Low alloy Mn Mo MIG wire.
Applications
Fabrication of higher strength steels for use in the stress relieved condition. For offshore oil well-head process pipework and fittings, these low nickel consumables satisfy NACE MR0175 requirements intended to ensure resistance to sulphide-induced stress corrosion cracking in sour service, combined with good sub-zero toughness. Also finds applications for the repair of medium strength low alloy steel castings where a stress-relief only (rather than N+T) is to be applied.
