Free cutting steels are a group of steels that are specifically designed to be easy to machine or cut. They contain sulfur, lead, and other elements that help to reduce the amount of force needed to cut through the steel. This makes them ideal for use in manufacturing processes where a lot of cutting or machining is required. Some common examples of free cutting steels include 12L14, 1144, and 1215.

Established in 2001, the facility specialized in special steel production and inventory. In 2004, advanced equipment for hot rolled and forged products was integrated, forming a complete production and operation system including smelting, refining, forging, and heat treatment. Since 2005, export operations have expanded globally.
The state-of-the-art production lines feature leading-edge technology for various grades including bearing steel, stainless steel, alloy steel, high-speed tool steel, and die steel. The product range covers rounds, squares, flats, wire rods, sheets, pipes, and heavy forgings. The annual output for forged rounds alone reaches 60,000 tons.
