ESAB OK Tigrod 13.38 2.0mm x 1000 5kg welding wire for stainless steel

Designed for use in heat-resistant steels and in hot hydrogen environments, particularly in oil refineries for GTAW welding. It is preferable to use it for 9% Cr steels, such as P 91/T 91 steels.

The alloy is modified in terms of impurity elements and is exceptionally "clean". This allows achieving better strength both in ambient and higher temperatures. The AWS organization has changed the classification of this product. The previous classification was A5.9 ER505.
