Information on tungsten: sources, properties and uses

Stainless Steel and Valve Steel

Tungsten is added to ferritic-austenitic stainless steel (so-called “stainless super duplex steel”).  Such steel exhibits excellent corrosion resistance and strength properties.  Due to their pronounced resistance against stress corrosion cracking, fatigue, pitting, crevice and erosion corrosion they are ideal materials for components in offshore, waste water, sea water desalination and chemical plants with aggressive chloride-containing media.
