With a proud tradition of steelmaking – the world’s first martensitic stainless steel was produced here more than 100 years ago – Sheffield is home to SMACC (Stainless Melting and Continuous Casting), wire rod mill ASR (Alloy Steel Rods) and bar finishing facility SSB (Sheffield Stainless Bar). In addition to long products units, Outokumpu has a coil and plate service center in Sheffield.

Sheffield Stainless Bar offers production flexibility, high quality and service unmatched within the industry. SSB specializes in smaller sizes of hexagon and square cold-drawn bar and cut-to-length rebar. The unit’s wide range of grades are designed for tailor-made applications. Even greater availability of unique product dimensions (special shapes and bars) is delivered through collaboration with a leading partner Böllinghaus Steel. SSB produces also Outokumpu’s Prodec bars offering superior machinability. These are sold through IMS group in the key European countries.

Rebar is produced in a wide range of dimensions and lengths, coils and bent shapes. The offering also includes dowel bar and complementary products. Strategically located stainless steel rebar stocks ensure high availability and short lead time.
