Repairing or maintaining equipment that is protected by abrasion resistant, or AR plate, is an inevitable task in the mining industry, and one that can also be tricky. Taking certain precautions and choosing the most appropriate filler metal is one of the most important steps to ensuring welding success, and in turn, long, reliable equipment life.
Typical AR plate products have numbers ranging from 200 to 500 in their name-AR 200, AR 400, AR 500, for example. These numbers typically designate the hardness of the material in Brinell (BHN), which can easily be converted into alternative hardness scales such as Rockwell B (HRB) or Rockwell C (HRC). Typically, the higher the hardness of the ...
