NXF UNS N10276 2.4819/NiMo16Cr15W/C276 OD DN15-1200 Class 3000-9000 Nickel Alloy Forging Technology Socket Welding Olet
Super alloys have good oxidation and creep resistance and can be strengthened by precipitation hardening, solid-solution hardening and work hardening methods. They can also function under high mechanical stress and high temperatures and also in places that require high surface stability. HASTELLOY(r) C276 is a wrought corrosion-resistant alloy that resists the development of grain boundary precipitates that degrade corrosion resistance.
The following datasheet provides an overview of HASTELLOY(r) C276.

C276 Forging Technology Socket Welding Olet Product processing
1. Raw material selection and cutting
Select A105, stainless steel, and other forged round steel bars according to the working conditions. Verify the material quality certificate; calculate the cutting dimensions based on the specifications of the branch pipe seat, cut the blank material with a sawing machine, remove burrs, and ensure that the length and outer diameter tolerance of the blank material meet the standards.
2. High-temperature die forging
Send the blank material to the heating furnace to heat up to the forging temperature. Use a forging press to perform overall die forging, and forge out the main body of the conical part and the base shape of the socket groove at one time; perform normalizing / annealing heat treatment after forging to eliminate internal forging stress, refine the metal structure, and enhance the overall pressure-bearing strength and toughness.
3. Rough machining
Perform rough machining on the forging piece with a CNC lathe, machine the outer conical surface, the base plane of the seat, and the reserved processing allowance for the inner hole, correct the coaxiality, remove the forging oxide scale, and preliminarily shape the overall outline of the pipe fitting.
4. Fine machining
Perform secondary fine machining, precisely process the fitting's contact arc surface, the socket welding port of the branch pipe, and the inner and outer step bevels, strictly follow the ASME B16.11 standard to control the wall thickness, socket depth, and welding bevel size; complete mirror polishing to ensure that the welding contact surface is smooth without sand holes or scratches.
5. Marking, coding, and non-destructive testing
Laser / steel stamping mark the specifications, pressure rating, material, etc. according to the specifications; conduct magnetic particle / penetrant non-destructive testing to screen for forging processing defects such as cracks and pores, isolate and rework non-conforming products.
6. Surface protection and storage
Clean the processing oil stains and metal debris, spray anti-rust oil on carbon steel parts, and perform passivation treatment on stainless steel parts; recheck the dimensions and pressure rating, package them categorically, and store them for shipment.
