Positive influence on the performance of your components.
Heat treatment is often necessary or advisable to achieve the required material properties. The performance of the components is decisively influenced by the targeted setting of the optimum parameters. For this purpose, S+C has a number of state-of-the-art facilities available. We improve the structures and properties of the material and thus, e.g. may optimally prepare tubes for a subsequent bending.
By the way: We would be happy to accept your order for subcontract heat treatment. Just take the opportunity and use our services now. Whether bars, discs, blocks or other product shapes, there are no limits to the geometries to be treated at S+C.
Solution annealing + quenching.
Solution annealing is a heat treatment process that is mainly used for austenitic steels and alloys, but also for duplex steels. In this process, the carbides that are precipitated in the microstructure, as well as other phases in the solid solution matrix, are dissolved and prevented from re-precipitating by abrupt cooling. Depending on the material requirements, water, polymer (oil substitute) or air quenching is selected for this purpose.
For annealing, the steel is held, at a constant temperature, for a certain time with slow cooling. This reduces lattice defects in the crystal structure, improving both elongation and formability. The reduced hardness allows a better machinability of the work pieces.
Martensitic steels are first hardened and then tempered to achieve the required hardness.
The aim of stress relieving is to reduce internal stresses in steel components without a significant modification of the microstructure and the material properties.
Cold and hot straightening.
At S+C, the straightening press is designed for a press force of up to 300 mt. It can be used for both, cold and hot straightening. In hot straightening, the products are placed directly from the furnace onto the press. Furnace and press are located in the same building.
Precipitation hardening / Aging.
At certain materials, a subsequent heat treatment is possible after solution annealing and quenching, in order to increase strength by precipitation of intermetallic phases.
For components with ideal material properties.
