AISI 416Se Bolting Products
AISI 416Se is listed in the MARTENSITIC STAINLESS STEEL material family. The reference data below should be checked against the governing product specification, product form and delivery condition before selection or certification.
The reference chemistry table for AISI 416Se lists Chromium (Cr): Typically about 11–18% depending on grade; Carbon (C): Controls hardenability and attainable hardness; grade dependent; Nickel/Molybdenum (Ni/Mo): Present in selected grades to tune toughness or corrosion resistance; Sulfur/Selenium (S/Se): Present in free-machining variants such as AISI 416/416Se. Confirm exact limits and analysis tolerances against the governing standard and product form.
The mechanical-property table for AISI 416Se lists Tensile Strength: Approx. 650–1500 MPa; Yield Strength: Approx. 400–1200 MPa; Elongation: Approx. 5–25 %; Hardness: Approx. 180–500 HB HB. These are reference entries; supplied condition, dimensions, test method and governing specification control the requirements, and the figures are not design allowables.
Werkstoff / EN cross-reference for AISI 416Se: 1.4005. This comparison does not guarantee interchangeability; confirm chemistry, product form and condition against the governing specification.

AISI 416Se combines the characteristics of its stainless-steel family with grade-specific alloying and heat-treatment behavior suited to its intended service.
Martensitic stainless grades can be hardened and tempered to achieve useful strength.
Higher-carbon grades such as 440A/440B/440C can reach high hardness.
Provides useful general corrosion resistance, generally below austenitic grades in severe chloride service.
Free-machining variants improve cutting performance but require attention to corrosion and toughness trade-offs.
AISI 416Se is selected for engineered components and bolting where the material characteristics of this grade match the service environment.
AISI 416Se is considered for bolts and studs when its grade-specific corrosion, strength and temperature characteristics meet the service requirement.
AISI 416Se is considered for valve and pump parts when its grade-specific corrosion, strength and temperature characteristics meet the service requirement.
AISI 416Se is considered for shafts and pins when its grade-specific corrosion, strength and temperature characteristics meet the service requirement.
AISI 416Se is considered for cutting and wear components when its grade-specific corrosion, strength and temperature characteristics meet the service requirement.
Specify heat-treatment condition before using mechanical-property values.
Balance hardness against toughness and corrosion resistance.
Check weldability before welding martensitic grades; preheat/post-weld treatment may be required.
The commonly listed Werkstoff / EN cross-reference for AISI 416Se is 1.4005. Treat this as a grade comparison, not a guarantee of interchangeability. Verify chemistry, product form, condition and governing specification against the supplier certificate before substitution.
