✅ Isebenza ngqo efeni – Intengo yokuncintisana nokulethwa okusheshayo
Ukukhethwa Kwebanga – Isevisi Yezinga Lokushisa Eliphansi
| Ibanga | Izinga Lokushisa Lokusebenza | Izinga Lokushisa Lokuhlolwa Komthelela | Uhlobo Lwezinto | Amandla Okuqina (MPa) | Ukukhishwa (MPa) |
|---|---|---|---|---|---|
| I-Grade 1 | -45°C (-50°F) | -45°C | Insimbi yekhabhoni | ≥380 | ≥205 |
| I-Grade 6 | -45°C (-50°F) | -45°C | Insimbi yekhabhoni | ≥415 | ≥240 |
💡 Ibanga 6 liyathandwa ezicelweni eziningi – inikeza amandla aphezulu (≥415 MPa tensile) uma iqhathaniswa ne-Grade 1 (≥380 MPa) ezingeni lokushisa elifanayo lokusebenza.
Ukwakheka Kwamakhemikhali
| Ibanga | C max | Mn | P max | S max | Si |
|---|---|---|---|---|---|
| I-Grade 1 | 0.30 | 0.40-1.06 | 0.025 | 0.025 | — |
| Ibanga 6 | 0.30 | 0.29-1.06 | 0.025 | 0.025 | ≥0.10 |
📌 Qaphela ngebanga 1: Ukwehla ngakunye kwe-carbon engu-0.01% ngaphansi kuka-0.30% kuvumela ukwenyuka kwe-manganese engu-0.05% ngaphezu kuka-1.06%, kufinyelele kumkhawulo ongu-1.35%.
Izici Zomshini
| Ibanga | Amandla Okudonsa (MPa) | Amandla Okuvumela (MPa) | Ukunwebeka (%) |
|---|---|---|---|
| I-Grade 1 | ≥380 | ≥205 | ≥35 |
| Ibanga 6 | ≥415 | ≥240 | ≥30 |
Izidingo Zokushaywa Kwe-Charpy Ezingeni Lokushisa Eliphansi
| Ibanga | Izinga Lokushisa Lokuhlola (°C) | Amandla Amaphakathi (J) | Okuncane Ngamunye (J) |
|---|---|---|---|
| I-Grade 1 | -45 | 18 | 14 |
| Ibanga 6 | -45 | 18 | 14 |
💡 Ukuhlolwa kwe-Charpy impact kuyimpoqo kukho kokubili Ibanga 1 kanye neBanga 6 ku--45°C – umbiko oqinisekisiwe unikezwa ngayo yonke ukuthunyelwa.
Inqubo Yokukhiqiza – Ukudonsa Okubandayo Nokuqina Ezingeni Lokushisa Eliphansi
Inqubo Yokudonsa Ebandayo Yesevisi Yezinga Lokushisa Eliphansi:
-
Amashubhu agingqiwe ashisayo ziyahlanzwa ukuze kususwe isikali
-
Ukudonsa okubandayo inciphisa ngokunembile ububanzi
-
Ukwelashwa ngokushisa (ukujwayisa noma ukukhulula ingcindezi) – iqinisekisa ukwakheka kwezinhlayiya ezinhle ukuze kutholakale ukuqina ekushiseni okuphansi
-
Ukuqondisa – iqinisekisa ukungaguquguquki kobukhulu
-
Ukusika okunembile – ubude obunembile
-
Ukuhlolwa kwe-NDT nokuhlolwa kwe-hydrostatic okungu-100% – liqinisekisa ubuqotho
-
Ukuhlolwa kwe-Charpy impact ku-45°C – iqinisekisa ukuqina ekushiseni okuncane
Ukuqhathanisa Amabanga – Ibanga 1 vs Ibanga 6
| Isici | I-Grade 1 | I-Grade 6 |
|---|---|---|
| Amandla Okudonsa | ≥380 MPa | ≥415 MPa (phezulu) |
| Amandla Okuvumela | ≥205 MPa | ≥240 MPa (phezulu) |
| Ukutholakala Kwe-Manganese | 0.40-1.06% | 0.29-1.06% |
| Ukutholakala Kwe-Silicon | Akucaciswanga | ≥0.10% |
| Ukusetshenziswa Okujwayelekile | Ukushisa okuncane okujwayelekile | Lidume kakhulu – amandla aphezulu |
💡 Ibanga 6 linikeza amandla okudonsa aphakeme ngama-17% kune-Grade 1 – ekhethwayo ezimweni eziningi zokushisa okuphansi lapho amandla aphezulu ewusizo.
Izicelo Eziyinhloko – Isevisi Yokushisa Ephansi
