H08Mn2MoA, EA4 Submerged Arc Welding Wire

Description of H08Mn2MoA, EA4 Submerged Arc Welding Wire:
Compared with the common medium manganese and high-manganese steel welding wire, Mn-Mo steel welding seam is with higher weld metal strength, particularly in high temperature conditions, and also with better corrosion resistance.

Application of H08Mn2MoA, EA4 Submerged Arc Welding Wire:
It is commonly applicable for welding middle temperature pressure container steel structure lile 18MnM0Nb, and pipe-line steel welding such as X60,X65 etc.

Standard-compliant:

GB/T: H08Mn2MoA
