Production and Processing Technology

TSM Technology employs advanced vacuum induction melting (VIM) followed by vacuum arc remelting (VAR) for superior Inconel 690 Wire alloy purity. Our wire drawing process utilizes precision dies and controlled atmosphere annealing to achieve consistent mechanical properties.

Cold drawing operations are performed in multiple passes with intermediate annealing treatments. This ensures optimal surface finish and dimensional accuracy while maintaining the alloy's microstructural integrity.

What is the production process of Inconel 690 Wire？

• Raw Material Preparation: High-purity nickel, chromium, and iron are carefully selected and analyzed for chemical composition compliance.
• Melting and Casting: Vacuum induction melting creates homogeneous alloy ingots with precise chemistry control.
• Hot Working: Initial breakdown of ingots through hot forging and rolling to achieve desired cross-sectional reduction.
• Wire Drawing: Multiple-pass cold drawing through precision carbide dies with intermediate annealing treatments.
• Final Processing: Surface cleaning, straightening, and quality inspection before packaging.
