Forging transforms solid metal from one shape to another through plastic deformation, including processes like extrusion and punching. Casting transforms liquid metal into a solid shape by pouring molten metal into a mold. Forging is a solid-to-solid process, while casting is a solid-liquid-solid process.

Quality is determined by external observation (checking dimensions, surface defects like cracks or wrinkles) and internal testing (analyzing chemical composition, macroscopic/microscopic structures, and mechanical properties like tensile strength and hardness using specialized instruments).

The process for circular forgings includes pier roughening, elongation, punching, and expanding. Free forging uses a horse screw for expanding holes, while ring rolling uses rolling. Both methods aim to achieve the desired shape and internal structure.

The primary material is 45# structural carbon steel (GB/T699-1999), which has a carbon content of 0.42-0.50%. Similar designations include S45C (JIS) and 1045 (AISI). The steel offers good cutting performance, high hardness after quenching, and excellent strength and toughness.

The Minimum Order Quantity is 1 Pc. The company supports flexible customization, including minor customization, customization from designs, and full customization.
