Kev piav qhia: A207 yog cov hlau tsis xeb Cr18Ni12Mo2 uas muaj cov pa roj carbon tsawg nrog cov txheej sodium hydrogen tsawg. Siv DCEP (cov hlau tam sim no ncaj qha zoo) thiab tuaj yeem vuam rau txhua qhov chaw. Txij li thaum cov hlau tso muaj molybdenum, nws muaj kev tiv thaiv corrosion zoo, tiv thaiv kub thiab tawg, tshwj xeeb tshaj yog zoo rau kev tiv thaiv chloride ion pitting corrosion.
Daim Ntawv Thov: Siv rau kev vuam cov qauv hlau tsis muaj carbon 06Cr17Ni12Mo2, nrog rau cov hlau chromium siab (xws li Cr13, Cr17, thiab lwm yam) uas tsis tas yuav kho cua sov tom qab vuam, thiab vuam cov hlau sib txawv.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Si | Cr | Ni | Mo | Cu | S | P |
| ≤0.08 | 0.5 ~ 2.5 | ≤0.90 | 17.0 ~ 20.0 | 11.0 ~ 14.0 | 2.0 ~ 3.0 | ≤0.75 | ≤0.030 | ≤0.040 |
Cov khoom siv kho tshuab ntawm cov hlau vuam:
| Khoom sim | Lub zog tensile Mpa | Kev ntev % |
| Tau lees paub | ≥520 | ≥30 |
Pom zoo tam sim no:
| Txoj kab uas hla ntawm tus pas nrig (hli) | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| Vuam Tam Sim No (Ib) | 25 ~ 50 | 50 ~ 80 | 80 ~ 110 | 110 ~ 160 | 160 ~ 200 |
Daim Ntawv Ceeb Toom:
- Lub electrode yuav tsum tau ci rau 1 teev ntawm kwv yees li 250 ℃ ua ntej vuam ua haujlwm. Tsis txhob ci ntau zaus.
Wenzhou Tianyu Electronic Co., Ltd. tau tsim muaj xyoo 2000. Peb tau koom nrog kev tsim khoom ntawmvuam electrodes, cov pas nrig vuam, thiabcov khoom siv vuamtau ntau tshaj 20 xyoo.
Peb cov khoom tseem ceeb suav nrog cov hlau tsis xebvuam electrodes, carbon steel welding electrodes, low alloy welding electrodes, surfacing welding electrodes, nickel & cobalt alloy welding electrodes, mild steel & low alloy welding wires, stainless steel welding wires, gas-shielded flux cored wires, aluminium welding wires, submerged arc welding. wires, nickel & cobalt alloy welding wires, tooj dag welding wires, TIG & MIG welding wires, tungsten electrodes, carbon gouging electrodes, thiab lwm yam khoom siv vuam & khoom siv tau.
