Covered Electrodes ESAB OK 63.31 316LSi 1.4430

ESAB OK 63.31 Coated Electrode

CrNi and CrNiMo Steels

• Self-releasing slag
• Highest ESAB quality
• Can be used up to 400 °C
• Low spatter formation

Austenitic, core-alloyed coated electrode with excellent welding properties, suitable for many applications. Features low delta ferrite content for chemical applications and shipbuilding. Mostly used for similar unstabilized CrNi and CrNiMo steels. However, the electrode can also be used for titanium- or niobium-stabilized CrNi and CrNiMo steels up to 400 °C. Easy to handle, even for inexperienced welders. Minimal spatter formation and self-releasing slag.

Pleasant welding behavior. Good ignition and re-ignition.
