Outokumpu Stainless Ltd is one of the world's largest manufacturers of stainless steel strip, plate and rod. It was previously known as Avesta Stainless Ltd.
The company's Sheffield rod mill rolls wire in a variety of alloys and diameters. In 1995 the company embarked on a modernisation programme, integral to which was the addition of wire pickling and annealing facilities, allowing it to supply bright-annealed rod to its clients.
The pickling project involved a fully automatic immersion process line for handling 1.5 tonne loads of coiled stainless steel wire in a mixture of sulphuric acid, hydrofluoric acid and hydrogen peroxide, together with rinsing and high-pressure washing.
To serve this plant, bulk chemical storage and dosing systems, fume scrubbing and effluent treatment systems were also included.

We still provide long-term service and technical support to the client and the plant itself is still working efficiently.
