Analysis of the characteristics of third generation duplex stainless steel

The first generation of duplex stainless steel is 3re60 in the 1960s, which has the problem of welding thermal zone. The second generation was developed in the late 1970s with ultra-low carbon and nitrogen bearing characteristics, the typical number was 2205, and the steel’s pitting equivalent index was 32-39. The third generation is ultra-low carbon, high molybdenum […]
