Stainless to Carbon Steel Welding

Stainless-to-carbon steel joints appear in equipment repair, transition sections, structural attachments and process piping supports.

The application is usually selected for function, cost control or combining corrosion resistance with carbon steel structure.

Dissimilar metals create dilution and cracking considerations that require a suitable buffer or joining consumable.

The final choice depends on base material grades, joint design, operating temperature and service environment.

E309L-16 for many stainless-to-carbon steel joining applications.

E312-16 may be considered for difficult weldability situations or repair applications requiring higher crack resistance.

E309L is commonly used as a transition consumable between stainless steel and carbon steel.

E312 is positioned for more demanding repair and dissimilar metal welding applications where weldability margin is important.
