Inconel 625 Tube

ASTM B444 UNS N06625 Material and Alloy 625 Tubing Supplier in India

Inconel 625 tube

ASTM B444 UNS N06625 vs ASME SB 704 N06625

The ASTM B444 UNS N06625 Seamless Tube is mostly supplied in the annealed condition. They have many remarkable properties like good resistance to corrosion. They also show properties like good tensile strength and they have good creep resistance. These pipes are mostly available with seamless construction.

The ASTM B704 UNS N06625 Welded Tube is used for various high temperatures. They are found in heat exchangers, condensers, boilers and applications that expose the tube to a fluctuating temperature.
