316LCF

These welding consumables are employed for Mo-bearing austenitic stainless steels containing 1.5-3% Mo, notably used with Type 316/316L steels known for their robust resistance to pitting, various acids, and general corrosion. Specifically designed as controlled ferrite shielded metal arc welding (SMAW) electrodes and flux-cored wires, these consumables are tailored for applications in cryogenic service. Common uses include pipework and vessels subjected to cryogenic conditions, such as LNG facilities. It's important to note their inappropriateness for elevated temperature structural applications involving 316/316H. Operating guidelines dictate no preheating requirement, a recommended maximum interpass temperature of 250°C (with 300°C potentially acceptable for thicker sections), and no post-weld heat treatment (PWHT) necessity. To optimize impact properties, it is advised to apply heat inputs at the higher end of the allowable ranges during the welding process.
