Development history of duplex stainless steel

Early development of duplex stainless steel: Duplex stainless steel, which combines many beneficial properties of ferritic and austenitic stainless steels, was originally developed in the early 1930s. The initial duplex stainless steel provides good performance characteristics but has limitations under welding conditions. The metallurgical process at the time was not suitable for producing grades with the […]

What are the difficulties in the welding process of the duplex stainless steel 2205

There are some technological difficulties in the actual welding of duplex stainless steel 2205, but in fact, if we grasp 2205 of the related material characteristics, many problems will be solved when welding is processed. Here are the following aspects. First, compared with the first generation duplex stainless steel, 2205 has further increased the nitrogen content, […]
