Chemical Composition
| Element | Percentage (%) |
|---|---|
| Chromium (Cr) | 17.0 - 19.0 |
| Nickel (Ni) | 8.0 - 10.0 |
| Sulfur (S) | 0.15 - 0.35 |
| Carbon (C) | 0.15 max |
| Manganese (Mn) | 2.0 max |
| Silicon (Si) | 1.0 max |
| Phosphorus (P) | 0.20 max |
| Iron (Fe) | Balance |
Mechanical Properties
| Property | Value |
|---|---|
| Tensile Strength | 620 - 860 MPa |
| Yield Strength | 260 - 400 MPa |
| Elongation | ≥35% |
| Hardness (Rockwell B) | ≤100 HRB |
Chemical Properties
The 303 Stainless Steel Fasteners resist certain corrosive agents:
- Acids: Fair resistance to organic acids like acetic acid
- Alkalis: Moderate performance in mild alkaline conditions
- Limitations: Reduced resistance in chloride-rich or acidic environments due to sulfur content
The sulfur enhances machinability but limits corrosion protection.
Things to Note (Limitations)
When using 303 Stainless Steel Fasteners, consider these points:
- Avoid marine or high-chloride settings to prevent pitting corrosion
- Not ideal for prolonged use above 760°C (1400°F) due to carbide precipitation
- Sulfur content makes welding challenging—opt for alternatives if needed
Corrosion Data for 303 Stainless Steel
| Environment | Corrosion Resistance |
|---|---|
| Dry Indoor Atmosphere | Excellent resistance to rust |
| Potable Water | Moderate, up to 200 mg/L chlorides |
| Mild Organic Acids | Fair performance at room temperature |
| Saltwater Exposure | Prone to pitting and surface corrosion |
Best Welding and Manufacturing Practices
Fabricating 303 SS Fasteners requires careful consideration:
- Welding: Not recommended due to sulfur-induced cracking; if necessary, use 308L or 310 filler with post-weld annealing
- Manufacturing: Excels in machining; sandblasting service improves finish and wear resistance
- Tips: Use sharp tools and coolants for optimal stainless steel hardware production
Our China factory ensures precision in every ss fastener.
What Customers Say About Our SS Fasteners
Frequently Asked Questions
Q: Why go for 303 Stainless Steel Fasteners instead of 304?
A: If you need parts that machine like butter—think intricate stainless steel screws—303’s your pick. It’s cheaper and tougher to beat for mild settings, though it trades off some corrosion resistance.
Q: How does sandblasting service help these fasteners?
A: Sandblasting service toughens up the surface, cuts down wear, and gives 303 Stainless Steel Fasteners a clean, rugged look. It’s a game-changer for parts taking a beating.
Q: Are these okay for wet environments?
A: They’re fine in dry or mildly damp spots—like indoors or covered areas. But toss them near saltwater, and you’ll see pitting fast. Stick to 316 for the wet stuff.
Q: What’s the top use case for these fasteners?
A: Precision machining gigs—think aerospace fittings or stainless steel hex head bolts for machinery. Anywhere you need fast production without crazy corrosion demands, 303 shines.
Q: How fast can I lock in a price?
A: Drop your details—size, type, how many—on our site, and our China team will hit you with a SS Fasteners price in under a day. Quick and painless.
Q: Can I get these in oddball sizes?
A: Yep, customized sizes are our thing. Tell us what you need, and we’ll craft Fasteners to fit—perfect for those one-off jobs.
