Durable Mining Equipment Forgings with High Quality Materials

Forging transforms a solid from one shape to another, while casting transforms shapeless liquid metal into a solid. Casting involves melting metal, whereas forging is a plastic forming process in the solid state, including extrusion, drawing, and punching.

Quality inspection involves external observation for surface defects like cracks or wrinkles, and internal testing for chemical composition, structure, and mechanical properties like tensile strength and hardness using specialized instruments.

The process includes pier roughening, elongation, punching, and expanding. Free forging uses a horse screw to expand holes, while ring rolling uses rolling for the same purpose.

The primary material is 45# structural carbon steel, known for low price, good cutting performance, and high hardness after heat treatment. Other options include S45C, 1045, and SM45.

The minimum order quantity is 1 piece.
