S20430 Stainless Steel Spring Wire
ASTM A313 UNS S20430 Stainless Steel Spring Wire
S20430 is a chromium-magnesium austenitic stainless steel with an addition of 2-4% copper and nitrogen of 0.05-0.25%. Due to the addition of copper the alloy has better formability than 201 and 304. The copper improves corrosion and resistance to stress corrosion cracking in certain media.
