Cov ntsiab lus thiab lawv lub luag haujlwm:

C (Carbon)Tsawg dua lossis sib npaug li 0.030%
Cov ntsiab lus carbon tsawg pab tiv thaiv kev nkag siab (ib hom corrosion uas tshwm sim ntawm cov pob qij txha). Qhov no txhim kho cov khoom tiv thaiv rau intergranular corrosion.

Si (Silicon)Tsawg dua lossis sib npaug li 0.75%
Silicon txhim kho oxidation tsis kam thiab txhim kho lub zog ntawm qhov kub thiab txias. Nws kuj pab nyob rau hauv cov txheej txheem steel ntau lawm los ntawm kev tshem tawm cov pa oxygen los ntawm cov hlau molten.

Manganese (Mn)Tsawg dua lossis sib npaug li 2.00%
Manganese pab txhawb rau cov khoom toughness thiab lub zog. Nws kuj tseem txhim khu kev tiv thaiv hnav thiab pab hauv cov hlau deoxidation thaum tsim khoom.

P (phosphorus)Tsawg dua lossis sib npaug li 0.045%
Phosphorus ua kom lub zog thiab ua haujlwm tau zoo tab sis khaws cia qis vim tias cov phosphorus ntau dhau tuaj yeem txo cov ductility thiab nce brittleness.

S (Sulfur)Tsawg dua lossis sib npaug li 0.015%
Sulfur txhim kho machinability tab sis ua tib zoo tswj vim tias qib siab dua tuaj yeem txo qhov toughness thiab corrosion kuj.

Cr (Chromium) 16.00–18.00%
Chromium yog lub hauv paus tseem ceeb hauv stainless hlau uas tsim cov txheej txheem chromium oxide passive, muab kev tiv thaiv corrosion thiab oxidation zoo heev.

Ni (Nickel) 10.00–14.00%
Nickel txhim kho corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv acidic ib puag ncig, thiab txhim kho cov khoom toughness, ductility, thiab tag nrho lub zog.

Molybdenum (zeeg) 2.00–3.00%
Molybdenum muab kev txhim kho corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nrog chlorides lossis lwm yam mob hnyav. Nws yog qhov txawv ntawm cov qib zoo li 316 stainless hlau, ua rau nws tiv taus pitting thiab crevice corrosion dua li 304 stainless hlau.
