Austenitic stainless steels

Pink Carbon Carbon
Orange Chromium Chromium
Purple Nickel Nickel
Green Molybdenum Molybdenum

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.

Ferritic S400 Solutions KARA

Pink Carbon Carbon
Orange Chromium Chromium
Green Molybdenum Molybdenum

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.

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 elements.

Prices are more stable over time: a strong argument in the construction sector where projects costing and economic design are key elements.

Applications

Car exhaust systems, conveyor chains, cooking utensils, boilers domestic electrical appliances, domestic appliances, trim, dishware, heating, hot water tanks, tubes …
