What’s up guys?!?!?! This is Michael with Michael Talks Metal back for another stainless session today. This week our topic is type 430; a stainless steel alloy with the UNS designation S43000. It is a ferritic alloy and cannot be heat treated to increase hardness and strength levels.
Typical applications require the corrosion or oxidation resistance of this 17% chromium alloy. Elevated temperature applications are generally limited to a maximum of 1600 deg F.
Typical annealing temperature is from 1300 to 1450 deg F.
Is 430 magnetic? Yes, 430 is magnetic
430 SAE 51430 UNS S43000
