ASTM B366 UNS N10675 LAP JOINT STUB END DN50 SCH10S 150# B16.9
STEEL SEAMLESS FITTING
We are one of the biggest manufactures of stainless steel & duplex
steel & alloy steel pipes/tubes, Fittings, Flanges in China. With
development more than 20 years, we have accumulated a great many
clients all around the world and Yuhong products also won the great
praise among the customers.
Scope
The specification of ASTM B366 covers wrought welding fittings for
pressure piping, factory-made from nickel and nickel alloys.
Threaded fittings as covered in ASME B16.11 are also covered by
this specification. The term welding applies to butt-welding or
socket-welding parts such as 45 and 90o elbows, 180o bends, caps,
tees, reducers, lap-joint stub ends, and other types, as covered by
ASME B16.9, ASME B16.11, ASME B16.28, MSS SP-43, MSS SP-95, and MSS
SP-97.

UNS N10675 is a nickel-molybdenum alloy with excellent resistance
to pitting, corrosion, and stress-corrosion cracking plus, thermal
stability superior to that of alloy B-2. In addition, this nickel
steel alloy has great resistance to knife-line and heat–affected
zone attack. Alloy B-3 also withstands sulfuric, acetic, formic and
phosphoric acids, and other non-oxidizing media. Furthermore, this
nickel alloy has excellent resistance to hydrochloric acid at all
concentrations and temperatures. Hastelloy B-3’s distinguishing
feature is its ability to maintain excellent ductility during
transient exposures to intermediate temperatures. Such exposures
are routinely experienced during heat treatments associated with
fabrication.
