Valin LY Steel revealed on the 28th that the cross-cutting heat treatment workshop of the company's 2250 hot-rolled plate plant had worked overtime

for several days and rolled more than 130 tons of NM600 products, which
were delivered to customers as soon as possible. This batch of products is thehighest grade in the domestic wear-resistant steel series and is also the first rolling by LY Steel.

Starting from technological innovation and improving product quality, Valin

LY Steel actively implements supply-side reforms. In response to the current

trend of lightweight steel products, LY Steel is committed to creating higher

and thinner high-strength and wear-resistant steel products. In the field of wear-resistant steel, LY Iron and Steel has achieved a full range of products from NM300 to NM600, including the highest-level and thinnest domestic wear-resistant steel products. Relying on the advantages of good shape quality, processing performance and welding performance, LY Steel wear-resistant steel is widely used in various domestic well-known dump truck companies and cement equipment industries, and it is in a leading position in China.

LY Steel's high-strength carriage body steel contains various grades ranging from 450MPa to 900MPa. It is one of the few domestic steel companies that canproduce thin-gauge, wide-section, high-strength carriage body steel. The yield strength of the steel plate reaches 900MPa, which is the highest level in China,has become the first choice for major domestic dump truck companies. LY Steel also took full advantage of the ultra-thin specifications steel of the sheet production line to develop 550MPa high-strength and thin steel for containers and trailers. Among them, the thinnest can produce 1.2mm thickness, and the
actual maximum yield strength reaches 650MPa.

The boom plate of a well-known domestic crane manufacturer has been using imported products in the past. Through technical research and development,
LYIron and Steel has produced a high-strength steel with a yield strength of
100MPa for the boom plate, which has good welding and bending properties. It not only helps customers realize the substitution of domestic materials and greatly saves costs, but also fills the blank of 1100MPa grade high-strength quenched and tempered steel plate for the 4mm thickness steel.
