ASTM B163 UNS NO8825 Nickel Iron Chromium Alloy Seamless Pipe
We are one of the biggest manufactures of stainless steel & duplex
steel & alloy steel tubes and pipes 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.
ASME B163 covers seamless tubes of nickel and nickel alloy for use
in condenser and heat-exchanger service. This covers outside
diameter and average wall, or outside diameter and minimum wall
tube. Tube shall be furnished in the alloys and conditions defined
by this specification. The material shall conform to the
composition limits of nickel, copper, molybdenum, iron, manganese,
carbon, silicon, chromium, aluminium, titanium, phosphorus, cerium,
zirconium, yttrium, born, cobalt, columblum, tungsten, and nitrogen
specified. Tensile strength, yield strength, elongation, and
Rockwell hardness of the material shall conform to the required
mechanical properties set by this specification. Test methods such
as chemical analysis, tension, rounding procedure, Rockwell
hardness, grain size and hardness conversion shall be performed.
SB163 SB423 N08825 Nickel Alloy Seamless Tubes Tubing Pipes is a
nickel-iron-chromium alloy with additions of molybdenum and copper.
This nickel steel alloy’s chemical composition is designed to
provide exceptional resistance to many corrosive environments. It
is similar to alloy 800 but has improved resistance to aqueous
corrosion. It has excellent resistance to both reducing and
oxidizing acids, to stress-corrosion cracking, and to localized
attack such as pitting and crevice corrosion. Alloy 825 Incoloy 825
is especially resistant to sulfuric acids and phosphoric acids.
This nickel steel alloy is used for chemical processing,
pollution-control equipment, oil and gas well piping, nuclear fuel
reprocessing, acid production, and pickling equipment.
