Our Ring Forging Process
Precision-controlled from billet selection to final inspection, our ring forging process ensures strength, accuracy, and superior structural integrity.
Raw Material Selection
High-grade slabs or billets are chosen based on mechanical properties, application requirements, and customer specifications.
Cutting & Heating
Billets are cut precisely and uniformly heated to achieve plasticity and eliminate internal stress before forging.
Forging
Hydraulic presses or ring-rolling machines shape heated billets into seamless forged rings with refined grain flow.
Ring Rolling & Shaping
Radial-axial rolling defines precise dimensions, enhances concentricity, and improves structural integrity for demanding performance needs.
Heat Treatment
Tailored heat treatments like normalizing or quenching improve hardness, toughness, and stress relief of forged rings.
Machining & Finishing
CNC machining achieves tight tolerances, while surface treatments enhance corrosion resistance and meet final specifications.
Inspection & Testing
Rings undergo dimensional checks, NDT, and material analysis to ensure compliance with quality and industry standards.
Available Materials
We provide carbon steel, alloy steel, stainless steel, titanium, nickel, aluminum alloys, and brass, ensuring strength, corrosion resistance, and application-specific ring forging performance.
Carbon Steel
Carbon steel is widely used in ring forging due to its strength, affordability, and excellent performance in structural and industrial applications.
Alloy Steel
Alloy steel provides enhanced hardness, wear resistance, and toughness, ideal for heavy-duty forged rings in automotive, power generation, and engineering sectors.
Stainless Steel
Highly corrosion-resistant and heat-tolerant, stainless steel is excellent for forged rings used in food, chemical, and marine environments.

Nondestructive Testing Methods for Forged Ring Quality
We use Nondestructive Examination (NDE) to ensure quality and reliability in all forged rings. It detects surface and internal defects without harming the parts. Our NDE methods include:
Visual Inspection (VT)
Conducted by certified inspectors to assess surface condition, geometry, and visible defects.
Radiographic Testing (RT)
Uses gamma or X-rays to examine internal structures and find inclusions, voids, or fissures that are hidden.
Ultrasonic Testing (UT)
Applies high-frequency sound waves to identify internal imperfections, such as inclusions and discontinuities, within the material.
Eddy Current Testing (ET)
Detects surface and just-below-the-surface cracks in conductive materials via electromagnetic induction without coming into direct contact with them.
Magnetic Particle Testing (MT)
Reveals surface and slightly subsurface flaws in ferromagnetic materials through magnetic fields and iron particle application.
Dye Penetrant Testing (PT)
Exposes surface-level cracks or defects using visible or fluorescent dyes, ideal for non-magnetic and non-ferrous materials.
