 material meaning annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. NM400 material meaning annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our NM400 material meaning products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
