Spring steels
The main properties of a spring steel are those of bearing an intermittent load, accumulating energy and measuring forces.
It must have an elastic deformation without plastic alteration, so the yielding unit load shall be elevated and this is achieved after an adequate quenching and tempering.
Spring steels must have an elevated hardenability, verified with the Jominy hardenability that allows to calculate martensite at heart that you can obtain, which has to be at least 80%.
In order to get a better elasticity and a high elastic limit, spring steels must have a fine grain to be less sensible to overheating.
They must have an elevated tensile strength and fatigue strength, combined with plastic reserve, consequently toughness is diminished.
Inclusions and superficial defects have to remain within restricted limits. Steels with SI, CR and NI have an elevated elastic limit and a great hardenability. They are employed for springs and twist bars.
Steels
Our steel always comes from the same European steelworks, which guarantee a continuity for what concerns quality. The constant quality of the supplies allows to have repetitive parameters in mechanical processing and a greater control over deformations during heat treatment.
Machining
Precise cuttings of small and big series are guaranteed by the employement of latest generation automatic saws that were projected and realized in order to guarantee precision standards required by customers, reducing processing wastage.
Quality
The certification and introduction of the Quality System management allowed M.T.Acciai to improve not only its efficiency, but also the quality that is offered, in order to better meet our customers’ needs.
