Facts About 420 Stainless Steel

When Alliant Metals began, we started as a metals distributor for the 300/400 series stainless. We noticed the demand in New England to be pertinent and continuing to grow. Since then, we added services and a larger selection of raw metals to be go-to for all stainless steel needs. That said, we have spent the past 30 years educating ourselves about the different metal grades we carry, including 420 stainless steel. We would love to share some information with you.

• 420 stainless steel is the martensitic higher carbon version of 410 and 416 stainless steel
• This metal contains a minimum of 12% chromium
• The chrome elements are what give 420 its corrosion resistance
• It is known to have the highest corrosion resistance in its fully hardened condition
• 420 hardening occurs by heat treatment (between 1850° and 1950° F)
• Maximum hardness for 420 is approximately 500 Brinell
• 420F stainless steel was created to be an easier machined version of 420
• 420 stainless is difficult to weld because of its hardening characteristics
