Cold rolled sheet wear resistance of nm400 production line

According to foreign media reports, despite the impact of the coronavirus epidemic, most German screw wear resistance of NM400 steel producers still maintain a good level of production. This is in sharp contrast to the situation in other European countries and Germany's domestic steel mills, which are suffering from a slowdown due to the spread of the epidemic. Lotter kummatt Stahl, a local distributor, told customers on its website: "there is no reason at present to believe that German steel mills such as Riva and ferralpi are no longer able to serve the wear resistance of NM400 market due to the impact of the closure of local steel mills in Italy.

The wear resistance of NM400, wear-resistant plate after VD treatment is generally high-quality wear-resistant plate with high added value. In addition to the strict requirements for the composition of wear-resistant plate, the requirements for the anti-fatigue pull-out damage performance of the wear-resistant plate are also very strict. Therefore, the non-metallic inclusions, especially the large non-metallic inclusions and brittle inclusions, must be strictly controlled.

NM500 wear plate is Chinese abrasion resitant steel. NM500 steel is equivalent to AR500, HARDOX500, XAR500 and so on materials. The surface Brinell hardness of NM500 wear plate is ≥470 HBW. The NM500 steel is consists of max. 0.38% Carbon, 0.70 Silicon, 1.70 Manganese, 0.020 Phosphorus, 0.010 Sulfur, 1.20 Chrome, 1.00 Nickel, 0.65 Molybdenum, 0.050 Titanium, 0.0005-0.006 Boron, min. 0.010 Als, etc.. According to GBT24186, the max. thickness of wear resistance of NM400, NM500 wear plate is 70mm.
