Tungsten (w)	3.0 – 4.5	Cooperates nrog molybdenum los txhim kho pitting corrosion kuj, tshwj xeeb yog hauv chloride ib puag ncig.
Hlau (FE)	Tsawg dua los yog sib npaug rau 3.0	Txhim kho cov txheej txheem ua tiav (piv txwv li, kev ua haujlwm kub); tswj tau kom tsis txhob muaj zog tiv thaiv corrosion.
Cobalt (CO)	Tsawg dua los yog sib npaug rau 2.0	Tsawg tsawg los tiv thaiv cov kev cuam tshuam tsis zoo ntawm corrosion tsis kam nyob rau hauv cov xov xwm tshwj xeeb (xws li sulfuric acid).
Carbon (c)	Tsawg dua los yog sib npaug rau 0.015	Kev tswj hwm nruj ntawm cov qib qis kom tsis txhob ua cov carbides (piv txwv li, crrac₆) uas ua rau chromium depetion thiab txo corrosion tsis kam.
Silicon (si)	Tsawg dua los yog sib npaug rau 0.08	Impurity lub caij; Tsawg tsawg los tiv thaiv oxidation txheej spallation thiab txo cov brittleness.
Manganese (mn)	Tsawg dua los yog sib npaug rau 0.5	AIDS hauv DEEAGIDation thaum lub sijhawm smelting; tswj kom tsis txhob txo cov corrosion tsis kam.
Phosphorus (p)	Tsawg dua los yog sib npaug rau 0.015	Kev tsim txom impurity; nruj me ntsis txwv kom tiv thaiv cov intergranular corrosion thiab brittleness.
Sulphur (s)	Tsawg dua los yog sib npaug rau 0.010	Kev tsim txom impurity; txo qis kom tsis txhob txo qis dua thiab corrosion tsis kam.
Vanadium (V)	Tsawg dua los yog sib npaug rau 0.10	Luas lub caij; Tswj kom tsis txhob ua cov kauj ruam tsim teeb meem uas cuam tshuam rau kev ua tau zoo corrosion.
