A major part of the steel produced by Ovako is low-alloyed engineering steels. This group includes case hardening, quenched and tempered, spring, boron, through hardening and nitriding steels.
Micro alloyed steels for yield strength, impact and weldability
The micro alloyed steels are delivered rolled or normalizing rolled. Thanks to their cleanleness and fine grane size, these steels are easy to cold form or bend. This makes them especially suitable for use in the vehicle, hydraulic and general engeneering industries.
Spring steels for fatigue resistance and strengthSpring steels are mainly used for the manufacture of different kinds of springs for the automotive industry. These steels are usually alloyed with chromium or silicon with additons of vanadiumand molybdenum, where bigger sizes are required. Our development in reasent years has focused on improving fatigue resistance and strength in this group of steels.
Boron steels for hardenabilityFor agricultural machines such as ploughs, Ovako supplies different grades of boron steels. Boron steel are used also in other wear resistance parts for forestry and off-road vehicles, and also in fasteners. Boron alloying even in small quantities significantly increases the hardenability of the steel. Often more highly alloyed steel grades can be replaced with boron steel.
Through-hardening steels for endurance
Rolling bearing elements are expected to last longer and to endure more and more stress. To meet theese enquirements Ovako conducts consistant development, working side by side with the leading manufacturers of rolling bearings.
Ovako's bearing steels are also used in a number of other applications, where strength and wear resistances are important factors.
Nitriding steels for corrosion resistance and special properties
Ovako's nitriding steels are designed as a multipurpose steel grade with many favorable properties wich can be utilized in a variety of applications, e. g. in transmissions or hydraulic components, tools and other mechanical parts with severe demands on wear and corrosion resistance or mechanical properties.
M-steel - for improved machinability
The "M" in M-steel stands for Machinability. M-steels are based on treated non-alloyed or low-alloyed special steel. M-treatment means that all production processes are thoroughly controlled to achieve optimal cutting ability.
In manufacturing of various detailes, cutting processes are often a considerable cost factor. M-steel lowers these costs by allowing high cutting speeds and a non-interrupted production environment. With a cutting speed of up to 30 % over conventional steels, Ovako's M-steel meets market demands for lower processing costs.
