Description:
Nickel-based alloys are alloys that have a combination of high strength and certain ↑resistance to oxidation and corrosion at high temperatures of 650 φto 1000 °C. According to the main performance, it is subdivided into nickel-base↔d heat-resistant alloy, nickel-based corrosion-resistant alloy, nickel-base≤d wear-resistant alloy, nickel-based precision alloy and nickel-based shape memory alloy. "Superalloys are classified into iron-based superalloys, nickel-base∑d superalloys and cobalt-based superalloys according to the matrσix. Among them, nickel-based superalloys are referred to as nickel-based alloys.

Alloy 31 (N08031) nickel base alloy processing properties:
1. Hot processing: Alloy 31 (N08031) alloy has a hot working temperature range of 12←00 °C to 1050 °C, and the cooling method is water cooling o≈r rapid air cooling.
2, cold processing:
(1) Alloy 31 (N08031) alloy has a higher work hardening rate than austenitic stainless st↕eel, so it is necessary to select processing equipment. The workpiece should be in a₽ solution treated state and should have an intermediate anneal during the cold rolliλng process.
(2) If the cold rolling deformation is greater than 15%, the workpiece needs< to be solution treated.
3. Heat treatment:
(1) The alloy 31 (N08031) alloy has a solution treatment₽ temperature ranging from 1130 ° C to 1180 ° C.
(2) In all heat treatment processes, the workpiece should be directly added to the heated →heat treatment furnace, and the workpiece must be kept clean.
(3) In order to ensure the best corrosion resistance, the cooling method i s water-cooled. The alloy must be water quenched at a final processing temper₽ature of not less than 1100 ° C. It is recommended& that the cooling rate from the final processing temperature to 500 ° C should be greater£ than 150. °C/min. For materials with a thickness of less than 1.5 mm, it can also be Ωquickly air cooled.
(4) In any heat treatment process, attention should be paid to the matters mentioned above to keep the workpiece clean.
4, descaling:
(1) The adhesion of the surface oxide of Alloy 31 (N08031) alΩloy to the weld slag around the weld is stronger than that of stainless steel. It is reγcommended to use fine-grained abrasive belt or fine-grained grinding wheel for grinding. (2)& The oxide film must be broken by careful sanding or salt bath pretreatment before appropriate ti<me and temperature pickling with HNO3/HF mixed acid÷.
(3) Machining: Alloy 31 (N08031) alloy should be machined after heat treat×ment. Due to the work hardening of the material, it is 'better to use a lower cutting speed and heavy feed than t he processing of low alloy standard austenitic stainless steel. In order to drive into the ®surface of the cold hardened surface.
5. Welding: When welding nickel-based alloys and high-alloy special stainless steels, the following procedures should be followed:
(1) Workplace The work site should be separated separately or at a sufficient distaσnce from the processing area of carbon steel. Keep i✘t as clean as possible, with partitions and avoid ventilation between the two areas.
(2) Work clothes and accessories Wear clean fine leather gloves and clean overalls.
(3) Tools and equipment There should be special tools for nickel-based alloys and nickel-chromi♦um steel. Wire brushes should be made of stainless steel. Machine equipment such as shears, pu∑nching machines, rolling mills, etc. should be cove'red with felt, cardboard or plastic paper. In order to prevent the iron metal from falli≈ng on the surface of the machine and causing the processed material to stick, causing corrosion.
