DW-A55LSR is a rutile flux cored wire whose weld metal tolerates post weld heat treatment (PWHT) without an adverse degradation of mechanical properties.
DW-A55LSR produces a nominal 0.9%Ni weld metal which means that it fulfills NACE requirements for oil and gas production equipment in sour gas service.
These properties make for a varied range of usages in pipeline construction and offshore applications.
