550, with a nominal hardness of 550 HBW, offers a unique combination of excellent abrasion resistance, crack integrity and workshop performance. Hard and tough, it helps to extend the service life of wear parts in heavy-duty and high wear applications.
550 is specially designed for heavy wear applications and makes a great alternative to 12% manganese steel castings, 500 Brinell wear plate or bimetals. The additional 50 Brinell you gain in hardness, when upgrading from conventional 500 HBW steels, will increase wear life, though not at the expense of crack integrity. 550 is typically used for wear parts in industries like mining, quarrying, mineral processing, earthmoving and recycling.
Dimension Range
550 is supplied as plate in thicknesses of 0.315 – 2.559″, up to 114.173″ in width and up to 575.984″ in length. in length. More detailed information on dimensions is provided in the dimension program.
