Exaton 27.31.4.LCuR

The following items have been added to your list


Exaton 27.31.4.LCuR is a covered electrode of AWS E383-17 type with rutile coating and normal metal recovery for welding of high-alloy austenitic stainless steels of UNS S08028 (e.g. Sanicro 28) and Alloy 825 type (e.g. Sanicro 41). Exaton 27.31.4.LCuR is suitable for joining highly alloyed fully austenitic stainless steels, such as EN 1.4563 (Sanicro 28) and Alloy 825 (Sanicro 41), which have high corrosion resistance in sulphuric and phosphoric acids and excellent pitting resistance in acid solutions containing chlorides and fluorides, such as sea water. This electrode can be used for surfacing mild and low alloy steels to give protection against pitting corrosion in chloride-containing solutions. Because the product is a bit sensitive for forming hotcracks, a correct welding practice is important.
