C1201 TUBE Nomal C1201T
  • The properties for enduring the pressure, bending, drawing, welding, corrosion, thermal, conductivity are excellent.
  • C1201 does not create hydrogen embrittlement when it is heated in the high temperature reduction environment.
  • C1201 is better then C1220 in electric conductivity
  • For heat exchanger, chemical industry, water supply, rapid boiling and gas pipes.
