描述
特性：
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.
應用：
It is suitable for welding of stainless steel piping, boiler and gas turbine.
使用注意事項：
1.Dry the electrodes at 200-250 °C for 60 minutes and keep at 100-150 °C before use.
2.Use lower currents and keep the arc as short as possible
