General Gear Materials:
In order to achieve intended performance, reliability and life of the gears it is essential to select suitable gear material. For high load capacity hard material is required which is challenging to machine; whereas for high precision work easy to machine materials are used. Therefore, precision work has lower hardness ratings and strength. Light non-ferrous materials are fine for lightweight and small jobs. The gear materials are wide ranging from non-ferrous, ferrous metals and light-weight metals, to different plastics. Also, the final selection is based upon the properties of material and application requirements.
Cast Irons (SG Iron):
Cast Iron is advantageous to save machining costs in the production of large gears, and its various grades are widely used for the same. Cast steels offer this advantage along with higher tensile and yield strength. But cast iron provides superior internal damping properties, under dynamic conditions. Cast Iron is supplied in different grades and forms, and SG Iron grade is commonly used for large gears.
Carbon & Alloy Steels:
Carbon Steels and Alloy Steels are two main divisions of the steels. Carbon steels offer cost-effective and easy machining along with ability to be hardened. But its major disadvantage is that it is lower corrosion resistant. Alloy steel is generally a mixture of iron and other important elements. It covers a wide range of alloys from low-grade to high-grade to special high alloys providing utmost strengths. Moreover, the alloy steels are most versatile with their wide range of heat treatment properties.
Stainless steels are used for specific applications because of its high cost factor. Divided into two varieties Stainless Steels have 300 series which is called true stainless steels and can resist all corrosive conditions. Another is the 400 series which is not truly stainless, it offer less corrosion resistance only in certain conditions, otherwise considered stainless.
Presently numerous material standards are followed all over the world. All the standards are developed keeping specific properties as well as applications in mind. The standards cater details on chemical composition, material hardness, mechanical properties, heat treatments etc. for accomplishment of desirable properties.
