Specification

AWS Specification: AWS A5.5 E8018-B2
JIS Specification: N/A
Other Specification: N/A

Description

N-8018-B2 is a basic coated low hydrogen welding electrode for welding of 1.25% Chromium and 0.5% Molybdenum alloy steels subjected to high pressure and temperatures, which are widely used in power plants and boiler piping
Specially formulated for the weld deposit to exhibit high tensile strength for strong weld joints and excellent charpy v-notch impact properties
Features quick striking technology to eliminate arc freeze and provides a seamless welding experience
Excellent welder appeal due to easy slag removal, easy maneuvering, quiet steady arc, and superb wetting properties

Application

Steam power generation equipment
Boiler pipes and heat exchanger steel tubes
Power plant industry
Chemical processing & oil refinery equipment

Remarks

Preheat at 200 - 250�C

Stress relieve at 620�C

Keep the arc as short as possible
