1.4418 Stainless is a martensitic stainless steel specially designed for those applications
requiring high mechanical properties combined with improved corrosion resistance relative to traditional martensitic steels.
Typical applications can be found in fields like automotive, industrial, and pressurized fuel systems
for direct injected engines, fittings on fuel rails, fuel pumps, and injector bodies.
