A Brief History of Duplex Stainless Steel. The concept of duplex stainless alloys was discussed as early as the 1920s. However, production of the first duplex alloys did not begin until the 1930s. These earliest duplex alloys were mostly limited to cast production and specific uses as they contained a relatively high amount of carbon.
