Factory Direct Sale Steel Ring Forging Steel Bar

Forging transforms solid metal into another shape, while casting transforms liquid metal into a solid shape. Forging is a plastic forming process in the solid state, whereas casting involves melting and pouring.

Quality is checked via external observation for surface defects like cracks or pits, 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 often used for expanding holes in ring forgings, differing from free forging methods.

45# steel has a tensile strength of at least 600 Mpa, yield strength of 355 Mpa, elongation of 16%, and section shrinkage of 40%.

We offer flexible customization including shapes (round, square, shaft, ring), surface treatments (black, rough, bright), and delivery conditions (quenching, normalizing, annealing).
