Your needs: chemical analysis of stainless steel and stainless steel alloys
Using state-of-the-art equipment and rigorous methods, our laboratory guarantees precise stainless steel test, in line with the challenges of materials control and stringent quality control.
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:
- Austenitic stainless steel : Used in the food, medical and marine industries, it offers excellent corrosion resistance.
- Ferritic stainless steel : Less expensive, magnetic and resistant, it is commonly used in the automotive and household appliance industries.
- Martensitic stainless steel : Strong and hard, ideal for tools and blades.
- Duplex stainless steel : Highly resistant, suitable for corrosive environments, used in the oil and chemical industries.
Each type of stainless steel is chosen according to specific needs for strength and durability.
Analysis of stainless steel alloys: comprehensive expertise
Stainless steel and its alloys, used in a wide range of sectors including aerospace, automotive and food processing, require specific compositions to guarantee their strength and durability. Our expertise covers all stainless steel alloys, to help our customers meet technical specifications and industrial standards.
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, ensuring the conformity of materials for safety- and performance-critical applications.
