304/304L Austenitic Stainless Steel Plate

304 and 304L are classic 18-8 austenitic stainless steel grades. 304 contains carbon ≤0.08%, while 304L is low-carbon version with carbon ≤0.03%, effectively avoiding intergranular corrosion after welding. It features excellent corrosion resistance, ductility, formability and weldability, non-magnetic under annealed condition.

304 and 304L are the most widely used 18-8 austenitic stainless steel grades in global metal procurement. 304 is the standard carbon version, while 304L is its low-carbon variant. The low carbon content of 304L minimizes chromium carbide precipitation during welding, greatly reducing the risk of intergranular corrosion in welded joints.

This stainless steel plate delivers balanced performance: reliable general corrosion resistance in atmospheric, freshwater and mild chemical environments, excellent ductility, formability and superior weldability. It is non-magnetic in the annealed state and can be easily fabricated, bent and deep drawn.

Our products comply with various international standards, including ASTM, GB, EN, and JIS; a Material Test Certificate (MTC) can be provided for every batch. We maintain ready stock in our own warehouses and offer services such as cutting, slitting, and surface finishing, ensuring rapid delivery.

Core Performance (Comparison of 304/304L)

Corrosion Resistance: General austenitic, resistant to atmospheric/weak acid/weak alkali; 304L has stronger resistance to intergranular corrosion (no heat treatment required after welding)

Weldability: 304L is low carbon, less prone to sensitization and cracking in the weld heat-affected zone, suitable for chemical/pressure vessels/pipelines

Formability: Elongation ≥40%, easy to bend/stamp/roll, suitable for deep processing

Hygiene: Complies with FDA 21 CFR 177, EU 1935/2004, suitable for food/pharmaceutical applications

Temperature: -196℃~800℃, resistant to low temperatures/heat

Grade: 304 (S30400, 1.4301) / 304L (S30403, 1.4307)
Low-carbon 304L: ideal for heavy welding applications
Good resistance to rust and mild corrosion
Excellent forming, bending and deep drawing performance
Multiple surface options for decorative & industrial use
Strict quality inspection, full traceability with MTC
Custom cutting & size customization, in stock for quick delivery

Warehousing Management

Before each batch of steel leaves the factory, a complete process inspection is strictly carried out. From chemical composition, mechanical properties to dimensional tolerance and surface quality, each item is carefully checked to ensure compliance with national standards and export regulations. At the same time, the quantity, packaging and rust prevention treatment are also verified. An original factory warranty certificate is attached, guaranteeing the quality. Before shipment, inspection photos are provided. Any non-compliant items will not be released, and the quality is fully controllable throughout the process. This ensures your overseas purchasing is safe and worry-free.

All items are visually inspected before delivery. No cracks, deformation, rust, scratches or cutting marks are allowed; edges must be smooth. Only visually sound products will be shipped.

Thickness, width, length, wall thickness, outer diameter have been measured. Straightness, curvature, torsion, diagonal tolerance all meet the corresponding tolerance requirements.

Quality inspection includes: mechanical property tests (yield strength, tensile strength), elongation rate, impact energy, hardness testing, chemical composition testing, process performance testing, etc.

Inspection according to packaging requirements: secure binding, moisture-proof film, rust-proof paper, export fumigation/fumigation-free wooden crates, shipping marks, gross weight, net weight, etc.

We will provide full reception services to support the customers' on-site inspection of the goods.
