Cold-Rolled & Hot-Rolled 304L Stainless Steel Plate – Excellent Fabrication Properties for Industrial and Medical Equipment
Product Overview
304L stainless steel plate, available in both cold-rolled (CR) and hot-rolled (HR) forms, delivers unmatched versatility for precision industrial components and critical medical equipment. As the low-carbon variant of Type 304 (UNS S30403 / EN 1.4307), it offers superior weldability, excellent formability, non-magnetic behavior, and reliable corrosion resistance—all without the risk of intergranular corrosion after welding.
Engineered to meet ASTM A240/A240M, ASME SA-240, and EN 10088-2 standards, our 304L plates are ideal for applications where hygiene, dimensional accuracy, structural integrity, and ease of fabrication are paramount—from surgical instrument trays to chemical reactor shells.
Cold-Rolled vs. Hot-Rolled 304L: Choosing the Right Form
| Feature | Cold-Rolled (CR) 304L | Hot-Rolled (HR) 304L |
|---|---|---|
| Thickness Range | 0.5 mm – 4.0 mm | 4.5 mm – 100 mm |
| Surface Finish | Smooth, uniform (2B or BA standard) | Slightly scaled, matte (No.1 finish) |
| Dimensional Tolerance | Tighter tolerances (±0.05 mm typical) | Wider tolerances (±0.5–1% thickness) |
| Strength | Higher yield due to work hardening | Lower strength, fully annealed |
| Formability | Excellent for precision bending, stamping | Better for heavy forming, rolling |
| Typical Uses | Medical enclosures, electronic housings, thin tanks | Structural supports, pressure vessels, base plates |
Both forms retain the non-magnetic austenitic structure and corrosion resistance that define 304L—ensuring performance consistency across your supply chain.
Why 304L Excels in Industrial & Medical Applications
✅ Medical Equipment Advantages
- Non-magnetic: Safe for use near MRI machines, imaging systems, and sensitive diagnostics
- Hygienic surface: Smooth finishes inhibit bacterial growth; compatible with sterilization (autoclave, gamma, EtO)
- Biocompatible & FDA-compliant: Meets FDA 21 CFR, ISO 10993, and EU 1935/2004 for indirect food/medical contact
- Easy to clean: Resists staining from blood, saline, alcohols, and disinfectants
✅ Industrial Equipment Advantages
- Welds without post-heat treatment: Eliminates downtime in tank, duct, and skid fabrication
- High ductility: Elongation ≥40% enables deep drawing, spinning, and complex bends
- Cryogenic toughness: Performs reliably down to –196°C (–320°F)
- Chemical resistance: Withstands organic acids, alkalis, and mild solvents common in processing
