Corten B (ib EN 10025-5) muaj cov hauv qab notshuaj muaj pes tsawg leeg(los ntawm qhov hnyav feem pua), nthuav tawm hauv lub rooj kab rov tav kom pom tseeb:
| Element | Cov pa roj carbon (C) | Manganese (Mn) | Silicon (Si) | Phosphorus (P) | Sulfur (S) | Chromium (Cr) | Copper (Cu) | Nickel (Ni) | Vanadium (V) | Titanium (Ti) | Niobium (Nb) | Nitrogen (N) |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Cov ntsiab lus ntau | Tsawg dua lossis sib npaug li 0.12% | Tsawg dua lossis sib npaug li 1.00% | Tsawg dua lossis sib npaug li 0.50% | Tsawg dua lossis sib npaug li 0.035% | Tsawg dua lossis sib npaug li 0.035% | 0.40–0.80% | 0.25–0.55% | Tsawg dua lossis sib npaug li 0.65% | Tsawg dua lossis sib npaug li 0.12% | Tsawg dua lossis sib npaug li 0.15% | Tsawg dua lossis sib npaug li 0.06% | Tsawg dua lossis sib npaug li 0.012% |
Corrosion -Resistant Elements: Chromium (0.40–0.80%) thiab tooj liab (0.25–0.55%) yog cov tub ntxhais- lawv hnov mob nrog oxygen los ua cov tuab, tiv thaiv patina uas txhais cov huab cua steels.
Cov ntsiab lus carbon tsawg: Tsawg dua los yog sib npaug rau 0.12% carbon ua kom zoo weldability thiab tsis txhob nkig zones nyob rau hauv tshav kub - cuam tshuam cheeb tsam thaum fabrication.
Tswj Cov Khoom Muaj Teeb Meem: Kev txwv nruj ntawm phosphorus (tsawg dua lossis sib npaug li 0.035%) thiab sulfur (tsawg dua lossis sib npaug li 0.035%) tiv thaiv nkig inclusions thiab corrosion pib cov ntsiab lus.
Cov ntsiab lus pab: Nickel, vanadium, titanium, thiab niobium txhim khu lub zog thiab toughness yam tsis muaj kev cuam tshuam rau huab cua kev ua haujlwm.
