The History of Duplex Stainless Steel

Early Duplex Development: Duplex stainless steels, which combine many of the beneficial properties of ferritic and austenitic steels, were originally developed in the early 1930′s. The initial duplex grades provided good performance characteristics, but had limitations in the as-welded condition. The metallurgical processes at that time were not suitable for producing grades with the right  Continue Reading →


The History of Stainless Steel

Early Stainless Steel Development: The development of stainless steel occurred over about a 100 year time period, and was based on the accomplishments of numerous individuals. In 1821, Pierre Berthier, a French Metallurgist, discovered that iron-chromium alloys were resistant to some acids.
