Stainless steel grade 430 ASTM A580 Bright soft wire
430 Alloy Description
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.
Applications: Cooking utensils;Fasteners;Food processing;Interior
trim applications
