ARMOUR-X® Wear Plate
6mm to 25mm
Up to 2.4m, cut to size
Up to 6.0m, cut to size
ARMOUR-X™ is superior to conventional Q&T plate for bending, drilling, shearing, gas cutting & welding. The hardness level of AMOUR-X™ is lower than conventional 500 BHN steels, with far greater abrasion resistance. These characteristics extend wear life, reduce replacement frequency & installation weight.
Evaluations undertaken at our customers sites with ARMOUR-X™ wear plate installed shows it offers outstanding results in heavy-duty, high-impact, abrasive environments & after extended periods shows negligible wear providing 2 to 3 times service life compared to standard industry wear plate.
When welding ARMOUR-X™ as well as any AR plate in the 400-500 BHN classification preheat should always be used (80°C up to 20mm thick, 125°C for 25mm, 175°C for 40mm, 200°C for 50mm). This will help to ensure a slower cooling rate and prevent cold cracking in the HAZ. This preheat should be applied to at least 150mm beyond the weld joint.
When roll forming ARMOUR-X™ it is always preferred the plate be rolled in line with the grain of the plate. Roll speed should be at the slowest possible setting (variable speed rolls preferred). Once the rolling process begins and the plate is undergoing plastic deformation, do not stop the rolls because this condition can sometimes set up shear stresses that will initiate cracking.
The alloying elements in ARMOUR-X™ make it somewhat more difficult to drill than conventional 500BHN wear plate. Co-Balt bits seem to work the best. The bits should be ground to an included point angle of 150 degrees, the flute lip is ground to a 5 degree positive rake with an approximate land of width of 0.8mm.
ARMOUR-X™ can be cut with a conventional oxy-acetylene torch, grinding flame cut edges 3mm after cutting is always good practice to help eliminate cracking. If plasma is used it must be noted this process creates more edge stresses on AR plates in the 400-500BHN range due to the extremely high heat and rapid cooling rate of this process.
