GR3 Qib SSAW Steel Yeeb Nkab
Siab zog · Superior Toughness
Multi-Txoj kev xaiv: 3PE / 3PP / FBE / TPEP
Tsim los rau nruab nrab - mus rau - siab siab, loj - txoj kab uas hla, thiab ib puag ncig nyuaj, pebGR3 qib Kauv Submerged -Arc Welded (SSAW) steel kavtau ua ke nrog kev lag luam- ua 3- txheej txheej tiv thaiv corrosion, xa cov kav dej txhim khu kev qha thiab ruaj khov rau cov roj & roj, dej, tshuaj lom neeg, thiab cov haujlwm ua haujlwm.
Vim li cas thiaj xaiv GR3 Qib?
| Khoom | GR1 / GR2 | GR 3 |
|---|---|---|
| Min. Yield zog | qis | Siab dua (feem ntau ntau dua lossis sib npaug rau 325 MPa, ib tus qauv) |
| Tensile zog | Ib txwm | Txhim kho rau siab - kev pabcuam siab |
| Tsawg-Tsub Impact Toughness | Nruab nrab | Kev txhim kho tseem ceeb rau thaj chaw txias |
| Daim ntawv thov | Tsawg-siab, kev pabcuam dav dav | Nruab nrab / siab siab, dej / hla, permafrost |
* Cov txiaj ntsig raug xa mus rau API 5L / ASTM / GB / T specifications.*
