🏭 Manufacturing Process
Producing a Nickel 200 Round Bar requires precision engineering and stringent quality control:
-
Raw Material Selection – Only certified high-purity nickel ingots are used.
-
Hot Working – Bars are formed through hot rolling or extrusion for optimal grain structure.
-
Cold Drawing – Achieves the required diameter tolerance and surface finish.
-
Annealing – Improves ductility and corrosion resistance.
-
Surface Finishing – Polished or turned to meet customer specifications.
-
Final Inspection – Includes dimensional checks, ultrasonic testing, and chemical analysis.
