SUS 430 stainless steel

SUS 430 Chemical Properties

The main chemical components of SUS 430 include chromium, iron, carbon, nickel and copper. The addition of chromium gives it anti-oxidation properties and forms a protective oxide film. The low content of carbon makes it stable at high temperatures. Additionally, SUS 430 does not contain nickel, which makes it relatively economical in terms of price.
