Gr 400 Wear Plate
With a guarantee minimum surface hardness of 370 brinell (BHN), Gr 400-LE has replaced the more conventional Gr 360-LE.
Gr 400-LE is thru-hardened abrasion resistant steel, free of mill scale and offers good ductility. With excellent flatness and low in carbon (CEQ), this product is easily welded using conventional welding methods and low hydrogen consumables using no preheat.
During the manufacturing process, a fine grain size is achieved combining a micro-alloying technology with a controlled heat treatment. The micro structure improves low temperature toughness and cold formability and reduces the possibility of delayed cracking.
Gr 400-A is designed for applications where high impact may cause problems. This is available from 60mm up to 100mm thickness.
