ASTM B407 Nickel Alloy UNS NO8800 Seamless Steel Tubes
ASTM B407 本规范涵盖 UNS N08120、UNS N08800、UNS N08801、UNS N08810、UNS N08811、UNS N08890 和 UNS N06811 冷加工和热加工退火管。
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.
同昌集团供应 ASTM B407 800 Nickel Alloy SMLS Tube in many years.
The Alloy 800 has good strength retention under exposure to extremely corrosive and high temperature environments along with having good creep and rupture strength.
They are widely used in chemical plants， refineries and power generation facilities， also are used in process piping， heat exchanger and furnace manufacture.
