Product OverviewOur ASTM A240-compliant 304 and 304L stainless steel plates are
precision-manufactured hot-rolled flat products designed for
demanding industrial, structural, and process applications.
Available in standard widths of 1.5 meters (1500mm), 1.8 meters
(1800mm), and 2.0 meters (2000mm), these plates offer exceptional
dimensional consistency, corrosion resistance, and mechanical
performance across a broad thickness range (typically 3.0 mm to
40.0 mm, with options down to 2.0 mm upon request). Produced under strict quality control systems aligned with ASTM
A240/A240M, ASME SA240, and EN 10088-2 standards, our hot-rolled
304/304L plates are ideal for fabricators seeking reliable,
weldable, and cost-effective stainless solutions for pressure
vessels, storage tanks, heat exchangers, cryogenic systems, food
processing equipment, and more. Both AISI 304 (UNS S30400) and low-carbon 304L (UNS S30403)
variants are stocked, allowing customers to select the optimal
grade based on welding requirements and service
environment—ensuring long-term durability without sensitization or
intergranular corrosion.
Key Features & Benefits- ✅ Multiple Standard Widths: Choose from 1500mm, 1800mm, or 2000mm
to match project layout and minimize waste.
- ✅ Hot-Rolled Finish (No.1): Annealed and descaled surface provides
excellent flatness and readiness for further processing (e.g.,
machining, coating, or polishing).
- ✅ Wide Thickness Range: From 2.0 mm to 40.0 mm—suitable for light
cladding or heavy-duty structural use.
- ✅ Superior Corrosion Resistance: Performs reliably in oxidizing
acids, organic acids, alkaline solutions, and atmospheric exposure.
- ✅ Excellent Weldability: 304L is especially recommended for welded
assemblies >6mm thick where post-weld annealing isn’t feasible.
- ✅ Cryogenic Compatibility: Retains toughness at temperatures as low
as –196°C, making it suitable for LNG and liquid gas applications.
- ✅ Full Traceability & Certification: Each batch includes an EN
10204 3.1 Mill Test Report (MTR) with chemical and mechanical data.
