316 stainless steel dowel pins are designed for high-precision alignment and secure fastening in environments where corrosion resistance is critical. Manufactured from marine-grade stainless steel, these pins are ideal for industries such as food processing, pharmaceuticals, chemical manufacturing, and offshore engineering.
What Are 316 Stainless Steel Dowel Pins?
Dowel pins are cylindrical metal components used to align, locate, or join machine parts during assembly. 316 stainless steel offers superior corrosion resistance compared to 304 stainless steel, thanks to its molybdenum content. It performs reliably in high-moisture, saltwater, acidic, and sterile environments where dimensional stability and durability are essential.

316 vs 304 Stainless Steel Dowel Pins
| Property | 304 Stainless Steel | 316 Stainless Steel |
|---|---|---|
| Corrosion Resistance | Moderate | Excellent (salt, acid, chemicals) |
| Suitable for Marine Use | No | Yes |
| Food Contact Compliance | Yes | Yes |
| Cost | Lower | Slightly Higher |
| Application | General-purpose | Critical and harsh environments |
316 stainless steel is the preferred choice when long-term reliability and resistance to pitting or chemical attack are required.
