We have a few choices when it comes to choosing a piston pin. 5115 Material pins are chromium alloy and steel case hardened to 58-64 Rockwell C designed for normal wear and tear. 52100 Material Pins are high carbon chromium-bearing steel made of aircraft quality alloy and case hardened to 54-56 Rockwell C for high load capacity. 9310 Material Pins are high quality low carbon and are case hardened to 59-63 Rockwell C for turbo or nitrous applications.
5115 Material Pin
- Standard grade chromium alloy steel
- Case hardened to 58-64 Rockwell C
- Ground to a surface finish of.15 Ra or better
- Designed to withstand the normal wear and tear of an aftermarket engine
52100 Material Pin
- High carbon, chromium-bearing steel
- Aircraft quality alloy
- Case hardened to 54-56 Rockwell C
- Through hardened
- Ground to a fine finish
- Designed for high load capacity
- Designed for outstanding wear and abrasion resistance
9310 Material Pin
- High quality, low carbon, case hardened steel
- Case hardened to 59-63 Rockwell C
- Ground to a superfinish (.025 Ra or better)
- Designed for use in applications which require high surface strength combined with high core toughness
- Excellent to use in applications where high contact stress is combined with high shock and impact loading, such as turbo / nitrous applications
