ABRASION RESISTANT STEEL (Wear Resistant Steel)

Description:

AR400, AR 450 , AR 500 ,AR550 and AR 600 are high hardness conventional low alloy martensitic steel grades for use in applications requiring high resistance to wear, impact and abrasion. These steels have a nominal hardness of 400, 450 ,500 ,550 and 600 HB respectively. The low carbon and alloying elements incorporated with heat-treated intense roller quenching and/or the tempering process ensure an optimal combination of hardness, toughness and weldability.

Welding and Cutting Methods

Welding Method	AR plates are very convenient in welding .Lower carbon equivalent of plates results good weldability . And all conventional welding methods like submerged arc welding , inert gas welding, manual electric welding can be applied .
Cutting Methods	AR Plates may cut easiliy at site with different cutting methods like Oxy-fuel cutting, Laser cutting, Plasam cutting , Waterjet cutting and Pug cutting methods.
UltraSonic Testing	Thickness above 8mm ,all plates are UT tested and controlled against class S2, E2 according to EN 10160
Precautions	AR plates are quenched and subsequently tempered then by default stress relieved plates; quality may reduce with exposure of temperature above 200 ºC while cutting or handling of plates.
