Martensitic stainless steels have been widely used in the oil industry for Oil Country Tubular Goods (OCTG) over more than 25 years but have recently seen their field of use expanded by the development of "Super" 13%Cr alloys. This paper describes the design process and development of Super 13%Cr alloys in the United Kingdom to meet the oil and gas industry’s requirements while recognising the manufacturing constraints on the steelmaker and tubemaker. The mechanical properties and corrosion resistance are described.
