ASTM B517 Pipe specification
Identify suppliers of ASME sb517 welded nickel-chromium-iron-alloy pipe in UAE and compare ASTM b517 vs b725
ASTM B517 vs B725
ASTM B517 and B725 are high nickel-content alloy specifications with many similar properties. A few of the common properties between them include high strength and corrosion resistance, But there are also many differences between the ASTM B517 and B725 because of varying element composition. A few of the differences include the following among others.
- Two alloys of B725 UNS N02200 and N02201 have nickel over 99% as aircraft materials and are expensive but have superior strength and corrosion resistance.
- Compared to that B517 specification alloy UNS N06600 has up to 72% nickel whereas the other UNS N06603, N06025, and N06045 have lesser nickel of around 50 to 60%

What is ASTM B517’s specification?
There are four nickel-chromium-iron alloys in welded, annealed and cold-worked condition covered by the ASTM B517 specification. Though they have different nickel, chromium and other element composition, all of them are useful for heat-resisting and general corrosive service applications.
The ASTM B517 specification also covers the OD or outside diameter and nominal wall thickness. It should also fulfil the ANSI B36.19 requirements. Any other specific diameter need of the customer should comply with all the other ASTM B517 specifications. The lines under the specifications include UNS N06600, N06603, N06025, and N06045.
You may find Dubai-based stockists of Schedules 40, 80, 20, 60, std, and XXS ASTM b517 tubing in bespoke diameters here. Furthermore, observe how it is cold worked.
How does ASTM B517 weld pipe be cold worked?
Cold working of ASTM B517 welded pipe enhances the quality, performance, corrosion resistance, and dimensional flexibility. ASTM B517 specifications mandate cold-working for ASTM B517 tubing before conducting a final heat treatment.
Cold working of ASTM B517-19 welded pipe is by using either the weld metal or the weld and the base metal. All four major cold working processes are suitable for B517 pipe-making to provide optimal performance.

What are ASTM B517 pipe grades?
There are four ASTM B517 pipe grades with varying quantities of nickel. All of them are Inconel superalloys with high nickel content and other elements. The four grades of alloys covered by ASTM B517 specifications include the following.
- UNS N06600 is the Inconel 600 alloy to have nickel up to 72%, 14 to 17% chromium, iron 6 to 10% and in small quantities of manganese, copper, carbon, silicon and sulfur
- UNS N06603 have a high carbon content of 20 to 40%, chromium 24 to 26%, iron 8 to 11%, aluminium 2 to 4% and remaining nickel and small quantities of other elements
- UNS N06025 and N06045 also have high nickel, chromium and other elements.
Trash is not something you have to pay for! Cut-to-length services are frequently provided by ASME sb 517 pipe distributors and traders here. verify the automatic welding procedure.
What is the automatic welding process performed on ASME SB 517 pipe?
Each ASTM B517 welded nickel-chromium-iron-alloy pipe undergoes an automatic welding process. Inconel alloy sheets are put through rollers to form lines and tubes of desired sizes. The flat-rolled Inconel alloys undergo an automated process requiring no filler metal additions.
ASME SB 517 pipe also undergoes cold working after welding to ensure optimum corrosion resistance.
Also, a final heat treatment in the base metal and weld area increases its strength and withstanding capacities against high temperature and pressure.
