Specifications

Alloy 59 (N06059) nickel-based alloy processing and heat treatment:
Alloy 59 (N06059) nickel-based alloys have excellent cold, hot work and machinability.
1, heating:
(1) Keep the workpiece clean and free of contamination before heat treatment and during heat treatment.
(2), can not contact sulfur, phosphorus, lead and other low melting point metals during the heat treatment, otherwise it will damage the performance of Alloy 59 (N06059) alloy, should pay attention to remove such as marking paint, temperature indicating paint, colored crayons, lubricating oil, Contaminants such as fuel.
(3) The lower the sulfur content in the fuel, the better, the sulfur content in natural gas should be less than 0.1%, and the sulfur content in heavy oil should be less than 0.5%.
(4) It is preferable to carry out heat treatment in a vacuum furnace or a gas protection furnace in consideration of temperature control and maintenance of cleaning.
(5) It can also be heated in a box furnace or a gas furnace, but the furnace gas must be clean and neutral to slightly oxidizing, and the furnace gas should be prevented from fluctuating between oxidizing and reducing properties. The heating flame cannot be directly Burn to the workpiece.
2, thermal processing:
(1) Alloy 59 (N06059) alloy has a hot working temperature range of 1180 ° C to 950 ° C. The cooling method is water cooling or rapid air cooling.
(2) In order to ensure the best anti-corrosion performance, heat treatment should be carried out after hot working, and the workpiece should be directly added to the heat-treated furnace.
3. Cold processing:
(1) Alloy 59 (N06059) alloy has a higher work hardening rate than austenitic stainless steel, so it is necessary to select processing equipment. The workpiece should be annealed and there should be an intermediate anneal during the cold rolling process.
(2) If the cold rolling deformation is greater than 15%, the workpiece needs to be solution treated.
4, heat treatment:
(1) The alloy solution temperature of Alloy 59 (N06059) alloy is in the range of 1100 ° C to 1180 ° C.
(2) For materials with a thickness less than 1.5mm, it is recommended to use water cooling or rapid air cooling to ensure the best corrosion resistance.
(3) In all heat treatment processes, the workpiece should be directly added to the heated heat treatment furnace, and the workpiece must be kept clean.
5, descaling:
(1) The adhesion of the surface oxide of Alloy 59 (N06059) alloy to the weld slag around the weld is stronger than that of stainless steel. It is recommended 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 the appropriate time and temperature pickling with HNO3/HF mixed acid.
6. Machining: Alloy 59 (N06059) alloy should be machined after heat treatment. Due to the work hardening of the material, it is better to use a lower cutting speed and heavy feed knife for processing low alloy standard austenitic stainless steel. Under the surface of the cold hardened surface.
7. Recommendations for welding: When welding nickel-based materials, the following procedures should be followed:
(1) Workplace The work site should be separated separately or at a sufficient distance from the processing area of carbon steel. Keep it 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-chromium steel. Wire brushes should be made of stainless steel. Machine equipment such as shears, punching machines, rolling mills, etc. should be covered with felt, cardboard or plastic paper. In order to prevent the iron metal from falling on the surface of the machine and causing the processed material to stick, causing corrosion.
8. Cleaning: The material to be welded should be in solution treatment state, remove oxide scale, oil stain and various mark marks, and clean the base metal and filler alloy (such as welding rod) of the welding area with acetone. Note that trichloroethylene cannot be used. TRI, perchloroethylene PER and tetrachloride TETRA.
9. Edge preparation: It is best to use machining, such as turning, milling, planing, and plasma cutting. If the latter is used, the cutting edge (welding surface) must be ground and smooth, allowing for hot grinding.
10. Groove angle: Compared with carbon steel, the physical properties of nickel-based alloys and special stainless steels are mainly low thermal conductivity and high expansion coefficient. These characteristics should be considered in the preparation of welding groove, including Wide bottom clearance (1 ~ 3mm), due to the viscosity of the molten metal, a larger groove angle (60 ~ 70 °) should be used in butt welding to offset the shrinkage of the material.
11. Arcing: Arc should be started in the welding area of the workpiece, that is, arcing on the welding surface to prevent corrosion caused by the arcing point.
12, welding process: Alloy 59 (N06059) alloy can be welded with the same material or other metals, suitable for welding by any traditional welding process, such as tungsten electrode inert gas shielded welding, plasma arc welding, manual sub-arc welding, metal inert gas Protective welding, melting inert gas shielded welding, pulse sub-arc welding technology is preferred. When using manual arc welding, it is recommended to use a mixed shielding gas of Ar+He+H2+CO2.
13. Filler metal: For gas shielded welding, it is recommended to use the same electrode with the same chemical composition as the substrate. Commonly used welding wire: ERNiCrMo-13 coated electrode: ENiCrMo-13.
