Alloy 625 Seamless Pipe
Alloy 625 seamless pipe is a high performance nickel alloy material, also known as ASTM B444 UNS N06625 alloy pipe.
It adds molybdenum and more chromium than alloy 600 seamless pipe. This gives it better corrosion resistance. At the same time, 625 added niobium to increase the effect of solid solution strengthening. This gives it more strength
625 has high strength, which makes the cold rolling process of seamless pipe more difficult. Seather have a complete seamless pipe production line, which can fully guarantee the quality of finished pipes.
Our alloy 625 pipes are produced strictly to the default ASTM B444 standard. In addition, we do a complete hydrostatic test on nickel alloys pipes.
