Composition of Stainless Steel
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. Stainless steel’s corrosion resistance and mechanical properties can be further enhanced by adding other elements, such as nickel, molybdenum, titanium, niobium, manganese, etc.
Reaction to Contact with Air, Humidity or Water
On contact with oxygen, a chromium oxide layer is formed on the surface of the material. This passive layer protects it and has the unique ability to repair itself.

Stainless Steel Families
Austenitics with manganese or 200 series
These are chromium manganese steels, with a low nickel content (always below 5%).
Applications
Asphalt tankers, tubes, food containers, silos, conveyor chains, safety soles, etc.
Austeno-ferritics or Duplex
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.
Applications
Oil, gas, pulp and paper, desalination sectors, chemical industry, etc.
Martensitics
0.1% carbon, 10.5 to 17% chromium.
Applications
Cutlery, cutting tools, hand tools, springs, etc.
Austenitics or 300 series
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 in certain media 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.
Applications
Boiler market, aeronautics, electronic components, railway equipment, tubes, chemical tanks and food vats, marine applications, containers, etc.
Heat resistant steel applications
Heating systems, resistor jackets, furnace equipment.
Ferritics or 400 series: the KARA ferritic offer
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.
Applications
Car exhaust systems, conveyor chains, cooking utensils, boilers, domestic appliances, trim, dishware, heating, hot water tanks, tubes, etc.
