ASTM B407 SMLS UNS NO8810 Nickel Alloy Boiler Tubes
YUHONG Group offers ASTM B407 UNS NO8810 SMLS nickel alloy steel tubes and we sell these tubes in more than 70 countries up to now.
ASTM B407 This specification covers UNS N08120, UNS N08800, UNS N08801, UNS N08810, UNS N08811, UNS N08890, and UNS N06811 in the form of cold-worked and hot-finished annealed seamless pipe and tube. Alloys UNS N08800 and UNS N06811 are normally employed in service temperatures up to and including 1100°F (593°C). Alloys UNS N08120, UNS N08810, UNS N08811, and UNS N08890 are normally employed in service temperatures above 1100°F (593°C) where resistance to creep and rupture is required, and they are annealed to develop controlled grain size for optimum properties in this temperature range.
This page talk about the material NO 8810,Alloy NO8810 is a high-temperature nickel-iron-chromium alloy that offers excellent resistance to oxidation and corrosion.
