The versatility of Coiled Spring Pins often times makes them the ideal fastener to meet the specific engineering and economic objectives of pinning applications. They are available in a wide variety of sizes, duties, finishes, and materials. Amongst the materials used to manufacture Coiled Spring Pins, stainless steel is often required for its high corrosion resistance. Coiled Spring Pins are most often manufactured from Type 302/304 and Type 420 stainless steel, but Type 316 is also available and is typically selected for its superior corrosion resistance. This paper takes a closer look at how Type 316 compares to Type 302/304, and discusses various applications and environments where it offers an advantage.
