Materials for making Connecting Rod

Connecting rods can be made from various grades of structural steel, aluminum, and titanium. Steel rods are the most widely produced and used as connecting rods. Their applications are best used for daily drivers and endurance racing due to their high strength and long fatigue life. The only problem with using steel rods is that the material is extremely heavy, which consumes more power and adds stress to the rotating assembly. Below mentioned materials are taken as connecting rod materials- Carbon Steel, High strength low alloy steel, Corrosion-resistant high strength low alloy steel, and Quenched and tempered alloy steel.

What is a Crank Pin?

A Crankpin is the part of the crank of a crankshaft to which the connecting rod is attached. Crankpins transfer up-and-down motion between the crankshaft and connecting rod. The big end of the connecting rod is connected to the crankpin of the crankshaft by way of a bearing. Connecting rods typically have two-piece crankpin bearings for connecting the lower end of the rod to a crankpin of a crankshaft. Crankpin meets the demands for high-performance engines, lightweight design, component reliability, and low through cost manufacturing. The crankpins are subjected to shock and fatigue loads. Thus the material of the crankpin should be tough and fatigue resistant. The crankpins are generally made of carbon steel, forged steel, and alloy steel. It also improves the strength of the component. The surface of the crankpin is hardened by case carburizing, nitriding, or induction hardening.
