ASTM B407 NO8810 800H Nickel Alloy Seamless Steel Tube
YuHong Group supplies ASTM B407 800H Nickel Alloy SMLS Tube, the tubeis a a nickel-molybdenum-chromium superalloy with an addition of tungsten designed to have excellent corrosion resistance in a wide range of severe environments. This nickel alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process application in an as welded condition.
The Alloy 800H series of alloys offer good strength retention under exposure to extremely corrosive and high temperature environments along with having good creep and rupture strength. They have found wide usage in chemical plants, refineries and power generation facilities.And suitable applications are found in process piping, heat exchanger and furnace manufacture.
