Definition of Stainless Steels
The Stainless Steels are alloys iron, chrome and carbon based, enriched with other elements such as nickel, molybdenum, silicon, titanium and more.
Their main characteristic is the high resi stance to the corrosion of the atmosphere.
This characteristic is due to the spontaneous formation of a thin layer of chrome oxides (Pict.1) that protects the metal against the corrosive attacks.

Seizure phenomenon when mounting stainless steel fasteners
When mounting stainless steel nuts on screws or threaded parts it’s likely to run into the seizure phenomenon of the nut on the male thread.
The attachment describes the phenomenon and clarify the aspects affecting it.
Passivation of stainless steels
Pickling and Passivation becomes of primary importance when we talk about an Inox Component. In fact they put this material in the best possible conditions for promoting the passivation mechanism, this last being at the very base of the stainless behavior.
Professionalism means recognizing the need of a customer and knowing how to fulfill it. For Fiminox, guaranteed quality compare to deadlines and great reliability in commercializing INOX screws and bolts, are pillars of daily activity, as well as the main strength.
The high quality service offered comes from the experience gained in the field of stainless steel fasteners both in the unified market and in the production of special parts.
A high technological level is essential in order to guarantee certified products in compliance with the regulations in force. Since 2003 Fiminox has relied on a company quality system certified by DET NORSKE VERITAS (ACCREDIA accredited body) and recently updated according to ISO 9001: 2015 procedures; this guarantees our products according to the criteria of total quality with the control of technology and of the entire production process. The incoming controls are carried out with the most modern equipment that tests dimensional accuracy, functional and chemical correctness. The same attention is given to the checking out materials that are carried out through optical readers and bar codes and are based on a double level of verification.
