    Stainless steel 430 is a non-hardenable steel containing straight chromium, and belongs to the ferritic group of steels.

    Product introduction

    Stainless steel 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. 
    430F stainless steel is usually provided in bar form to be used in automatic screw machines. factory Standard AISI ASTM hot/cold roll stainless steel plate

    Possible Alternative Grades

    Grade Reasons for choosing 430
    430F Higher machinability than 430 is needed in bar product, and reduced corrosion resistance is acceptable
    434 Better pitting resistance is required
    304 Slightly higher corrosion resistance is needed, together with greatly improved ability to be welded and cold formed
    316 Much better corrosion resistance is needed, coupled with greatly improved ability to be welded and cold formed
    3CR12 Lower corrosion resistance is acceptable in a cost-critical application
