Auto Transmission 20crmnti Carburized Forging Ring

Forging transforms a solid from one shape to another through plastic forming, while casting transforms liquid metal into a solid shape. Forging is a solid-to-solid process, whereas casting is a solid-liquid-solid process.

Quality is determined by external observation for surface defects like cracks or wrinkles, and internal testing for chemical composition, mechanical properties, and structural integrity using specialized instruments.

The process includes pier roughening, elongation, punching, and expanding. Ring rolling is primarily used for expanding holes in ring forgings, while free forging uses a horse screw.

The product uses 45# structural carbon steel, which offers low price, good cutting performance, and high hardness after quenching and tempering.
