The introduction of direct injection turbocharged engines has increased the need for higher performance connecting rods, able to withstand higher compressive loads in operation. In this respect, new materials with high compressive yield strength and fatigue performance for powder-forged connecting rods, such as HS150, HS160, and HS170M, were developed and successfully introduced in production. Among them, HS170M, currently used to manufacture connecting rods for several high performance engines, not only has exceptional strength, but less variation in mechanical properties as a function of its chemical composition variation within the specified limits compared to other powder-forged materials.
