Grindtech Piston Pins are made from high quality Alloy Steel (16MnCr5,17Cr3, SCM415, SAE8620 etc) and are of fine microstructure. The Manufacturing is performed on the state of the art machinery to achieve perfect dimensions (Roundness  within 2 microns, Concentricity Max 0.3mm, Surface Finish 0.1Ra Max.) and quality. All the Pins are hardened and tempered and are maintained between 58HRC to 64HRC hardness  and case depth of 0.5mm to 1mm. These Pins are mainly made for Pistons made by Grindtech, but for past many years , other Piston manufacturers also rely on Grindtech Pins Only.
