ASTM A240 304L Stainless Steel Sheet & Plate – Engineered for Chemical, Food Processing, and Architectural Applications

Product Overview

ASTM A240-compliant 304L stainless steel sheet and plate is the industry-preferred low-carbon austenitic grade for applications requiring excellent corrosion resistance, superior weldability, and hygienic surface integrity—without the risk of intergranular corrosion after welding.

With a maximum carbon content of 0.03%, 304L (UNS S30403 / EN 1.4307) eliminates carbide precipitation in the heat-affected zone (HAZ), making it ideal for welded fabrications in demanding sectors such as chemical processing, food & beverage, pharmaceuticals, architecture, and cryogenic engineering.

Manufactured to strict ASTM A240/A240M, ASME SA-240, and EN 10088-2 standards, our 304L sheets and plates offer consistent quality, full traceability, and global compliance—ensuring reliability from fabrication through decades of service.

Why 304L? Key Advantages by Industry

Industry Critical Need How 304L Delivers
Chemical Processing Resistance to mild acids & solvents Stable in organic acids (acetic, citric), dilute nitric/phosphoric acid; non-reactive surfaces
Food & Beverage Hygiene, cleanability, FDA compliance Smooth, non-porous finish; meets FDA, EC 1935/2004; resists bacterial growth
Pharmaceutical Purity & contamination control Low leaching; compatible with CIP/SIP cleaning; non-toxic
Architecture Aesthetics + durability Attractive finishes (brushed, mirror); resists urban/rural atmospheric corrosion
Cryogenics Toughness at low temps Retains ductility down to –196°C (–320°F)

Unlike standard 304, 304L requires no post-weld annealing, reducing cost and complexity in large-scale welded structures.
