Graded Cast Iron Casting

We specialize in manufacturing high-quality Graded Cast Iron Castings that deliver superior mechanical properties, dimensional precision, and outstanding durability for industrial applications. With our in-house foundry and CNC machining capabilities, we provide both un-machined and fully machined castings, precisely tailored to meet the specifications and performance demands of our clients.

Our graded CI castings are manufactured using advanced metallurgy practices and are available in a wide range of grades such as FG200, FG260, FG300, and others as per IS, ASTM, or custom international standards.

What Are Graded Cast Iron Castings?

Graded cast iron castings are iron-carbon alloys with controlled compositions and specific mechanical properties, categorized by their tensile strength, hardness, and machinability. Each grade is designed to meet particular performance criteria—whether it’s shock resistance, thermal conductivity, or compressive strength.
