ASTM B407 pipe

What is ASTM B423 Pipe?

The ASTM B423 is a standard specification for pipes containing chromium and nickel in its alloy. It also has iron, molybdenum and copper of less amounts in its chemical composition. They are available in the form of hot-finished or cold-worked ASME SB 423 nickel chromium pipe solutions and are intended for use in general corrosive applications.

They offer great resistance to most corrosive environments, including chloride-ion related stress corrosion cracking. It also shows good resistance to reducing environments, like the ones having sulphuric and phosphoric acids in them. Adding molybdenum to the chemical composition also increases the resistance of the tube against pitting and crevice corrosion. The ASTM B423 Pipe is used in applications like nuclear fuel reprocessing, acid production, chemical processing, radioactive waste handling, etc.

What is ASME SB 423 Cold-Worked Pipe?

SB 423 Cold-Worked Pipe undergo a shaping process at ambient temperature, below their recrystallization temperature. The process involves using oil or water solutions for lubrication and cooling during the cold forming operation of SB 423 Material unheated pipes and tubes. This process is in contrast with various hot working techniques like hot rolling, welding, etc.

The cold worked pipes are in great demand due to their corrosion resistance properties. The material composition also helps it to show good resistance to different oxidizing agents, including nitric acids, nitrates, and oxidizing salts.
