Crankshaft Materials
As one of the most crucial parts of a engine, and with an appearance that directly influences the work life of the engine, it is vital to choose crankshaft material that is capable of bearing a heavy load and changing torque. Due to that, users must choose the material based on the actual application needs of the engine. Traditional choices are as follows:
Nodular cast irona. The yield strength and tensile strength of nodular cast iron can reach up to 600-900MPa.
b. It's easy to produce a crankshaft using nodular cast iron, especially as nodular cast iron is generally inexpensive.
c. The nodular cast iron features an excellent shock absorption, abrasion resistance and no cracks.
a. Quality carbon steel is known for its strength and capability to meet normal demands. It costs less than alloy steel, and has a better ductility than nodular cast iron.
b. Quality carbon steel also features an excellent plasticity, physical performance, chemical performance and mechanical performance.
a. Alloy steel has better tensile strength, yield strength and ductility than nodular cast iron and quality carbon.
b. Alloy steel also has an outstanding strength and impact resistance. Compared to quality carbon steel, it has a better physical, chemical and mechanical performance.
