3. Core Products: Round Bars, Forgings, Seamless Tubes & Tube Blanks

1. Nickel Alloy & Superalloy Round Bars

   We produce solid round bars in different processing states: hot rolled, hot forged, cold drawn, solution annealed. Diameter range covers small precision bars to large heavy-diameter alloy bars, stable dimensional tolerance and uniform grain structure.

   

2. Alloy Forgings

   Custom open die forgings, closed die forgings, forged blocks, forged rings, forged shafts made from nickel superalloy ingots. We can machine forgings into semi-finished or finished parts per customer drawings.

   

3. Seamless Alloy Tubes & Ready Tube Blanks

   Abundant in-stock alloy tube blanks support short lead time orders. We process tube blanks into finished seamless tubes via piercing, hot rolling, cold drawing and heat treatment. Our seamless nickel alloy tubes feature high pressure resistance and high temperature oxidation resistance.

   

4. Complete Production & Inspection Workflow (Match Your Pictures: Melting-Ingot-Forging-Tube Rolling-NDT-Testing)

1. Vacuum Smelting Furnace Equipment

   Our vacuum induction melting & vacuum arc remelting furnaces control precise chemical composition of molten alloy, avoid impurity pollution, lay the foundation of stable material performance.

   
2. Alloy Steel Ingot Casting

   Molten alloy is cast into standard alloy ingots of different weights, uniform internal structure, no shrinkage cavity and segregation defects.

   

    

3. Heavy-Duty Forging Equipment & Forging Workshop

   Hydraulic forging press processes alloy ingots into forged billets, round bars, forged blocks and tube blanks. Hot forging optimizes metal flow and refines grain size.

   

4. Tube Piercing & Tube Rolling Machines

   Special seamless tube rolling units process alloy tube blanks into rough tubes and finished precision seamless tubes, control wall thickness tolerance accurately.

   

5. Non-Destructive Testing: Ultrasonic Inspection Equipment

   100% ultrasonic NDT inspection for all semi-finished and finished products to detect internal cracks, pores and inclusion defects inside alloy bars, forgings and tubes.

   

    

6. Finished Product Laboratory Testing

   Independent physical & chemical lab conducts full performance inspection: chemical composition analysis, tensile mechanical test, hardness test, grain size test, macrostructure (low magnification structure) inspection. All test reports can be provided together with goods.

   

5. Strict Quality Assurance Promise
