Mechanical Properties
| Property | Value |
|---|---|
| Tensile Strength | ≥ 515 MPa |
| Yield Strength | ≥ 205 MPa |
| Elongation | ≥ 40% |
| Hardness (Brinell) | ≤ 201 HB |
| Hardness (Rockwell) | ≤ 92 HRB |
Chemical Properties
The 304 SS sheet resists a variety of chemicals effectively:
- Acids: Handles organic acids and dilute inorganic acids well.
- Alkalis: Strong resistance to alkaline solutions.
- Chlorides: Performs reliably in low-chloride environments, though pitting may occur with prolonged exposure.
Environmental Limits: Avoid use in high-chloride settings or temperatures exceeding 60°C (140°F) for extended periods to prevent stress corrosion cracking.
Things to Note (Limitations)
While highly versatile, the 304 stainless steel plate has some constraints:
- High Temperatures: Avoid continuous exposure between 425-860°C (797-1580°F) due to carbide precipitation risks.
- Marine Settings: Susceptible to pitting in saltwater or coastal environments.
- Heavy Welding: For thick sections, consider 304L for improved weldability.
Corrosion Data for Cold Rolled Stainless Steel Sheets
| Environment | Corrosion Rate |
|---|---|
| Rural Atmosphere | < 0.0025 mm/year |
| Industrial Atmosphere | 0.0025 - 0.0076 mm/year |
| Freshwater | < 0.0025 mm/year |
| Seawater (Static) | 0.0076 - 0.025 mm/year |

Best Welding and Manufacturing Practices
- Welding: Use standard fusion welding techniques with or without 308L filler metals. Post-weld annealing is optional for thin 304 sheets but recommended for thicker sections.
- Forming: Easily shaped via bending, stamping, or deep drawing.
- Machining: Requires sharp tools and lubrication to avoid work hardening during cutting or drilling.
These properties make our 304 stainless sheet a favorite for manufacturers.
What Customers Say About Our 304 Sheets
Frequently Asked Questions
Q: How does a 304 stainless steel differ from 316?
A: 304 stainless steel is a cost-effective option that provides good corrosion resistance, making it suitable for a wide range of general-purpose applications. On the other hand, 316 stainless steel includes molybdenum, which significantly improves its resistance to chlorides and harsh chemicals, making it the preferred choice for marine environments or chloride-heavy settings like coastal areas.
Q: Are 304 stainless steel plates suitable for outdoor use?
A: Yes, 304 stainless steel plates are suitable for outdoor use in most climates due to their solid corrosion resistance. However, in high-salt environments, such as near the ocean or in areas with heavy road salt exposure, they may be prone to pitting corrosion, so caution is advised.
Q: What’s the cost of a 3mm 304 steel sheet?
A: The cost of a 3mm 304 stainless sheet depends on factors like dimensions, surface finish, and the quantity ordered. Prices can vary accordingly, so for an accurate and tailored quote, please reach out to us with your specific project details.
Q: What are the standard sizes available for stainless sheets?
A: Our stainless steel sheets come in standard sizes such as 4×8 feet and 5×10 feet, with thicknesses ranging from 0.3mm to 100mm to suit various needs. Additionally, we offer custom cutting services to provide sizes tailored to your specific project requirements.
Q: Can 304 sheets be used in food processing equipment?
A: Yes, 304 are an excellent choice for food processing equipment. Their strong corrosion resistance, ease of cleaning, and non-reactive properties ensure they meet hygiene standards and maintain safety in food-related applications.
Q: What surface finishes are available for stainless steel sheets?
A: We provide a wide range of surface finishes, including 2B (smooth, matte), BA (bright annealed), No.4 (brushed), HL (hairline), Mirror (reflective), Etched, and Embossed. These options allow you to choose based on both functional performance and aesthetic preferences.
