316LCF

These consumables are specifically designed for use with austenitic stainless steels containing a molybdenum (Mo) percentage between 1.5% and 3%. Among these, 316/316L steels are widely recognized for their excellent pitting resistance, along with providing significant protection against many acids and general corrosion. Electrodes with controlled ferrite for SMAW welding and cored wires have been specifically designed to operate under cryogenic service conditions. Typical applications include pipelines and vessels intended to operate at cryogenic temperatures (-196 °C), such as in the case of liquefied natural gas (LNG). These materials are not suitable for 316/316H steels intended for high-temperature structural applications. No preheating is necessary, and the maximum interpass temperature can reach 250 °C (up to 300 °C on thicker section materials). No post-weld heat treatment (PWHT) is required. To ensure optimal impact properties, it is recommended to apply heat inputs at the upper limit of the allowed ranges.
