MIG wire BOHLER UNION NiMoCr 1.0mm/18kg (17674)

MIG wire BÖHLER UNION NiMoCr 1.0 mm / 18 kg / ER100S-G / BS300 (17674)

BÖHLER UNION NiMoCr MIG wire is a copper-coated solid alloy welding wire designed for MAG welding of high-strength structural steels. It corresponds to classification EN ISO 16834-A: G 69 6 M21 Mn4Ni1,5CrMo and AWS A5.28: ER100S-G. Alloying with nickel, molybdenum, chromium, and manganese ensures high weld metal strength, good toughness, and resistance to mechanical stress.

The wire is primarily intended for welding quenched and tempered and thermo-mechanically rolled fine-grained structural steels with a yield strength of approximately 690 MPa. It is also suitable for joining selected wear-resistant and armour steels according to the welding procedure specification. The weld metal exhibits good toughness even at low temperatures, achieving a declared impact energy of 47 J at -60 °C when using M21 shielding gas.

BÖHLER UNION NiMoCr is used in the production of cranes, lifting equipment, construction machinery, transport technology, high-strength load-bearing structures and piping systems. It is suitable for welding S620Q, S620QL, S690Q, S690QL, S700MC steels and other compatible high-strength materials. Shielding gases of classes M21 and C1 are used for welding. The 1.0 mm diameter allows for good control of the weld pool when welding thin and medium-thickness steel parts. The wire is supplied on an 18 kg BS300 spool for professional and industrial use.
