430 Wire

Type 430 Stainless Steel Wire

ASTM A580

Stainless steel grade 430 is a non-hardenable steel containing straight chromium, and belongs to the ferritic group of steels. This steel is known for its good corrosion resistance and formability, coupled with practical mechanical properties. It can be used in certain chemical applications due to its resistance to nitric acid. This product is often used for fasteners as well as lashing wire.

Can be supplied in bright and soap coated finish.
