Termostahl S.r.l. is a specialized and highly qualified factory which develops its activity in the field of high and medium frequency induction hardening of steels.
The experience ripened in so many years of activity together with a constant development of technologies has led to excellent results both in quality and treatments reliability.
Experience and technology that we offer to your company in order to undertake a factive collaboration to improve the level of the product/service offered.

We have at disposal more than 20 plants in high and medium frequency from 7 to 800 Kw, some of them with automatic search of frequency; automatic equipments studied for small and medium parts, furnace for preheating and stress relieving; magnetoscopic equipments for linear defects test.
We are really specialized in the treatment of:

We are usually working with partners in the fields of railway, Royal Navy, off-shore and air force.


Both into the workshop and laboratory there are specialized 2ND Level qualifield in PND-PT-MT controls methods who are enabled to check the treatd pieces to ensure the perfect execution of work. Moreover all the control instruments are periodically checked ( in accordance with the ISO 9000 normatives), second written procedures and all the data are then recorded.


Usual induction hardening procedure provides methodical controls of hardness and magnetoscopics to verify the presence/absense of cracks and/or material defects of steels. Second customer's request we can also execute destructive controls in order to verify the real hardening profile of workpieces, the relative depth and hardness at core. The frequency of such controls can be fixed in accordance with the customer for issue certifications "AD HOC " and statistics for series.
