VACUMET® 1.4418

UNS #S42010

VACUMET 1.4418 Stainless is a double vacuum melted variant of 1.4418 Martensitic Stainless steel. 1.4418 is specially formulated for those applications requiring high mechanical strength combined with improved corrosion resistance relative to traditional martensitic stainless steels such as AISI 410. 1.4418 Stainless steel is weldable and cold formable. The low inclusion content of VACUMET 1.4418 Stainless and its controlled microstructure significantly improves the alloy’s toughness, weldability, and formability and makes VACUMET 1.4418 Stainless an ideal choice for high pressure thin-walled applications. VACUMET 1.4418 Stainless is commonly supplied in the full hard condition designated as QT900.
