Piston Ring Definition

Chemical performance, metallographic, and thermal treatment of raw material.

Successively  developed  piston ring made by steel, Ductile Iron, and high-alloy cast iron

The quality of materials has ranked internationally as leading grade, to met requirements of various engines.

Steel piston rings offer high tensile strength and exceptional durability, making them ideal for high-performance and high-stress applications.

Ductile iron piston rings are easier to machine and can be precisely manufactured and customized to meet specific engine requirements.

High-alloy cast iron piston rings can significantly enhance their wear resistance, and the alloying elements also improve the corrosion resistance of the piston rings.
