Normalizing S355j2g3 Alloy Steel Forged Ring

Forging transforms solid metal from one shape to another through plastic forming processes like extrusion or punching, either hot or cold. 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 includes pier roughening, elongation, punching, and expanding. Free forging uses a horse screw to expand holes, while ring rolling uses rolling. Both methods aim to achieve the desired shape and structural integrity.

We offer flexible customization including full customization, minor customization, customization from designs, and customization from samples. Shapes include Round Bar, Square, Shaft, Ring, and Cylinder.

The product is certified under GB/T19001-2016 and ISO9001:2015 standards, ensuring quality management and product consistency.
