ASTM B444

Inconel 625 Seamless Pipe and Tube.

ASTM B444 Standards And Specifications

ASTM B444 Specification covers Inconel 625 in the form of cold-worked seamless pipe and tube.

ASTM B444 Seamless Pipe and Tube

ASTM B444 pipe and tube

ASTM B444 Seamless Pipe and tube are composed of Nickel-Chromium-Molybdenum-Columbium based alloys. These alloys are very useful for the manufacturing of high quality tubing products. One of the key reasons is that they offer excellent corrosion resistance in both aqueous and high temperature applications. In addition to their high melting points and resistance to oxidation and corrosion, nickel alloys are very ductile. They can be electroplated and are easily welded, making them suitable for use in industries where very high and low temperatures come into play. Seamless Pipes and tubes are used in Aircraft Ducting System, Aerospace, Jet Engine Exhaust systems, Engine Thrust Reserver systems, Specialized Seawater equipment, Chemical Process equipments etc.

Scope And Manufacturing

ASTM B444 specification is for Inconel 625 Seamless Pipe and Tube. UNS N06625 products are furnished in annealed Grade 1 and solution annealed Grade 2. Chemical testing shall be performed on each type of material and shall conform to the chemical composition limits specified for carbon, manganese, silicon, phosphorus, sulfur, chromium, tantalum, columbium, cobalt, molybdenum, iron, aluminum, titanium, copper, and nickel. The material shall undergo tensile testing and shall conform to the required room temperature tensile properties like tensile strength, yield strength, and elongation depending on the heat treatment used and including small diameter and light-walled tubing. Each pipe or tube shall undergo hydrostatic testing and shall conform to the allowable fiber stress and also be examined with a nondestructive electric test as prescribed.
