According to foreign media reports, despite the impact of the coronavirus epidemic, most German screw A588 Grade A, Grade B, Grade K low alloy steel 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 A588 Grade A, Grade B, Grade K low alloy steel market due to the impact of the closure of local steel mills in Italy.
The microscopic strength of the A588 Grade A, Grade B, Grade K low alloy steel, wear-resistant steel plate refers to the strength of the hard phase, but the higher the strength, the higher the wear resistance. Strength is the basis of high-quality wear resistance of wear-resistant steel plates, but the relationship between strength and wear resistance is not proportional; wear-resistant steel plates are often wear-resistant, the root cause is that there are hard particles and soft conventions.
