Metrode Ultramet-B308LCF description: Used to weld 18/8 stainless steels with service temperatures down to –196°C. The controlled ferrite SMAW electrodes and flux cored wires are specifically designed for cryogenic service; they are not batch selected consumables. Applications include pipework and vessels subject to cryogenic service (-196°C) eg LNG. Standard 308L consumables for general purpose fabrication can be found in data sheet B-30. The 308L consumables covered here are not suitable for 304/304H in elevated temperature structural applications, see data sheets C-10 and C-12.
