Lastifil 10020 TM is a closed and copper-plated metal cored wire for welding steels with high yield strength and tensile strength, such as S890QL, S960QL and S1100QL, HSLA, TMCP and QT steels.
The absence of slag allows for multi-layer welding without time-consuming slag snapping.
Excellent weldability, and beautiful weld appearance, practically spatter-free, with exceptional mechanical properties at low temperature (-40 °C).
Low hydrogen content (<5 ml / 100 g).
High strength steels for structures where the strength / weight ratio is very important.
Constructions subject to high stress, cranes, off-shore constructions, mobile constructions, ...
S890Q, S960Q, S890QL, S960QL, S1100QL.
Fine-grained high strength steel where low heat input is necessary to maintain the original properties.
Remove grease and impurities from the welding zone.
Respect pre-heating, interpass temperature and heat input depending on the base metal.
