Chemical Properties of Monel 400
Ni | Cu | Al | Ti | C | Mn | Fe | S | Si |
63.0-70.0 | 27-33 | 2.30-3.15 | 0.35-0.85 | 0.25 max | 1.5 max | 2.0 max | 0.01 max | 0.50 max |
1. Raw Material Selection: The first step in producing Monel 400 wire is selecting high-quality nickel and copper as raw materials. These raw materials must meet stringent quality standards to ensure the final product has excellent performance.
2. Alloy Melting: The selected nickel and copper raw materials are mixed in specific proportions and melted at high temperatures to produce Monel 400 alloy. During the melting process, temperature and composition must be strictly controlled to ensure the quality and stability of the alloy.
3. Billet Preparation: The melted Monel 400 alloy is cast into appropriate-sized billets, typically round or square in shape.
4. Billet Heat Treatment: The billets undergo heat treatment to relieve internal stresses and improve the material's mechanical properties. This step is crucial to ensuring the quality of the final wire.
5. Drawing Process: The heat-treated billets are fed into drawing machines, where they are gradually reduced in diameter through continuous drawing to produce Monel 400 wire of the desired diameter and gauge.
6. Surface Treatment: The Monel 400 wire, after drawing, undergoes surface treatments such as pickling, polishing, etc., to improve surface quality and smoothness.
7. Testing and Packaging: The produced Monel 400 wire undergoes rigorous quality testing to ensure it meets customer requirements and standards. It is then packaged and labeled for shipment to customers.
