Product Description
Inconel 718 Nickel Based Alloy Seamless Round Pipe
Product Information
Introduce
Inconel alloy is an Alloy-chromium alloy that combines corrosion resistance with high strength and good
fabricability. It has high creep-rupture strength at temperatures up to 700 ℃. Its excellent relaxation resistance contributes to its application in springs.
Application
The alloy is used in jet engine and high-speed airframe parts such as wheels, buckets and spacers, and high-temperature bolts and fasteners. Inconel alloy is also used in the oil and gas drilling and production industries due to its high strength and resistance to chlorides, stress corrosion and sulfide stress cracking. Within these industries the alloy has been used for valves, pump shafts and wellhead components.
Standards
Sheet, Coil and Plate: UNS N07718, AMS 5596, ASTM B 670, ASME SB 670, B50TF14,
Round Bar: UNS N07718, AMS 5662, ASTM B 637, B50TF15, B50809D (Power Generation)
other:AMS 5662, AMS 5663, AMS 5832, AMS 5962, ASTM B637, GE B14H89, ISO 15156-3, (NACE MR 0175)
Key Features
Good creep rupture strength at high temperatures
Higher strength
Better mechanical properties at lower temperatures
Age hardenable High temperature dynamic applications

Heat Treatments
Heat treatments may be adjusted to give required properties. For the best combination of tensile and stress rupture properties, the following quite complex cycle is recommended :
1 hr at 1750/1800ºF (955/980ºC) and air cool, then 8 hrs at 1325ºF (720ºC) and cool at 100ºF/hr (56ºC/hr) to 1150ºF (620ºC), hold for 8 hrs and air cool.
For the best room temperature and cryogenic tensile properties, the cycle is :
1-2hrs at 1950ºF (1065ºC) and air cool, then 8 hrs at 1325ºF (720ºC) and cool at 100ºF/hr (56ºC/hr) to 1150ºF (620ºC), hold for 8 hrs and air cool.
Hot Forming
Because of its strength, INCONEL alloy is more resistant than most materials to deformation during hot forming. It is readily hot-worked if sufficiently powerful equipment is used. Hot forming is performed in the 1650°-2050°F temperature range. In the last operation, the metal should be worked uniformly with a gradually decreasing temperature, finishing with some light reduction in the 1650°-1750°F range. This procedure is necessary to ensure notch ductility in stress-rupture applications when material has been annealed and aged.
Cold Forming
INCONEL alloy can be cold-formed by standard procedures used for steel and stainless steel.
Machining
INCONEL alloycan be readily machined, but its high strength and work-hardening characteristics must be considered in the selection and use of proper tool materials and design, operating speeds, and coolants. When machined in the age-hardened condition the alloy will have a slightly better finish; chip action on chipbreaker tools will be better. The use of annealed material, however, provides easier machining and longer tool life.
Super-Plastic Forming
This alloy, designated INCONEL alloy , is available as annealed sheet in thicknesses from 0.02 to 0.08 inches (0.5 to 2.0
mm) in widths up to 36 inches (914 mm). The specification SAE AMS 5950 was developed to define the requirements for the alloy.

FAQ
Q: Does this tubing come with triclamp ends to be coupled together?
A: This particular tubing comes without tri-clamp ends standard. We can always weld tri-clamp ferrules to the end of tubes for any specific length you need. These products are referred to as tri-clamp spool assemblies. If you need a specific length, please
contact us.
contact us.
Q: Are you able to cut tubing to lengths that don't require freight shipping? Say 5' lengths for example.?
A:Yes, we are able to cut down to other sizes. UPS Ground is able to ship up to 7' without the tubing being considered "oversized".We do charge a cutting fee for this service, however. Please contact us for a quote.
Q:How much does 1 stick of 4" tube weigh?
A: One 20' Stick of 4" Sanitary Tubing weighs approximately 75 pounds.
Q:You list gauge of this tubing at 16, but the wall thickness at 0.065". Isn't 16 gauge 0.0625"?
A: The wall thickness and gauges are all displayed in the table below. Please contact us if you have any other questions.
Q: Do you sell tubing in anything less than cases? I need to order just over 400 feet but don't want to pay for two cases as this is More than I need.
A: We do sell tubing on an individual basis however there is a $50 "broken box" fee applied to any order less than an entire case.Since we don't offer a way to order individual tube pieces online please call us to place an order over the phone.

Q: Do this product ship via freight?
A: Yes, our tubing comes in standard 20 foot lengths and will need to ship via freight. I'd also like to mention that there is a broken box charge meaning that if you do not order an entire box of tubing you will be charge additional fees as such. For more information please contact us. Thanks.
