HARDFACING

Offshore Solutions (OSI) offers an exceptionally wide range of secondary processes that are applied to metals formed in hot or cold processes. Offshore Solutions' Supplier Quality Engineers determine the availability of the process within the metal forming facility, as well as the quality. If the internal secondary processes do not meet OSI standards then the processes are carried out in OSI-audited and qualified off-site secondary processing facilities. Offshore Solutions has audited, qualified and worked with QS-9000 and ISO certified secondary processing facilities in China for over 12 years. OSI is dedicated to managing your project on-site in China and delivering parts to you at lower prices but the same quality, service and terms as a domestic supplier.

Fusion hardfacing is a process by which weld materials, with superior properties than the substrate, are applied to the substrate. Often, two layers total 3 - 6 mm (1/4 - 1/2 in) thick are applied to reduce the surface hardness dilution of the relatively low-cost steel substrates in the expansive cobalt-base alloys. Hardfacing processes are very useful for improving wear and corrosion resistance to selected areas of machinery, such as cutting edges of earth-moving machinery. Common hardfacing techniques include arc, torch, and other processes.

Common Materials Used in Hardfacings

Hardfacings are good for substrate materials that are suitable for welding, such as low-carbon steel. The most common hardfacing materials are nickel alloys and iron/chromium alloys used in wear resistance and high stress abrasion. Common materials for hardfacing are listed as follows:
