Incoloy 825 Pipe | ASTM B423 UNS N08825 Pipe Ex Stock

Q: What decides the Alloy 825 Round Pipe price per kg in India?

Nickel and molybdenum market prices on the quote date. Seamless or welded route, NPS and schedule. Quantity, cut lengths and certificate level.

Q: Which ASTM standards cover Nicrofer 4221 Welded Pipe and tube?

ASTM B423 for seamless pipe and tube. ASTM B705 for welded pipe and B704 for welded tube. ASTM B163 for seamless heat exchanger tube.

Q: Is Inconel 825 pipe the same as WNR 2.4858 Seamless Pipe?

Yes, both names point to UNS N08825 and W.Nr. 2.4858. Incoloy is the trademark family this alloy belongs to. Order it as ASTM B423 UNS N08825 to avoid confusion.

Q: What are the ASTM B423 mechanical properties of UNS N08825 Round Pipe?

Cold-worked annealed: 586 MPa tensile and 241 MPa yield min. Hot-finished annealed: 517 MPa tensile and 172 MPa yield min. Elongation 30% min in both conditions.

Q: Can Alloy 825 EFW Pipe be used in sour oil and gas service?

Yes, alloy 825 is listed in NACE MR0175 / ISO 15156-3. Supply in the annealed condition with UNS N08825 on the MTC. Environmental limits must be checked against the standard.

WNR 2.4858 Welded Pipe vs Inconel 625 vs SS 316L

Nickel and molybdenum separate these three pipe grades. Compare their specification ranges side by side here.

ASTM A312

SS 316L Pipe

Ni 10-14% and Mo 2-3%. Lowest cost of the three.

ASTM B423

Incoloy 825 Pipe

Ni 38-46% and Mo 2.5-3.5% with copper. Middle cost.

ASTM B444

Inconel 625 Pipe

Ni 58% min and Mo 8-10%. Highest cost of the three.

Verdict

Where 825 Fits

Pick 825 when 316L cracks in service. 625 often carries more alloy than needed.

South African acid plants often settle on 825. Cost ranking follows nickel and market prices.
