Product Forms
Round Bars: Φ12–Φ850mm, straight/cut-to-length, polished/black finish
Forgings: Custom-shaped rings, discs, shafts, and blocks via free forging or die forging
Seamless Tubes: Outer diameter 4–300mm, wall thickness 0.2–30mm, cold-drawn/hot-rolled
Tube Billets: In-stock for immediate processing, reducing lead times significantly

Advanced Production & Quality Control
Our one-stop production workflow spans from vacuum steelmaking to finished product testing, ensuring full process traceability and quality consistency

1. Steelmaking & Ingot Casting
Vacuum Induction Melting (VIM) and Electroslag Remelting (ESR) for high-purity alloy ingots
Precise chemical composition control to meet international standards (ASTM, UNS, DIN)

2. Forging Processing
Hydraulic forging presses for open-die and closed-die forging
Controlled heating and cooling to optimize grain structure and mechanical properties

3. Tube Production
Piercing mills and cold-drawing lines for seamless tube manufacturing
Precision sizing and surface treatment for tight tolerance requirements

4. Rigorous Quality Assurance
We implement 100% inspection for all products, covering:
Ultrasonic Testing (UT) and Non-Destructive Testing (NDT) to detect internal defects
Mechanical property tests (tensile, hardness, impact)
Grain size analysis and macrostructure examination
Chemical composition verification via spectrometer
