Applications and Features

( 1 ) KMS-62 is 74%Ni-16%Cr-8%Fe-2%Nb alloy.

( 2 ) The addition of Nb is to avoid the stress induced cracking of heavy plate .

( 3 ) Suitable for welding Inconel 600, Incoloy 80, ASTM B163, B166,B167 and B168 Ni-Cr-Fe alloy.

( 4 ) Ideal for welding offshore, LNG, pressure vessel and chemical equipment.

Welding Position

Welding Instruction

( 1 ) Clean surface of base metal before welding.

( 2 ) Heat input should be controlled as low as possible.  

( 3 ) For other instructions, please refer to Appendix B.
