AISI 414L Martensitic Stainless Steel Chemical Properties, Grades, Tables and PDF Online

AISI 414L is a long carbon, molybdenum containing martensitic stainless steel known for its extraordinary corrosion resistance and mechanical features. The fundamental constituents normally include sulfur, chromium, manganese, silicon, carbon, iron, phosphorus and a few others. This one has a microcomponent comprising of approximately 12% chromium and 1% molybdenum which has the ability to give you the maximum protection in almost all corrosion environments including those having acidic or chloride elements. This grade is known for its outstanding hardenability, hardness, and strength, hence is an ideal solution for applications requiring high level of mechanical performance while at the same time retaining great resistance to corrosion such as the aerospace, automotive, and industrial equipment industries. AISI 414L martensitic stainless steel endures the application load conditions of materials in components that are exposed to straining factors such as gears, shafts, and valves.

AISI 414L Martensitic Stainless Steel Chemical Composition And Grade Table

AISI 414L is low-carbon, molybdenum-bearing, martensitic stainless steel which features particularly strong corrosion resistance and high strength. Its chemical composition is usually made of chromium (12-14%), molybdenum (0.6-1.0%), manganese (1.0% max), silicon (1.0% max), sulfur (0.03% max), phosphorus (0.04% max), carbon (0.03% max) and iron to round off the figure. This grade is excellent in terms of toughness, good weldability, and has the resistance for various type of corrosion which make it suitable for industries of automotive, aerospace and oil & gas sector. Components which are to endure high tension and corrosive environments are usually the choice of AISI 414L.
