Description

FSA ChT A (ФСА ЧТ А) 650-20/80 is specially designed for the production of longitudinal and spiral welded pipes. The flux slightly dopes the weld metal with Si and Mn and operates equally well on both DC and AC. This flux provides small weld reinforcement when welding longitudinal pipe joints at high welding speeds.

FSA ChT A (ФСА ЧТ А) forms weld metal without solid inclusions due to the careful metallurgical calculation. It can be used to weld all types of pipe steels, up to the X100 strength class, providing high toughness values.
