NLMK Lipetsk, the flagship site of NLMK Group, has started commercial deliveries of S500MC and S550MC high-strength HRC (yield strength 500 and 550 MPa) to the Russian market. These steel products are used in the manufacture of dump truck bodies, scrap trucks, truck chassis, cranes and other special purpose machinery. The use of high-strength steel in structures enables a 20% increase in carrying capacity, reduced weight, and lower fuel consumption per ton of cargo.
S500MC and S550MC steel grades are 40% stronger than general-purpose hot-rolled products, and are used in heavy-duty structures and components. The metal undergoes special thermomechanical treatment at NLMK’s Hot Rolling Mill to acquire its strength properties.
High-strength steel sheets come in the following dimensions: 4 mm to 8 mm thick, up to 1,500 mm wide, and up to 12 meters long. Customers can order in small batches of up to 20 tons with truck delivery. Customers also have the option of adding high-strength Quard© plates to their order, which NLMK supplies to Russia from its NLMK Clabecq plant in Belgium.
As part of its high-strength hot-rolled steel development program, NLMK plans to start pilot deliveries of S600MC grade before the end of the year. (NLMK/Ukrainian metal)
