1. Qhov sib txawv ntawm cov khoom siv neeg kho tshuab
| Cov khoom | A36 Welded Yeeb Nkab | A283GRC Welded Yeeb Nkab |
|---|---|---|
| Paib lub zog | Ntau dua los yog sib npaug ntawm 250 mpa (tuab tsawg dua lossis sib npaug nrog 50 hli) | 205 MPa |
| Lub zog tensile | 400 ~ 550 MPa | 380 ~ 515 MPa |
| Tsawg tus kub cuam tshuam lub zog | -29 Qib cuam tshuam lub zog loj dua los yog sib npaug rau 27J (tuab tsawg dua lossis sib npaug nrog 50 hli) | Tsis muaj kev ua haujlwm yuav tsum tau ua |
| Elongation | Ntau dua los yog sib npaug rau 20% 1 | Ntau dua los yog sib npaug rau 22% |
2. Sib Piv Ntawm Cov Tshuaj Muaj Zog
| Ntsiab lus | A36 Welded Yeeb Nkab | A283GRC Welded Yeeb Nkab |
|---|---|---|
| C | Tsawg dua los yog sib npaug rau 0.29% | Tsawg dua los yog sib npaug rau 0.24% |
| Mn | 0.8~1.2% | Tsawg dua los yog sib npaug rau 0.90% |
| P | Tsawg dua los yog sib npaug rau 0.04% | Tsawg dua los yog sib npaug rau 0.035% |
| S | Tsawg dua los yog sib npaug rau 0.05% | Tsawg dua los yog sib npaug rau 0.040% |
Qhov sib txawv tseem ceeb:
A36 txhim kho kom muaj zog los ntawm cov ntsiab lus manganese siab, thaum A283Grc tsom rau kev tswj cov phosphorus thiab leej faj los tswj kev tswjfwm;
A36 muaj cov pa roj carbon ntau dua (CeQ =0.35} ~ 0.47%), thiab kev pheej hmoo ntawm kev tawg txias thaum yuav tsum tau tiv thaiv.
3. Kev thov cov xwm txheej thiab cov yam ntxwv
| Ntaus | Cov Ntawv Thov | Kev txwv thiab cov txiaj ntsig zoo |
|---|---|---|
| A36 Welded Yeeb Nkab | Dynamically loaded qauv (txuas hniav, kev tsim cov thav duab, cov khoom siv.) | Siab Weldability / Luam Ntawv Tus nqi siab dua |
| A283GRC Welded Yeeb Nkab | Cov Khoom Siv Siab Zoo Li Qub (Cov Tso Tsheb Hlau Ceev, Cov Txheej Txheem Kev Lag Luam Dav) | Nruj nto moo zoo Tsis haum rau cov kev thauj khoom hnyav |
4. Cov Qauv thiab Tsim Kev Tsim Khoom
Cov Qauv Siv:
A36: Ua raws li Astm A36 / A36M (xaim hluav taws xob cov yeeb nkab);
A283GrC: Ua raws li ASTM A283 / A283M (tsom rau cov khoom siv zoo li qub).
Tus me nyuam xwm txheej:
Ob qho tib si tau xa hauv lub xeev kub-yob, thiab A283GrC tuaj yeem ntxiv rau kev kho ib txwm;
A36 welded kav yuav tsum muaj weld qhov kev pom kom pom, thiab A283GrC tsom rau saum npoo tsis muaj kev tswj hwm
