Xar 400 Wear Abrasion Resistant Sheet
XAR400 is a special structural steel with high wear resistance, generally the higher the hardness, the higher the wear resistance. This wear-resistant special structural steel has an average hardness of 400 HB and is quenched, or hardened and quenched, to give it a good martensitic-bainitic microstructure. The addition of molybdenum, nickel and boron alloys ensures a uniform texture throughout the thickness direction.

XAR400 wear steel plate heat treatment
The desired mechanical properties are obtained as a result of austenitising in special equipment followed by quenching and, if appropriate, tempering at less than Ac1. Quenching directly after hot rolling is equivalent to conventional quenching. The heat treatment depends on the chemical composition and the thickness of the material. To avoid loss of hardness, the material must not be heated above 250°C.
XAR400 wear-resistant steel plate welding
If the general requirements of welding are taken into account, both manual and automatic welding are suitable for this material. In order to avoid the occurrence of cold cracks at the butt weld, it is important to note that the welding consumables are selected with a very low hydrogen content. For austenitic welding consumables, preheating is generally not necessary. The temperature depends on the thickness of the plate and the residual stresses in the structure. The preheating temperature should not be higher than 250 °C.
