Alloy 718 · UNS N07718
An Inconel 718 cross is a four-way fitting with branches at 90°, made from Inconel 718 to Machined from B637 on request (buttweld) · ASTM B637 (forged). Crosses join four pipes in one fitting. They are used less than tees because of stress concentration, but save space in fire-water and utility systems.

Why are crosses less common than tees?
They concentrate stress at four junctions; most designers use two tees unless space is critical.
Which standard covers Inconel 718 crosss?
The material is Machined from B637 on request (buttweld) · ASTM B637 (forged); dimensions follow ASME B16.9 · B16.11. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a Inconel 718 cross?
The alloy price, the size and schedule or class, quantity, and the testing and documents required. Send your list and we quote the same working day.
Can you supply Inconel 718 crosss to NACE MR0175?
Yes. Inconel 718 is listed in NACE MR0175 / ISO 15156-3 within its limits; state NACE compliance on the order and it is confirmed on the certificate.
What documents do you supply?
EN 10204 3.1 mill certificates as standard, 3.2 with third-party inspection on request, plus dimensional and PMI reports.
