ER 120 S-G High Tensile welding wire
AWS A5.28-96: ER 120 S-G
EN ISO16834-A G89 4 M Mn 4 Ni2.5 Cr Mo
Mild steel low alloyed Ni-Cr-Mo welding wire used for welding under protective gases. Preferred gas mix is Ar /Co2 , but can even be used with pure Co2 gas. This low alloy wire is manufactured to weld high strength steels with tensile strength higher than 900MPa. Excellent impact strength at low temperatures Suitable for the metal working industry, offshore fabrications, chemical and petrochemical industries. It has wide applications also in fabrication of HSLA ( high strength low alloy) used in industrial machineries constructions, cranes and other highly stressed structural components
Medium alloy solid wire electrode for shielded arc welding of quenched and tempered fine grained structural steels in crane and vehicle manufacturing. Good deformability in spite of very high strength values. Good resistance to cold cracking due to high purity of the wire surface.
