Quard® plates are produced at NLMK Clabecq, where they are treated in a state-of-the-art Quenching and Tempering unit. The slabs used are supplied by the NLMK’s Lipetsk production site. NLMK’s abrasion resistant steels are delivered with hardness of 400 HB (Quard® 400), 450 HB (Quard® 450), 500 HB (Quard® 500) and 550 HB (Quard® 550). Those plates are designed for construction and mining equipment (excavators, dump trucks, bulldozers, hoppers, mixers, etc.), as well as for machinery in very demand industries (recycling, agriculture, etc). Solid rocks, hard minerals, mining work is a journey to primary era. When resistance to wear becomes the key factor like in a mining environment Quard® provides the appropriate solution. Thanks to its hardness and its high resistance to wear, the abrasion resistant steel of NLMK Clabecq product lifetime of more than three times compared to the standard marks of structural steel and reduce the weight of the structural element by 40%. The abrasion resistant steel Quard® has proven to have a very long service life, even in permanent use.

Delivered in hardness up to 550 HB, QUARD® can be used for any machine, like mining excavators, tunnel diggers, crushers, …
Moreover, demanding manufacturers will appreciate the high workability of QUARD®, induced by the purity of its steel and the unique production process of NLMK Clabecq, where it is made. With easier cutting, bending and welding, they can gain in productivity throughout all the steps where QUARD® is used.
Through the use of QUARD®, it is possible to increase the life of the product for more than three times compared with conventional structural steel marks, and reduce the weight of the structural element by 40%.

Quard® plates are treated in a state-of-the-art Quenching and Tempering unit. The slabs used are supplied by the NLMK’s Lipetsk production site. Quard® abrasion resistant plates are delivered with hardness of 400 HB (Quard® 400), 450 HB (Quard® 450) and 500 HB (Quard® 500), with thicknesses ranging from 3.2 mm to 64 mm and widths from 1,500 to 3,100 mm.
They are designed for construction and mining equipment (excavators, dump trucks, bulldozers, hoppers, mixers, etc.), as well as for machinery in very demand industries (recycling, agriculture, etc). The use of Quard® may result in product lifetime being more than tripled when compared to products made from standard grades of steel.
