Description
Characteristics:
LKT/LKM-347 is a niobium-bearing rutile electrode for Ti and Nb stabilized 18Cr-8Ni steels. Good inter-granular corrosion resistance and heat resistance can be obtained due to its Nb content. It is use for AISI 347, 321, 304L steels.
Applications:
It is suitable for welding of stainless steel piping, boiler and gas turbine.
Notes on Usage:
1. For TIG process, use DC(-) current , Argon Shield and Tungsten Electrode.
2. For MIG process, use Spray Transfer or Short Circuit Transfer mode.
3. 98%Argon – 2%O2 shielding gas is recommended in MIG process.
