Steel is an alloy of iron and carbon. Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements.
Aperam offers a complete range of solutions. Our five categories of Stainless Steels are differentiated by the alloying elements added to iron, carbon and chromium.

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 and 316/316L.

0.02 to 0.06% carbon, 10.5 to 30% chromium, 0 to 4% molybdenum. Commonly used internally, these grades are now being developed for envelope and structural products.
KARA is the Aperam brand for ferritic stainless steels. Unlike other stainless steels, the KARA range doesn’t contain nickel and is thus immune from the erratic price fluctuations of this alloying element. As a result, prices are more stable over time, giving KARA a strong argument in the construction sector where project cost and economic design are key elements.

0.02% carbon, 0 to 4% molybdenum, 1 to 7% nickel and 21 to 26% chromium. These stainless steels not only offer excellent quality, because of their low nickel content – a material that suffers from highly speculative prices – they are also very cost effective.

General Properties of Stainless Steel365体育APP下载|首页
Resistance to fire365体育APP下载|首页
Stainless steel fully meets requirements in fields such as decoration and cooking utensils that require frequent and effective washing.
These qualities make stainless steel ideally suited to building applications exposed to adverse weather, such as roofs, facades, rainwater recovery systems and domestic water pipes. Stainless steel’s longevity fulfils the requirements of sustainable construction, and effective election, installation and low maintenance guarantee the user unrivalled service life.
- resistance to oxidation and creep resistance at high temperatures
- strength and ductility at low temperatures
- good mechanical properties
- easy to work with (stamping, bending, hydroforming, welding, brazing…)
