Outokumpu Forta range duplex stainless steels offer excellent possibilities for the construction of challenging and durable structures. However, due to their high strength the forming process is somewhat different than with austenitic or ferritic steels. Outokumpu can assist you with all technical aspects of fabrication. We can provide you with the necessary training, computer simulations, and detailed instructions
Forta H400 and H500 are readily weldable with all conventional welding methods. No preheating or post-weld treatment is required. For applications in particularly critical conditions, temper colors or scaling should be removed chemically (for example, by pickling) and/or mechanically (for example, by grinding).
Temper rolled products
For temper-rolled austenitic stainless steels, the required forces and the elastic return are bigger compared with carbon steels. Because of their high ductility and strong work hardening, it is recommended to use sharp tools, effective cooling, and an adequate feed tool. Austenitic stainless steels in general have excellent weldability and are readily weldable with all conventional welding methods, including MMA, MIG, MAG, TIG, SAW, LBW and RSW, excluding gas welding.
