Basic 316L cryogenic pipe welding MMA electrode – designed and manufactured to give high moisture resistance using a basic flux system and high-purity 304L core wire. Ultramet B316L is particularly suited to the most demanding vertical and overhead welding applications including fixed pipework in the ASME 5G/6G position. Under site conditions, it is tolerant to adverse wind and drafts. Recovery is about 110% with respect to the core wire, and 65% with respect to the whole electrode.
Applications
These consumables are used for Mo bearing austenitic stainless steels with 1.5 – 3% Mo. Type 316/316L steels are widely used for their good resistance to pitting, many acids and general corrosion. 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.
