Welding of 18%Cr-8%Ni austenitic STS(AISI 304, 304L, 304LN, ASTM A157 Gr. C9; A320 Gr. B8C or D)
- K-308LT is designed for MAG welding of low carbon 18%Cr - 8%Ni stainless steel and used to joint austenitic stainless steel (AISI 304, 304L, 304LN, ASTM A157 Gr. C9; A320 Gr. B8C or D)
- The weld metal contains optimum ferrite contents in their austenitic structures, Therefore their weldability is excellent with lower crack susceptibility.
- It has easy slag removal, low spatter generation and good weld soundness of weld metal.
