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.
