Quard® is a martensitic abrasion resistant steel with average hardnesses between 400HBW and 550HBW. it is produced at NLMK Clabecq, where they are treated in a state-of-the-art Quenching and Tempering unit.
The steel plates are specific for applications used in hard environments and subject to wear. Quard is recommended for mining and earthmoving equipments and for machines in the recycling or cement industry. The use of Quard® may result in product lifetime being more than tripled when compared to products made from standard grades of steel.
Buckets, knives, grapples, dumper bodies and on road tippers, refuse haulers, scrap containers and scrap presses, feeders, skips, screw conveyors, screeners, crushing and pulverizing equipment, etc.
|Grades||Thickness (mm)||Width (mm)|
|Quard 400||4-50 mm||1500-3100|
|Quard 450||3.2-64 mm|
|Quard 500||4-40 mm|
|Quard 550||6-30 mm|
|Quard is a martensitic abrasion resistant steel. Its very resistance to abrasive wear and impact makes it ideal where a long service life is required.|
Easier to process
The way of making our steel slabs, of rolling our plates and heat treating them gives to Quard (and Quend) specific mechanical properties that leads to a superior workability. From the cutting till the machining, surveys prove that our material gets the preferences in the workshops for their excellent behaviour.
