A complete range
We offer a complete range of solutions with 5 categories of Stainless Steel differentiated by the alloying elements added to iron, carbon and chromium.
0.015 to 0.10% carbon, 16 to 21% chromium, 6 to 26% nickel, 0 to 7% molybdenum. The presence of nickel improves corrosion resistance and makes stainless steel more ductile. The presence of molybdenum further enhances the resistance to corrosion in an acid medium. The most common grades are 304/304L et 316/316L.
0.02 to 0.06% carbon, 10.5 to 30% chromium, 0 to 4% molybdenum. These grades commonly used internally are now being developed for envelope and structural products.
0.02% carbon, 0 to 4% molybdenum, 1 to 7% nickel and 21 to 26% chromium. They offer excellent qualities for a cost price that is contained because of their low nickel content, material that suffers from highly speculative prices.
0.1% carbon, 10.5 to 17% chromium. Mainly used for tooling, cutting tools and springs.
these are chromium manganese steels, with a low nickel content (always below 5%).
The stainless steels that are traditionally used for Building & Construction can be grouped into three major categories:
Each of these families has specific mechanical properties:
hardness, yield stress, breaking strength, elongation, etc. For example, austenitic and austenoferritic stainless steels have expansion coefficients higher than the other steels. Their thermal conductivity is less than ferritic stainless steel and traditional steels. The austenitics have a very high level of resilience – the ability of a material to resist brittle fracture – at any temperature. Due to their very high yield strengths, superior to other steels and better than other stainless steels families, Duplex are commonly used for structures, bridges and footbridges.
