Ductile Iron Castings Properties Attracting Many Indian Industries

Castings are precision products offered by manufacturers in India. Ductile castings are one of the variants of casting products that are known for their tensile strength, elongation, and yield strength. However, all these properties don’t always help the industries to determine the suitability of casting parts in a particular application. The tensile properties can’t explain the wear resistance, fatigue strength, and other things that are crucial for every industry to know for installing in specific application.

Let’s discuss all these properties in detail which motivate manufacturers of ductile castings in India to carry out bulk production for many industrial clients.

Wear resistance- Ductile castings can be hardened to 60 HRC by proficient engineers via conventional heating methods. The ductile iron becomes similar to carburized and hardened steel in terms of wear resistance after heat-treatment. Manufacturers tested the abrasion resistance feature of ductile castings and as compared to steel, ductile castings have low abrasion resistance property.

Noise reduction- Gray and ductile iron consist precipitated graphite that helps in diminishing vibration in machine tool parts, hydraulic parts, and gears. When compared to steel castings, India based ductile castings manufacturers found that ductile iron is 100 times better in reducing noise and vibration. This is why engineers have replaced steel with ductile iron for hydraulic gear pumps to lower noise and machining cost.

Fatigue strength- After conducting some tests in foundry, engineers have discovered that heat treated ductile castings possess approx 90% of the fatigue strength of hardened and carburized gears.

More industries are adopting Ductile Castings India instead of steel for several applications. No doubt, these are great alternatives to steel in gear and other applications where all these properties are essential to consider. Machinability of ductile castings provides cost reduction opportunities for bulk parts/ production and reduces tooling costs.
