1.7228 50CrMo4 Forged Steel Rolled Gear Ring

High-Quality Forged Steel Rings for Industrial Applications – Precision Engineered, Heat-Treated, and Ready for Custom Machining

Our premium forged steel rings are meticulously crafted to meet the rigorous demands of heavy-duty industrial environments. With a maximum outer diameter reaching up to 5000 mm and seamless rolled ring forgings weighing up to 12,000 kg, these components are ideal for applications requiring exceptional strength, durability, and dimensional stability. Whether you're sourcing alloy steel rings for pressure vessels, turbine components, or large-scale mechanical systems, our production process ensures consistent quality and performance across global markets.

Each Forged Ring undergoes a minimum forging reduction ratio of 3.1:1—ensuring superior grain structure refinement and enhanced mechanical properties. Surface finish is maintained at 6.3 µm Ra or as specified by client requirements, offering optimal surface integrity for subsequent machining or direct use. We offer both rough and finish machining options, allowing customers to choose based on their specific engineering needs without compromising tolerances or structural integrity.

The heat treatment process includes quenching and tempering using advanced natural gas heating furnaces, trolley furnaces, and dedicated heat treatment equipment. This ensures uniform hardness distribution, improved toughness, and resistance to thermal fatigue—critical for high-stress environments such as petrochemical processing, power generation, and aerospace manufacturing. The material selection spans multiple international standards including UNS S32615 (ASTM A182/A182M), Steel 10Х17Н13М2Т (GOST 5632-2014), Steel 20X25H20X2 (GOST 5632-72 / AISI 314), 12Х18Н10Т (GOST 5632-72), and 09G2S (GOST 19281-2014)—covering austenitic stainless steels, carbon steels, and specialty alloys designed for corrosion resistance, elevated temperature service, and mechanical reliability.

Manufactured with state-of-the-art processing tools such as horizontal lathes, vertical lathes, CNC machining centers, and hydraulic band saws, our facility delivers precise geometry control and repeatability. Testing is performed using hydraulic universal testing machines, impact test chambers, and broaching equipment to verify compliance with mechanical specifications including tensile strength, yield point, Charpy impact values, and dimensional accuracy. Every batch is traceable and documented, supporting ISO and ASME quality standards relevant to global industries.

These forged rings find extensive application in oil & gas pipelines, nuclear reactors, marine propulsion systems, mining machinery, and industrial gearboxes where failure is not an option. Their ability to withstand extreme temperatures, dynamic loads, and corrosive media makes them indispensable in critical infrastructure projects worldwide.

Customers consistently praise the consistency in material performance, the precision of final dimensions, and the support provided during custom order development. Many have noted that the combination of robust metallurgy, controlled deformation during forging, and tailored heat treatment results in significantly longer service life compared to cast alternatives.

Common questions include whether we can accommodate non-standard sizes or special surface treatments like polishing or coating; yes, we provide full customization services based on technical drawings or engineering specs. Another frequent inquiry relates to lead times—typically ranging from 4 to 8 weeks depending on complexity and quantity, with expedited options available upon request. We also ensure compatibility with international shipping protocols, making delivery feasible to any region outside China and its territories.
