430 Stainless Steel Flat Bar SUS430 GB/T1220 1Cr17 1.4016 Stainless Flat Bar

Excellent formability, easy stamping, bending and machining
Cost-effective ferritic stainless steel with good atmospheric corrosion resistance
Stable magnetic property, ideal for magnetic application scenarios
Bright surface finish achievable for decorative applications
Low maintenance for indoor and mild outdoor decorative projects

Product Overview

430 Stainless Steel Flat Bar (SUS430 / 1.4016 / X6Cr17 / 1Cr17) is manufactured under GB/T 1220 standard. It is the most common ferritic stainless steel grade, featuring single-phase ferrite microstructure and magnetic property.

Our 430 stainless flat bar is supplied in hot rolled pickled or cold rolled bright surface. It offers superior ductility for forming processes and good resistance to atmospheric corrosion. Compared with austenitic grades like 304, 430 provides obvious price advantage, though its corrosion resistance is limited in harsh chloride environments.

Typical applications include household appliances, decorative trim, architectural decoration, kitchen components and indoor decorative parts. We offer custom cut-to-length service, surface polishing and full EN 10204 3.1 mill test certificates for global B2B buyers.

FAQs

What is the equivalent grade of 430 stainless steel flat bar?

430 stainless steel flat bar 1Cr17 (GB/T1220) is equivalent to SUS430, 1.4016 and X6Cr17.

Is SUS430 stainless steel magnetic?

Yes, 430 is ferritic stainless steel, it has magnetic property, unlike non-magnetic 304 austenitic stainless steel.

What is the difference between 430 and 304 stainless flat bar?

430 is ferritic, cheaper, magnetic, good for forming and indoor decoration. 304 is austenitic, non-magnetic, much better corrosion resistance for outdoor and sanitary applications.

Can you cut 430 stainless flat bar to custom sizes?

Yes, custom cutting service is available to meet your required length and dimensions.

What surface options are available for 430 flat bar?

Hot rolled pickled, cold rolled bright and polished surface are all available.
