What is ASTM equivalent of nm550 steel wear resistance and their difference

At the same time of doing well in NM550 steel wear resistance production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the NM550 steel wear resistance technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.

Vanadium is a weak deoxidizer. Adding vanadium into NM550 steel wear resistance steel can reduce the adverse effects of carbon and nitrogen, effectively improve the strength, but sometimes also increase the tendency of welding hardening, vanadium is also a commonly used trace alloy element.

The recent improvement in demand is also reflected in NM550 steel wear resistance social inventory. This year, the growth rate of NM550 steel wear resistance social inventory has slowed down compared with the same period last year, which indirectly reflects that the demand of NM550 steel wear resistance this year is better than that of last year. In addition, NM550 steel wear resistance production, which has set new highs again and again, has slowed down this month, with a slight decline. The decline of NM550 steel wear resistance production will also alleviate the relationship between supply and demand.

The abrasion resistant NM550 steel wear resistance steel plates, which also known as wear resistant steel plates, are among our main business scope. There are various abrasion resistant steel grades on the market. Among them, NM400, NM450, NM500, HARDOX400, HARDOX500, AR400, AR500, etc. are most popular. Meanwhile, NM400, HARDOX400 and AR400 are equivalent to each other. NM500, HARDOX500 and AR500 are also equivalent abrasion resistant steel materials.
