Quenched and tempered steels
Heat-treatable steels - The optimum solution for demanding applications
As a reliable and experienced partner for special steels and nickel-based alloys, Remystahl GmbH places the highest value on quality, safety and precision. In the field of heat-treatable steels, we offer materials that impress with their specific properties and performance.
With our consistently high quality standards, we support our customers in meeting even the most demanding requirements. Quenched and tempered steels are characterized by a combination of high strength and toughness. These properties are achieved through heat treatments such as hardening and annealing.
The targeted adaptation of these processes not only makes the steel more resistant, but also more flexible to mechanical stresses. Quenched and tempered steels are particularly indispensable in sectors such as mechanical engineering, the automotive industry and fasteners, as they guarantee high wear resistance and a long component service life.
