One of the most common forms of 2.4360 Monel 400 used in industries is a seamless pipe. The manufacturing process of these alloy 400 seamless pipes involves the following steps:
1. Raw Material Preparation: The production process starts with the preparation of the alloy 400 raw materials, which involves melting the required quantity of nickel, copper, and other alloying elements in a furnace.
2. Billet Production: Once the raw material is melted, it is poured into molds to produce billets, which are cylindrical in shape. The billets are then cooled and solidified.
3. Piercing: The solidified billets are cut into the required length, and their surface is cleaned. The clean billets are then heated to a specific temperature and pierced with a mandrel to form a Monel 400 hollow tube.
4. Hot/ Cold Rolling: The pierced tubes are then passed through a series of rollers to reduce their diameter and thickness. The ASTM B165 UNS N04400 tubes are rolled till the required dimensions are obtained.
5. Annealing: The Monel 400 hot cold rolled tubes are then annealed to improve their mechanical properties and eliminate any internal stresses caused by the rolling process.
6. Testing: The final step involves testing the Monel 400 seamless pipes for quality and compliance with ASTM B165, and B163.
