AWS A5.5: E 8018-GH4R

EN ISO 2560-A: E 50 6 Mn1Ni B 32 H5

EN 10204 Type 3.1

Description

Basic coated stick electrode of high toughness and crack-resistance for high-strength fine-grained structural steels. Cryogenic down to -60 ^oC, and resistant to ageing. Approved for armour plates. Easily handled in all positions except for vertical down. Very low hydrogen content in the weld metal (under AWS conditions HD ≤ 4 ml/100g).

Coating: Lime coated (CaCO3, CaF2, FeMn, FeSi, Ni).

Category:Low Alloy Steel Groups
