描述
特性：
The weld metal of LKE-307 is a full austenite structure that contains 4-5% of Mn. With resistant to impact wearing and hot cracking.
應用：
It is suitable for welding of stainless cladding steel, high tensile steel and self-hardening alloy steels with poor weldability.
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.Clean up the slag with stainless steel brush to prevent impurity.
3.Use small heat input to reduce dilution, prevent cracking and improve impact value.
4.Keep the arc as short as possible.
