410 Stainless Steel - AMS 5611 - AMS 5612 Aircraft Quality - AQ to AMS 2301

This week we will focus on the  type 410 alloy modified to control any ferrite present in the hardened condition. Full Transcript: https://www.michlinmetals.com/410-stainless-steel-ams-5611-ams-5612-aircraft-quality-aq-to-ams-2301/
The UNS designation S41001. It is a martensitic alloy that can be heat treated to moderate hardness and strength levels. Typical applications require some strength and hardness but where the limited corrosion resistance of this 12% chromium alloy is adequate.  Elevated temperature applications are generally limited to a maximum of 1000 deg F.

This alloy is commonly supplied to aircraft quality AMS 5612 which requires AMS 2301 cleanliness.

Premium aircraft quality AMS 5611  requires Consumable Electrode Melting (CEM)  and AMS 2303 cleanliness.

Typical annealing temperature  is from  1550 to 1650 deg F followed by slow cooling.

Typical hardening range is 1700 to 1850 deg F followed by an air or oil quench depending on section size. Temper as required for desired hardness

Maximum corrosion resistance is in the fully hardened condition.
