Category: Avoiding Corrosion at Joints

  1. Welding stainless steels to other steels

    Welding austenitic stainless steels to carbon and low alloy steels are established methods in the process and construction industries. Over-alloyed fillers are used to avoid dilution of the parent stainless steel in the fusion zone. Filler type 308 can be used for joining a 304 type 'parent' to a carbon steel but more highly alloyed fillers, such as the 309 type are preferable. There should be no risk of post weld bimetallic ( galvanic) corrosion, if the joint is repainted.
