KARA is Aperam’s Brand of 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.
Well-known standard ferritic grades 409 (K09), 410 (K10) and 430 (K30) are used in such applications as washing-machine drums and exhaust systems. More recently-developed ferritic grades, such as 439 (K39) and 441 (K41), meet an even broader range of requirements. They can be formed to more complex shapes and joined using most conventional joining methods, including welding. Thanks to the addition of molybdenum, ferritic grade 444’s (K44) resistance to localised corrosion is at least equal to that offered by austenitic grade 316.
