Virgo 39 is a 16% Cr, 5% Ni, 1% Mo low carbon martensitic stainless steel. The grade is specially designed to combine high mechanical properties including toughness and improved corrosion resistance properties when compared to other martensitic stainless steels, like 13 Cr and 13 Cr 4 Ni grades.

The alloy has been primarly designed to resist to erosion-corrosion or cavitation encountered in hydraulic applications.

The alloy is also used for hydrofoils legs, as anti-seismic compounds or offshore structures, boats, landing grids for helicopters… where the combined mechanical and corrosion resistance properties are needed.

Mining, cement plants, and hydraulic applications take also advantage of its combined abrasion-corrosion resistance properties.
