Capital Industrial Enterprises, based in Delhi, is a trusted manufacturer and supplier of high-quality Case Hardening Steel in India. With over 55 years of industry experience, we supply case hardening steels engineered to deliver a hard, wear-resistant surface combined with a tough and shock-resistant core, making them ideal for high-performance mechanical components.

What is Case Hardening Steel?

Case hardening steel is specially designed to undergo surface hardening processes such as carburizing, carbonitriding, or nitriding. These processes create a hard outer layer while retaining a ductile and tough inner core, ensuring excellent wear resistance without compromising impact strength.
