Tshuaj Muaj Tshuaj
Tshuaj lom neeg muaj pes tsawg leeg ntawm STKR400 thiab STKR490 yog nruj me ntsis kev tswj hwm kom ntseeg tau cov khoom siv zoo ib yam:
| Lub ntsiab | Stkr400 (%) | Stkr490 (%) |
|---|---|---|
| Carbon (c) | Tsawg dua los yog sib npaug rau 0. 25 | Tsawg dua los yog sib npaug rau 0. 18 |
| Silicon (si) | - | Tsawg dua los yog sib npaug rau 0. 55 |
| Manganese (mn) | - | Tsawg dua los yog sib npaug rau 1.65 |
| Phosphorus (p) | Tsawg dua los yog sib npaug rau 0. 040 | Tsawg dua li lossis sib npaug rau 0. 035 |
| Sulphur (s) | Tsawg dua los yog sib npaug rau 0. 040 | Tsawg dua li lossis sib npaug rau 0. 035 |
Cov lus no ua kom cov Stkr400 thiab STKR490 muaj cov khoom xav tau thiab corrosion tsis kam.

Cov Khoom Siv Neeg Kho Tshuab
Cov cuab yeej ua haujlwm ntawm Stkr400 thiab STKR490 yog raws li hauv qab no:
| Ntiag tug | Stkr400 | Stkr490 |
|---|---|---|
| Tensile lub zog (mpa) | Ntau dua los yog sib npaug rau 400 | Ntau dua los yog sib npaug rau 490 |
| Yield zog (mpa) | Ntau dua los yog sib npaug rau 245 | Ntau dua los yog sib npaug rau 325 |
| Elongation (%) | Ntau dua los yog sib npaug rau 23 | Ntau dua los yog sib npaug rau 23 |
Cov khoom no ua rau STKR400 tsim nyog rau cov kev thov tsim qauv zoo, thaum STKR490 yog qhov zoo tagnrho rau cov ntawv thov muaj zog.
