AISI 416 Martensitic Stainless Steel Chemical Composition & Properties, Grade, Chart and PDF Online

AISI 416, which is a stainless martensitic material, is a widely used crate for its high quality machinability and corrosion resistivity. The chemical composition of stainless steel usually amounts to about 0.15% of carbon, 1.25% of manganese, 12-14% of chromium, 1% of silicon, 0.04% of phosphorus, and 0.03% of sulfur. Therefore, this balance provides it with its strength, hardness and ability to withstand wear and corrosion. Alloy steel AISI 416 is commonly applied in cases requiring high mechanical properties including valves, shafts, gears and pumps. Its grade designation gives its positioning as part of the grade classifications as laid out in the American Iron and Steel Institute. Engineers and designers frequently get to the PDFs or charts where material properties and specifications are listed. This information they use for selection of the most appropriate material for their specified engineering projects that would guarantee optimal performance and a longer service life.

Advantages and Disadvantages of AISI 416 Martensitic Stainless Steel


  • High Machinability: Good machinability, especially in the annealed condition.

  • Good Corrosion Resistance: Offers adequate protection in most corrosive conditions.

  • Heat Treatable: Can be heat treated to obtain suitable mechanical characteristics.

  • Fair Weldability: Enables welding using general procedures with preheat and post weld heat treatment.


  • Limited Corrosion Resistance: Tendency to corrode in conditions with chlorides or sulfuric acid.

  • Low Toughness: Comparatively lower toughness than austenitic stainless steel.

  • Susceptible to Cracking: May crack during heat treatment if not well regulated.

  • Sensitive to Cold Working: Cold working causes loss of corrosion resistance and may lead to crack sensitivity.
