Hom 441 Stainless Steel yog ferritic stainless hlau uas muab lub zog kub kub zoo (ntau tshaj ntawm Hom 409 thiab 439 Stainless Steels) ntxiv rau qhov zoo corrosion kuj nyob rau hauv ntau qhov chaw tso pa roj (sib npaug rau Hom 439 thiab 18 Cr-Cb Stainless Steels). Ferritic steels tsis yog qhov muaj zog ntawm qhov kub siab, tab sis columbium ntxiv nrog rau cov tshuaj tsim nyog annealing markedly txhim kho lub sij hawm ntev creep rupture zog. Hom 441 yog dual stabilized nrog niobium thiab titanium los muab kev zoo weld ductility thiab tsis kam mus rau intergranular corrosion nyob rau hauv weld tshav kub cuam tshuam cheeb tsam.
