What is Inconel 625?
ASTM B444 is the standard specification for nickel-chromium alloy tubing, which consists of a nickel-chromium-molybdenum-niobium alloy. The main reason why these alloys are considered very useful in the manufacture of high quality tubing products is that it has high resistance to oxidation and corrosion and has a high melting point in both water and high temperature applications. The nickel based alloys are very ductile and therefore can be easily plated and welded, thus making them suitable for a variety of industries where extreme and harsh temperatures are important factors.ASTM B444 Seamless and ASTM B444 Seamless Tubing are suitable for use in aerospace industry piping systems, aviation jet engine exhaust systems, engine thrust reserve systems, specialized seawater equipment, chemical process equipment, etc.
