HH-750B Hardfacing FCW Welding Wire for CCO Wear Plate
High chromium wear-resistant plate flux cored wire, less welding spatter, smooth welded deposit smooth , high welding efficiency and high recovery rate.
Charateristics
HH-750B produces a wear-resistant, primary carbide-containing weld deposit. It is very resistant to abrasion.
Microstructure: High-chrome-high-carbon hard alloy on iron base: C – Cr – Fe.
Machinability: Grinding only
Cutting: Not suited for flame-cutting
Deposit thickness: 30 mm in Multil layers.
Application
Recommended particularly for the produce Chromium carbide overlay wear plate(CCO wear plate, or Bimetal plate) or wear resistant pipe, can also be used for hardfacing chutes, sieves, conveying channels, liners,hoppers.,etc. The application temperatures should not exceed 450℃.
