FAQs

What is the equivalent grade of 304 stainless steel flat bar?

304 stainless steel flat bar 06Cr19Ni10 (GB/T1220) is equivalent to SUS304, 1.4301 and X5CrNi18-10.

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

304L is low carbon version of 304. It prevents intergranular corrosion after welding, ideal for heavy welding work. 304 is more cost-effective for non-welded or lightly welded parts.

Can you cut 304 stainless steel flat bar to custom lengths?

Yes, we offer custom cutting service to meet your required length.

Is 304 stainless flat bar suitable for outdoor use?

Yes, it performs well under normal atmospheric conditions. For coastal saltwater environment, we recommend 316L grade.

What surface options are available?

We supply hot rolled pickled surface and bright polished surface for 304 stainless flat bar.
