Yeebsab |
Cr |
16.00 - 18.00 |
Cov ntsiab lus rau corrosion tsis kam; Cov ntaub ntawv ntom criao₃ passive zaj duab xis los tiv thaiv oxidation |
|
Tus menyuam yaus |
Ni |
10.00 - 14.00 |
Stabilizes austenite qauv; txhim kho qis - kub thiab kub ua thiab tiv thaiv kom txo cov kua qaub |
|
Molybdenum |
Mo |
2.00 - 3.00 |
Cov ntsiab lus sib txawv los ntawm AISI304; Tseem txhim kho kom tsis kam rau pitting / colice corrosion (piv txwv li, hauv qab ntsev, acidic ib puag ncig) |
|
Pa roj carbon |
C |
Tsawg dua los yog sib npaug rau 0.08 |
Tswj kom tsis txhob muaj intergranular corrosion; qis dua c cov ntsiab lus txo cov chromium carbide nag lossis nag lossis daus thaum tshav kub |
|

Tsawg dua los yog sib npaug rau 2.00 |
Txhim kho kom muaj lub sijhawm kub; Pab txheem hauv stabilizing Austenite (hloov ib nrab npib tsib xee) |
|
Phosphorus |
P |
Tsawg dua los yog sib npaug rau 0.045 |
Nruj me nyuam muaj kev cuam tshuam; Ntau cov ntsiab lus ua rau txias brittleness thiab txo corrosion tsis kam |
|
Leej mos |
S |
Tsawg dua los yog sib npaug rau 0.030 |
Txo impurity; siab s cov ntsiab lus tsis cuam tshuam weldability thiab nce kev ua phem rau kev xeb |
|
Nitrogen |
N |
Tsawg dua los yog sib npaug rau 0.10 |
Ib qho kev ua kom muaj txiaj ntsig; me ntsis txhim kho tensile lub zog uas tsis muaj kev cuam tshuam nyuaj |
