Low-alloy steels Manual electrode E9016-B3 Seal materials
Low hydrogen potassium type hand electrode, under 550C high temperature working conditions still has excellent creep resistance
Stable arc, less splash, good molding, easy slag removal, X-Ray performance
Under special heat treatment conditions, stable low temperature impact performance can still be guaranteed.
