chemical composition of NM450 structural price

The weldability of chemical composition of NM450 is good. It means that under certain process and construction conditions, chemical composition of NM450 can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.

For chemical composition of NM450, wear-resistant plate, the change of temperature in production and processing will directly affect the properties of the whole plate, so the effect of isothermal treatment of wear-resistant steel plate has been studied all the time. The results show that the continuous cooling transformation curve, microstructure, phase and similar structural phase of wear-resistant plate also change under different heating temperature.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
