What’s up guys?!?!?! Michael here with Michael Talks Metal. Today, our video will introduce another common stainless steel found in specifications for aerospace applications. Several variants exist that we will address in the next weeks.
This week we will focus on the basic type 410 alloy with the UNS designation S41000. 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.
Typical annealing temperature is from 1550 to 1650 deg F followed by slow cooling.
Typical hardening range is 1750 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.
Is 410 magnetic? Yes, 410 is magnetic
