How to recognize nm400 steel grade quality

"As Covid 19 spreads around the world, all unnecessary businesses and factories have been closed in Italy this week. South Korea's POSCO, the world's fifth-largest steelmaker, announced on March 24th that it would close its NM400 steel grade wire-processing centre near the northern Italian city of Verona from Thursday March 26th until April 3rd. POSCO has already closed two wire-processing centres in Delhi and Pune. Two wire processing centers in Malaysia and Thailand also announced last week that they will be closed until March 31."

Our company is a specialized technical support and after-sales service organization - customer service center. At the same time, we have provided excellent technical NM400 steel grade personnel and strong technical support for our company, and cultivated an excellent after-sales team for our company. Our company will appoint a full-time service manager to be responsible for the unified coordination of technical support and NM400 steel grade after-sales service of the project.

The bridge steel plate is mainly used for erecting railway bridges, highway bridges, sea crossing bridges, etc. The bridge steel plate is required to have high strength and toughness, 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 NM400 steel grade should also have good welding performance and low notch sensitivity. If you want to have a more comprehensive and detailed understanding of bridge steel plate, welcome to visit our official website for consultation.

We have transportation department and shipping department to coordinate logistics and delivery. Seamless connection between inland transportation and sea transportation ensures smooth delivery, saves transportation time and delivers goods in the first time. During the sea transportation, we will update the freight progress for customers on a regular basis, so as to facilitate the tracking of customers and make preparations for receiving goods leisurely and timely.

The basic phases of NM400 steel grade, structural steel in the annealed state are ferrite and carbide. The alloy elements are dissolved in ferrite to form alloy ferrite, which depends on solid solution strengthening to increase strength and hardness, but at the same time reduce plasticity and toughness. The addition of alloying elements reduces the carbon content of the eutectoid point, which increases the proportion of pearlite in the structure and reduces the distance of the pearlite layer. This also increases the strength of the steel and reduces the plasticity.

Our company has strict quality control standards. If you want to visit our factory, you are welcome at any time! We produce a lot of steel products every month to export NM400 steel grade to all over the world. Because our customers are from all countries, they will order a large number of steel products from our company every month.
