Chemical Composition
The 304 Stainless Steel Rod owes its properties to a precise blend of elements:
This composition ensures the bar’s signature corrosion resistance and strength.
| Element | Percentage (%) |
|---|---|
| Carbon (C) | ≤ 0.08 |
| Chromium (Cr) | 18.0–20.0 |
| Nickel (Ni) | 8.0–10.5 |
| Manganese (Mn) | ≤ 2.0 |
| Silicon (Si) | ≤ 1.0 |
| Phosphorus (P) | ≤ 0.045 |
| Sulfur (S) | ≤ 0.03 |
| Iron (Fe) | Balance |
Mechanical Properties of 304 Stainless Steel Bar
Here’s how the 304 Stainless Steel Rod performs under testing:
These metrics make 304 stainless steel rods ideal for demanding applications.
| Property | Value |
|---|---|
| Tensile Strength | 515–690 MPa |
| Yield Strength (0.2%) | ≥ 205 MPa |
| Elongation | ≥ 40% |
| Hardness (Brinell) | ≤ 201 HB |
| Density | 8.0 g/cm3 |
Chemical Properties: Resistance to Acids and Alkalis
The 304 Stainless Steel Rod resists corrosion from mild acids (e.g., acetic acid) and alkalis, making it suitable for food-grade environments. However, it’s less effective against strong acids like hydrochloric acid or prolonged exposure to chlorides, especially in warm conditions. Always assess your environment before use.
Things to Note (Limitations)
Â
- High Temperatures: Prolonged exposure above 800°C may reduce corrosion resistance.
- Chloride Exposure: Susceptible to pitting in saltwater or chloride-rich settings.
- Heavy Mechanical Stress: Not ideal for extreme load-bearing compared to higher grades like 316.
For such conditions, consult our team for alternatives.
Corrosion Data
| Environment | Corrosion Resistance | Notes |
|---|---|---|
| Atmospheric (Urban/Rural) | Excellent | Resists rust in typical outdoor conditions. |
| Mild Chemicals | Good | Handles dilute acids and cleaning agents well. |
| Salt Spray (Chlorides) | Moderate | Avoid prolonged exposure to saline settings. |
| Fresh Water | Excellent | Ideal for non-chlorinated water exposure. |
| Industrial Atmospheres | Good | Resists mild pollutants; monitor heavy smog. |

Welding and Fabrication Tips
Welding the 304 Stainless Steel Bar is straightforward with these methods:
- TIG/MIG Welding: Preferred for precision and clean finishes.
- Electrode Welding: Suitable for thicker sections.
Tips:
- Use low heat to prevent warping.
- Post-weld annealing isn’t typically required, but it can enhance corrosion resistance.
- Machining is easy with sharp tools and proper lubrication.
For 304 stainless steel threaded rod or complex shapes, our factory offers pre-fabricated options.
What Customers Say About Our 304 Sheets
Frequently Asked Questions
Q: How does 304 differ from 316 stainless steel?
A: The 304 Stainless Steel Bar is more affordable and suits general-purpose needs, while 316 offers superior corrosion resistance, especially in marine settings, due to added molybdenum.
Q: What sizes are available for 304 stainless steel rods?
A: We provide 304 stainless steel rod sizes from 1mm to 500mm in diameter, customizable to your specs.
Q: What makes 304 Stainless Steel Bar different from 303 stainless steel?
A: The 304 Stainless Steel Rod offers better corrosion resistance due to its higher chromium and nickel content, while 303 is optimized for machinability with added sulfur. For general use, ss 304 bar is the stronger all-round choice.
Q: Are custom sizes available for 304 stainless steel round bar?
A: Absolutely! Our factory provides 304 stainless steel round bar in diameters from 1mm to 500mm, with custom lengths and finishes tailored to your needs. Contact us for details!
Q: Is 304 stainless steel bar stock suitable for high-temperature applications?
A: The 304 stainless steel bar stock performs well up to 800°C, but prolonged exposure may reduce corrosion resistance. For extreme heat, consider higher grades or consult our team.
Q: Can it be used outdoors?
A: Yes, ss 304 rod resists rust in most outdoor conditions, but avoid coastal or chloride-heavy areas.
