WR-Steel®, which stands for wear resistant steel, includes a broad range of grades with a wide range of hardness levels, dimensions and steel grades designed to give you a wear-resistant advantage when making products exposed to a high degree of wear and where service life is important. The whole idea is to combine cost efficiency at the manufacturing stage with just the right wear resistance in your end product. The WR-Steel mission is to optimize the wear resistance of your products and, at the manufacturing stage, give you the flexibility you want to be able to form, shape and weld the steel to fit your engineering needs precisely. With three main metallurgies of billets, blooms and ingots, the WR-Steel product range is the broadest of its kind in Europe and includes more than 30 different types of boron steel and special grades for mining applications

Rolled and forged rings by Ovako reduce your need for further machining and associated maintenance costs and material waste, with longer lifespans and higher wear and corrosion resistance. As a result of our quality control, manufacturers can simplify their production processes and reduce their costs because the rings are not only predictably consistent from batch to batch, but also easy to process further. Ovako produces profiled rings with very small allowances and tight tolerances close to the final shape of the end product. In addition, our machined rings enable you to concentrate resources on finishing andor assembly. The dimensional range is 170–4000 mm and the weight range is 7–5000 kg. Forged rings are also supplied up to 3400 kg. Furthermore, Ovako can offer shot blasted rings of diameters up to 4000 mm and weights up to 5000 kg

M-steel is a low alloyed, or non-alloyed, m-treated steel that is the ultimate choice when you need superior machinability combined with exceptional toughness and fatigue strength. It has proven its ability to achieve significant reductions in machining costs for component manufacturers which have replaced conventional steel with m-steel. M-steel enables higher cutting speeds and improved efficiency. Tests show that m-steel can reduce machining costs by 30–40%, significantly boosting profitability. The m-steel concept our m-steel treatment can be applied to any steel grade. The basis for the concept is that non-metallic inclusions are modified and controlled with calcium treatment. These inclusions are modified in a way to maximize machinability and to improve transverse fatigue strength. In this way, a protective layer is formed on the cutting tool during machining that very significantly reduces the wear on the tool and increases tool life. At every stage of the m-steel production process the material is optimized to improve machinability, from raw material through melt, to casting, hot rolling and the final heat treatment. Individual delivery requirements can be met to supply your material in the best form for your machines in compliance with tight straightness and dimensional tolerances. M-steel has a consistent machinability from cast to cast, meaning that machines can be run with fixed high cutting rates and predictable tool change intervals from one production run to another.

Bq-steel is a bearing quality clean steel that has been optimized for fatigue strength by a strict control of steel cleanliness. Bq-steel is also ideal for new design solutions in a wide array of demanding applications outside the bearing industry that require longer performance and higher loads. The extended performance, higher loads and high cleanliness of bq-steel are a result of the ovako clean steel program. Purity of production means that the material has significantly smaller inclusions compared to conventional steel and, as a result, the fatigue strength of the steel is increased dramatically. Use of the material allows components to be manufactured in smaller sizes. Component downsizing and increased loading are both issues facing manufacturers today as space restrictions and lower operating weight are driven by energy conservation. Ovako’s new generation of bearing quality steel, bq-steel, is optimised and well-proven in applications where fatigue strength is critical, allowing component manufacturers to rethink their design solutions. High strength through hardening and high fatigue resistance through steel cleanliness facilitate the manufacture of components to meet the requirements of today and tomorrow. This is true for a wide range of industries where high cyclical loading is an issue.

Flat bars by Ovako combines precisely controlled manufacturing processes for superior impact toughness, good surfaces and high yield strength across a range of applications. Ovako delivers hot-rolled flat bars in a broad dimension range. The bars are characterised by excellent straightness and shape as well as good surfaces and low decarburisation. Straightness The out of straightness is measured and our flat bars comply with European Standard EN 10058 as-rolled, but can also be delivered in the as-straightened condition. Shape and dimensions The rolled shape is generally flat bars with square corner edges. It can on request also be rolled as flat bars with different corner radiuses. The tolerances on dimensions for flat bars fulfill the European standard EN 10058. Our rolling mills have excellent capability to produce even tighter tolerances. The most common bar length is 6 meters, but can also range from 2.8 to 21 meters, depending on size and the producing rolling mill. Heat treatments may restrict the maximum length. Bars can be delivered sawn to exact lengths. Hot-rolled spring steel flat bars Ovako delivers hot-rolled spring steel flat bar according to European Standard EN-10092-1 (Profile A, B, C). The steel used in Ovako’s flat bars for spring manufacturing has very low levels of non-metallic inclusions and optimal hardenability. These contribute to a favorable yield to- tensile strength ratio in the quenched and tempered condition – a combination of properties that provides exactly the right qualities for the end product.
