ASTM B514 NO8810 Incoloy 800H Welded Nickel Alloy Boiler Tubes
YUHONG Group offers ASTM B514 UNS NO8810 welded nickel alloy steel tubes.
ASTM B514 This specification covers nickel-iron-chromium alloys in the form of welded, cold-worked, and annealed pipe for general corrosive service and heat-resisting applications. These products are furnished in three alloys: UNS N08120, UNS N08800, and UNS N08810. Alloy UNS N08800 is employed normally in service temperatures up to and including 1100°F (593°C). Alloys UNS N08120 and UNS N08810 are employed normally in service temperatures above 1100°F where resistance to creep and rupture is required, and are annealed to develop controlled grain size for optimum properties in this temperature range.
This page talk about the material Incoloy 800H,Alloy NO8810 offers excellent resistance to oxidation and corrosion, with best joined/welded using products for high temperature situations, resistance to prolonged exposure to elevated temperatures and it has many other characteristics.
