Stainless Steel Electrodes LKE-347

Characteristics:

LKT-347 is a niobium-bearing rutile electrode for Ti and Nb stabilized 18Cr-8Ni steels. Good intergranular 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.Dry the electrodes at 200-250oC for 60 minutes and keep at 100-150oC before use.
2.Use lower currents and keep the arc as short as possible
