Description

Diamalloy™ 1003 series products are austenitic, nickel-chromium stainless steel powders, similar to Type 316L. They produce thermal sprayed coatings that are bright, dense and resistant to corrosion and wear. These coatings can easily be machined to a very good finish with ordinary steel tools.


The dense coatings produced by these products are particularly recommended for applications that require protection against corrosion, cavitation and mild particle erosion at ­temperatures less than 540 °C (1000 °F). These coatings are also used for the salvage and build up of worn or mismachined steel parts. In addition, these coatings work-harden in service, making them suitable for packing areas on pump shafts and bearing surfaces on motor shafts.


Coatings of these materials contain enough molybdenum to guarantee particularly high resistance to pitting and crevice corrosion in chloride environments, and they also exhibit high impact resistance and tensile strength at elevated temperatures.

Other

Diamalloy 1003-1 is designed for application using HVOF. It produces coatings that are smoother, denser and less oxidized than coatings of ­Metco 41-series, and are more suitable for corrosion applications. The high silicon content in Diamalloy 1003 series products provides enhanced oxidation and sulfidation resistance comparted to Diamalloy 1013.
