Abrasion Resistant Steel Plate-XAR

XAR Abrasion Resistant Steel Plate

XAR Abrasion Resistant Steel Plate


With the advantages of high hardness, quenching and tempering heat treatment, through adding special chemical elements, AGICO supplies XAR (Extra Abrasion Resistant) Steel plate product of different grades are developed ( XAR 400, XAR 450, XAR 500,XAR 550, XAR600) tailored for all applications: mining, heavy equipments in steel mills, cement industry, agricultural machinery. Normally hardness of XAR Steel differs due to the delivery state, for example, after annealing to soft, Hardness of XAR 600 at room temperature is 300HB (max), after hardening or heat treatment, it increases to 550 HB(min).



  • XAR 400 steel plate: this grade is the most commonly used steel grade with normal abrasion resistant level, it has extraordinary cold formability and weldablity, its abrasion resistant property doesn’t get weekend when the temperature is below 400℃.
  • XAR 450 steel plate: this grade is a upgraded version of XAR400 with abrasion resistant characteristic improved, the working temperature remains below 400℃.
  • XAR 500 steel plate: maintains formable and weldable characteristics, with element B added, it has higher level of wear resistance for conveyors, crushers, lorries, etc. It shall be delivered as water quenched.
  • XAR 550 and XAR 600 steel plate: cold forming is not allowed for the high hardness, with Ni element added, it is delivered as water quenched or soft-annealed steel.
