Piston pin material 20Cr, as shown in Table 1.
Table 1: Material parameter material Elasticity coefficient Poisson's ratio Density Tensile strength Yield strength 20Cr 2.05e11Pa 0.29 7.85e3Kg/ 835Mpa 540Mpa Considered the piston pin’s quality is very small oppositing to the piston quality, force of inertia also corresponding extremely small, cannot have the obvious influence to the piston pin stress.Therefore may define the piston pin to contact the region with the piston is the fixed restraint.

Their advantage in terms of cost effectiveness and material saving is outlined.
After very heavy cold reduction and strain ageing, this alloy has the distinction of achieving the highest combination of strength and toughness of all materials available currently.
For example in sugar industry materials of construction encounter wear and corrosion.
