N-8016-B2

Specification

Description

• N-8016-B2 is a low hydrogen type electrode for all-position welding containing 1.25% Cr - 0.5% Mo

Application

• Welding of 1.25% Cr-0.5% Mo steel
• Super heater tube
• Steam pipes
• Headers of boilers for electric power plant
• Equipment for oil refining industry

Remarks

Dry the electrodes at 325-375ºC for about one hour before use

Preheat at 150 - 300ºC and postheat at 670 - 730ºC

Adopt back step method or strike the arc on a small steel plate to prevent blowholes at the arc starting

Keep the arc as short as possible
