AWS A5.4 : E310
▶︎ Characteristics:
Heat resistance, corrosion resistance and toughness of LKE-310 are good. The weld metal is a full austenite structure containing 25%Cr-20%Ni. It is not necessary to preheat and postweld heat treatment.
▶︎ Applications:
It is suitable for the welding of dissimilar metals, low-temperature service stainless steel, mild steel and Cr-Mo steel.
▶︎ Notes on Usage:
1.Dry the electrodes at 200-250 °C for 60 minutes and keep at 100-150 °C before use.
2.Use lower currents for dissimilar metals welding. Keep the interpass temperature below 150 °C
3.The weld metal is a full austenite structure, which is easy to cause hot cracking
