34CrNi3Mo Carbon Structure Steel Ring Forging Steel Bar

Dingxiang Jinyu Forging is located in Dingxiang, China’s renowned hometown of forging. We specialize in manufacturing ring flanges, ring forgings and forged round bars made of 34CrNi3Mo steel. Equipped with complete production lines for forging, heat treatment, machining, physical and chemical inspection as well as flaw detection, we can deliver finished flanges with one-stop service.

34CrNi3Mo is a high-strength alloy structural steel featuring outstanding hardenability. After quenching and tempering, it boasts excellent strength, toughness and fatigue resistance, ideal for heavy-load and high-pressure working conditions. Our products are formed by ring rolling technology with continuous and intact metal flow lines, free of internal porosity and cracks, and stable dimensional accuracy. Custom flanges complying with GB, ASME and GOST standards are available, covering sizes from DN15 to DN2500.

Our flanges are widely applied as core connecting components for wind power, mining, heavy industry and oil & gas equipment. All incoming raw materials undergo batch-by-batch testing. Post-forging flaw detection and stress relief treatment are carried out to strictly control mechanical properties. With sufficient monthly production capacity, we accept bulk orders from home and abroad, delivering stable and reliable export-grade products.
