Atom Arc 7018-B2L

Atom Arc 7018-B2L is a 1 1/4 Cr - 1/2 Mo electrode with extra low carbon content. The low carbon content in the weld metal is beneficial in reducing cracking of weldments. Atom Arc 7018-B2L is carefully engineered to produce a stable arc and good slag release when welding low-alloy steels in the categories of 1/2% Cr - 1/2% Mo, 1% Cr - 1/2% Mo, 1 1/4% Cr - 1/2% Mo steels. Most grades of these steels are used in power piping, boiler work, castings and forgings.
