| Sulfur (S) | Tsawg dua lossis sib npaug li 0.010% | Tsawg dua lossis sib npaug li 0.015% | P355GH muajstricter sulfur tswjkom huv si zoo dua thiab siab -kev ua haujlwm kub. |
| Molybdenum (Mo) / Lwm yam Alloys | Tej zaum yuav muaj kab mob Mo, Nb, V rau ntxiv dag zog | Feem ntau cov pa roj carbon monoxide -manganese raws li | P355GH tuaj yeem sivmicroalloying cov ntsiab luskom ua tiav lub zog siab dua yam tsis muaj kev cuam tshuam toughness. |
Mechanical Properties
| Khoom | P355GH (EN 10028-2) | P265GH (EN 10028-2) | Qhov txawv tseem ceeb |
|---|---|---|---|
| Yield zog (ReH) | Ntau dua lossis sib npaug li 355 MPa (rau thickness Tsawg dua lossis sib npaug li 16 hli) | Ntau dua lossis sib npaug li 265 MPa (rau thickness Tsawg dua lossis sib npaug li 16 hli) | P355GH muaj zog ntau dua tawm los, ua rau nws haum rau siab dua - cov ntawv thov siab. |
| Tensile zog (Rm) | 490-630 MPa | 410-530 MPa | P355GH muaj ib tugsiab zog tensile ntau yamkom tiv taus kev kub ntxhov ntau dua. |
| Elongation (A5) | Ntau dua lossis sib npaug li 20% (rau thickness Tsawg dua lossis sib npaug li 16 hli) | Ntau dua lossis sib npaug li 22% (rau thickness Tsawg dua lossis sib npaug li 16 hli) | P265GH muaj qhov elongation zoo dua me ntsis, tab sis ob qho tib si muab cov ductility txaus rau cov hlab ntsha siab. |
| Impact Toughness | Ntau tshaj lossis sib npaug rau 27 J ntawm 0℃lossis raws li tau teev tseg | Ntau tshaj lossis sib npaug rau 27 J ntawm 0℃lossis raws li tau teev tseg | Ob leeg xav tau kev ua tau zoo, tab sis P355GH lub zog siab dua yuav xav tauceev faj dua kev kho cua sovtswj nws. |
