Inconel wire is a nickel and chromium alloy wire offering excellent corrosion resistance suitable for operation in high temperatures. We supply nickel based alloy spring wire rolls, with sample qualification approval before bulk supply.
Pupular sizes: Spring wire 4mm, 5mm, 7.2mm, etc.
Inconel 600 Spring Wire
Inconel 600 spring wire is quality cold drawn wire made from a nickel base. It provides good corrosion resistance at operating temperatures up to 900°F.
Inconel 718 Spring Wire - Inconel 718 Nickel Alloy
For safty valve spring
GH-4169 Inconel Spring Wire
Wire diameter: 4.0 ± 0.04mm
Material Name: Inconel Spring Wire
Material Grade: GH4169
Product Condition: Solution Treated & Cold-Drawn
Manufacturing Conditions:
The ingots for fabricating the GH4169 alloy wires shall be melted by using vacuum induction and electroslag re-melted process.
The wires shall be performed solution treatment and then be cold-drawn, finally be delivered at the cold-drawn condition.
The recommended solution treatment is: maintaining at (950-1040)℃ for (0.5-1) hour, then water cooling.
The wires should be of coil shape and it should be in good order in the coil. The wires shall not become loose, twisted or ∞ shape while opening the wire coil.
There should be no scabs and weld joints.

Non-Destructive Testing:
The surface of wires shall be smooth and clean. There shall be free of defects such as cracks, hair folds, layers, spilliness, drawn marks, scars, grooves and pocks etc. on the surfaces. It's permitted for the existence of individual drawn marks and grooves with the depth not exceeding 0.03mm.
The surface roughness (Ra) of wires shall be equal to or less than 3.2μm.
Certifications:
All the requisite testing / processing certification to ensure that the material meets specification, but not less than mentioned certifications:
• Melting Method
• Heat Treatment Process
• Chemical Composition
• Dimensional Inspection
• Mechanical Property
• Metallographic Examination
• Surface Quality Inspection
• Results of Retest (if any)
Re-Examination:
In sampling tests, if the results of the specimens fail to meet the requirements for any item, double specimens shall be taken and retested for that item.
Lot will be rejected in case re-examination is not qualified.
Packaging & Delivery Conditions:
