Bailey of Sheffield jewellery lasts more than a lifetimehttp://www.outokumpu.com/en/stainless-news/cases/bailey-of-sheffield-jewelleryBailey of Sheffield jewellery lasts more than a lifetimeScott BaileyFounder, Bailey of SheffieldI liked the idea of being in Sheffield and manufacturing something out of stainless steel, because this is where the material originates from. The provenance has such a great heritage and a long history in making things.
Seven years strong with Fortahttp://www.outokumpu.com/en/stainless-news/cases/seven-years-strong-with-FortaSeven years strong with FortaSurry McFaulMetallurgical Engineer, Sun HydraulicsThe main reason we switched to Forta LDX 2101 was its tensile yield strength, which ranges from 65 to 124 ksi (kilopounds per square inch).
