wear resistance of nm400 inventory decreased

HARDOX steel wear resistance of NM400 is a famous wear-resistant steel brand. It is designated as Hardox400, hardox450, hardox500, hardox600. It has good wear resistance in general and special applications.

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 wear resistance of NM400 processing services of cutting steel pieces. Now we have built a business system integrating steel plate, steel plate cutting and wear resistance of NM400 steel deep processing. The company provides one-stop solution for customers with lower price, higher quality and faster response speed.

At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick wear resistance of NM400 steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.

Oxygen (O) is a harmful element in steel such as wear resistance of NM400. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.

The company has a professional after-sales service team and good after-sales service reputation, providing full and uninterrupted after-sales service, to ensure timely and rapid solution to customer problems. The company is recognized as a 5-star brand of market quality cost performance and customer satisfaction by Market Research Center, and rated as "AAA credit enterprise of enterprise credit evaluation", and also a leading steel producer and service provider in the world.
