Description

MetcoClad™ 316L-SI is a gas atomized, nickel chromium stainless steel powder suitable for use with the laser cladding process. It is an austenitic-type stainless steel, similar to AISI Type 316L (UNS S31603), with a low carbon content that desensitizes the clad deposit to eliminate grain boundary carbide precipitation.


When applied using laser cladding, the properties are similar to, or better than, that of the bulk material because of the refined microstructure and low dilution during cladding. The clad offers good impact resistance at elevated temperatures and corrosion resistance in chloride environments. Molybdenum ensures good pitting and crevice resistance.


Silicon levels in MetcoClad 316L-SI are higher than AISI Type 316L. The higher silicon content acts as a fluxing agent that produces cleaner clad deposits. Please note that cladding parameters may have to be adjusted to accommodate the higher silicon content.

MetcoClad 316L-SI is recommended for corrosion overlay deposits on components used in the oil, gas and marine industries.
