MIL-S-22216 - 301 Stainless Steel Sheet (Military Specification)
MIL-S-22216 is the Military Specification for 301 Stainless Steel sheet for aerospace and defense applications. This military specification establishes government procurement requirements for 301 stainless steel sheet, including chemistry, mechanical properties, testing, and documentation requirements for defense system applications where military specification material certification is required.
301 stainless steel per MIL-S-22216 is used in military aerospace structures, defense equipment enclosures, and high-strength stainless sheet metal applications requiring compliance with military material standards and full traceability to MIL-S-22216 requirements.
What is 301 Stainless steel ?
301 is an austenitic chromium-nickel based stainless steel that is non-magnetic in the annealed condition but becomes magnetic when cold worked. The high strength and corrosion resistance of this grade of stainless steel makes it useful for a variety of applications.
Properties of MIL-S-22216
Under 1/4 hard condition, 301 stainless steel offers a minimum of 125,000 PSI tensile strength and 75,000 PSI yield strength. It has a good balance between strength and formability. It remains non-magnetic after annealing but develops partial magnetism after undergoing cold work.
Typical Applications
301 stainless steel per AMS 5517 is commonly used in:
- Aircraft components and structural parts
- Springs, clips, and fasteners
- Automotive trim and hardware
- Architectural and industrial sheet applications
