Import Hardox wear plate 450 is defended by the wear-resistant steel Brinell hardness 450HB
Hardox defended by up to 450 Brinell hardness of 450HB is a wear-resistant steel, has a good cold resistance, mainly used in anti-wear condition. Hardox defended 450 with very good weldability.
Application dump truck cars, containers, crushers, plate, into the feeder, feed hopper, elevator, edge board, conveyors, bucket, blades, gears, sprockets, etc.

Test Brinell hardness, HBW, according to EU standard EN ISO 6506-1, sampling 40 tons per furnace steel, steel milling off the surface of 3 mm, then the surface of the test.
The same batch (furnace) of the plate thickness 15 mm for each change have to do the hardness test.
Delivery status quenching
Hardox defended by up to 450
Sizes up to 450 Hardox defended thickness can supply 3 *) -80 mm. Size more details on the information, please refer to our comprehensive product manual.
*) Less than 4 mm thick steel plate needs special agreement

General technical requirements
Delivery requirements, please refer to our comprehensive product manual
Heat treatment and processing Hardox defended 450 with quenching (if necessary, to tempering after quenching) for its mechanical properties. However, if the plate after use or preheating temperatures in excess of 250 ° C
Then its performance can not guarantee and delivery performance under the same conditions. Hardox 450 do not need to be defended by any further heat treatment.
In welding, cutting, grinding and other machining steel process, the need to take appropriate safeguards health and safety precautions. Especially grinding, due to steel sheet
Surface with paint, may produce high concentrations of fine particles of dust. If you need please contact us: our technical service department will provide more detailed information
