Mining operations demand tough equipment that can withstand extreme impacts, stresses, and wear, day in and day out. Hardox HiAce is a recent steel grade developed by SSAB with the sole purpose of resisting corrosive wear. This wear steel has a nominal hardness of 450 HBW, the
same as the well-established grade Hardox 450. Under non-corrosive wear conditions, they both provide the same high service life.
The distinction lies in how the steels perform when exposed to acidic low pH environments. If corrosion is present, Hardox HiAce can increase service life by two to three times compared to a 450 HBW steel, depending on the abrasive materials and the acidic conditions.
This made Hardox HiAce a natural choice when the company wanted to design and manufacture new reclaimer buckets. Hardox HiAce was used for the bucket’s floor and sides, which are exposed to corrosive materials. Based on the mining conditions these buckets are operating in, the company expects to get twice the service life compared to its previous buckets.
