Metrode 2520LR description: 310L consumables are designed for welding special low-carbon 25%Cr-20%Ni alloys which are used for their excellent resistance to oxidising media, e.g. nitric acid. Applications range from the chemical process plant used in fertiliser production to the waste nuclear fuel reprocessing industries. It is not intended for welding standard type 310 used for heat resisting applications (see data sheet C-30). The electrode can also be used for surfacing steels to give a deposit with properties similar to the bulk weld metal, but care should be taken to deposit sufficient layers to eliminate any effects of dilution.
