White Iron Wear Buttons
Laminated white iron Wear buttons are unique wear resistant materials in that they combine very high wear resistant qualities of a high chrome cast iron (15/3CrMo, 700 BHN - 63 HRC) with a weldable & high impact toughness mild steel through a metallurgical bond to create a product that is exceptionally resistant to impact and abrasion while retaining.
Very easy to use, no pre or post heating when welding. Available in diameters from 60mm up to 150mm. Develop your own layout and pattern to suit your particular wear protection solution.
Dome&Flat Shaped Round: Perfect solution for ground engaging applications as on adaptor teech, shovels, buckets, heavy earth moving equipment etc. Can well use them in conjunction with Chocky Bars, Wear Plates or individually to provide protection or security under the toughest impact and wear abrasion circumstances.
