304L Stainless Steel Coil | 022Cr19Ni10 Low Carbon Stainless Steel Coil

Ultra-low carbon content, effectively avoid intergranular corrosion after welding
Excellent weld performance, no post-weld heat treatment required
Retain good ductility and forming property same as standard 304
Suitable for long-term service in corrosive welded structures
Available for hot rolled and cold rolled with full range of sizes

Product Overview

304L stainless steel coil (GB 022Cr19Ni10) is low-carbon variant of 304 austenitic stainless steel, equivalent to AISI304L, SUS304L and EN 1.4307 (X2CrNi18-9). Reduced carbon content eliminates chromium carbide precipitation along grain boundaries during welding, which solves intergranular corrosion risk.

We provide cold rolled and hot rolled 304L coil. Common surface finish: 2B, BA, No.1. We support custom slitting to narrow strip. This grade is widely selected for welded pressure vessels, chemical pipelines, storage tanks, marine auxiliary equipment and food processing machinery.

FAQs

What is the difference between 304 and 304L stainless steel coil?

The main difference is carbon content. 304L carbon ≤0.03%, can avoid welding intergranular corrosion. If heavy welding work, choose 304L.

What are main applications of 304L stainless coil?

Welded pressure vessel, chemical tank, water treatment pipe, marine auxiliary parts, food processing equipment.

Can 304L stainless steel coil be slit into narrow strip?

Yes, custom slitting service is available with strict width tolerance for stainless strip.

Is heat treatment required after welding 304L?

Normally no need post-weld heat treatment, which reduces construction cost.

What certificates can be provided?

EN10204 3.1 MTC, SGS/BV third-party inspection can be arranged before shipment.

What is MOQ for 304L stainless steel coil?

MOQ 5 ton for stock sizes; for custom non-standard thickness, MOQ will be higher.
