DAIKOWT 308LCF

The 308LCF product is used for welding austenitic stainless steels 18\/8, with operational service temperatures down to -196 °C. The components, including controlled ferrite electrodes for SMAW (Shielded Metal Arc Welding) and flux-cored wires, are specifically designed for cryogenic applications. Major applications include the welding of pipelines and tanks intended for cryogenic service, as in the case of liquefied natural gas (LNG). Preheating is not necessary, and the maximum allowable interpass temperature is 250 °C, while a temperature of 300 °C may be acceptable for thicker section materials. No post-weld heat treatment (PWHT) is required. To achieve optimal impact properties, it is recommended to operate at the upper extremes of the allowable heat input ranges.
