描述
特点
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.
应用：
It is suitable for welding of stainless steel piping, boiler and gas turbine.
使用说明：
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.
