Our laboratory is an expert in the metallurgy and analysis of alloys, particularly stainless steel, and offers its expertise in analysing the chemical composition and controlling the grades of metal alloys.
Your needs: to carry out an analysis of the stainless steel alloy
Stainless steel is an iron alloy to which chromium (usually at least 10.5%) is added to give it excellent resistance to corrosion and oxidation. Other elements, such as nickel, molybdenum or carbon, may be added to improve its mechanical properties, heat resistance and durability. The special feature of stainless steel is the passivation layer formed by chromium, which creates a protective barrier on the surface against corrosive agents.
There are several types of stainless steel, classified according to their chemical composition and mechanical properties.
The different types of stainless steel and alloys
Stainless steel is a corrosion-resistant alloy thanks to its chromium content. Here are the main types:
Each type of stainless steel is chosen according to specific requirements for strength and durability.
Austenitic stainless steel
Martensitic stainless steel
Ferritic stainless steel
Duplex stainless steel
Analysis of stainless steel composition: essential quality control
By analysing the chemical composition of stainless steel, it is possible to verify the presence and concentration of essential alloying elements such as chromium, nickel and molybdenum, thus ensuring the conformity of materials for safety- and performance-critical applications.

FAQ
The analysis of rust spots on stainless steel makes it possible to determine the causes of corrosion and identify the elements that may have altered the protective chromium oxide layer. Techniques such as scanning electron microscopy (SEM), X-ray fluorescence spectrometry (XRF) and analysis of the chemical composition of deposits are used to assess the nature of surface contaminants or defects. This analysis helps to prevent future corrosion and improve the durability of stainless steel equipment.
Stainless steel is an alloy composed mainly of iron and at least 10.5% chromium, which gives it its resistance to corrosion by forming a protective layer of chromium oxide.
It often contains other elements, such as nickel to enhance stability, molybdenum for greater resistance to aggressive environments, and small amounts of carbon to improve hardness.
