説明
特徴
The weld metal of LKE-308L is a rutile electrode for welding low carbon 18Cr-8Ni stainless steel. LKE-308L contains low carbon to avoid carbide precipitation during welding.
アプリケーション
It is suitable for welding of stainless steel piping in refinery, oil and gas industries, and chemical plants.
使用上の注意
1.Dry the electrodes at 200-250°C for 60 minutes and keep at 100-150°C before use.
2.To make the cooling time as short as possible between 500-800°C to prevent the intergranular corrosion.
3.Clean up the slag with stainless steel brush to prevent impurity.
4.Use small heat input to reduce dilution, prevent cracking and improve impact value.
