Kev piav qhia: G207NiMo yog ib lub hlau stainless hlau martensitic uas muaj txheej hydrogen sodium tsawg. Siv DCEP (direct current electrode positive) thiab tuaj yeem vuam tau txhua qhov chaw. Cov txheej surfacing muaj cov yam ntxwv zoo tiv thaiv cavitation thiab tiv thaiv xuab zeb hnav. Cov txheej txheem vuam surfacing yooj yim, tsis tas yuav tsum tau preheat ua ntej vuam, tsis tas yuav kho cua sov tom qab vuam, thiab cov txheej surfacing tuaj yeem ua machined.
Daim Ntawv Thov: Nws yog siv rau kev kho vuam ntawm 0Cr13Ni4Mo steel castings, kev kho qhov chaw ntawm cov dej ntws tom qab cavitation hnav, thiab vuam ntawm cov qauv ntawm cov khoom siv tib yam.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau vuam (%):
| C | Mn | Si | Cr | Ni | Mo | S | P |
| ≤0.06 | ≤1.0 | ≤0.90 | 11.0 ~ 12.5 | 4.0 ~ 5.0 | 0.40 ~ 0.70 | ≤0.03 | ≤0.04 |
Cov khoom siv kho tshuab ntawm cov hlau vuam:
| Khoom sim | Lub zog tensile Mpa | Kev ntev % |
| Tau lees paub | ≥760 | ≥15 |
Pom zoo tam sim no:
| Txoj kab uas hla ntawm tus pas nrig (hli) | 3.2 | 4.0 | 5.0 |
| Vuam Tam Sim No (Ib) | 80 ~ 120 | 120 ~ 160 | 150 ~ 190 |
Daim Ntawv Ceeb Toom:
1. Lub electrode yuav tsum tau ci rau 1 teev ntawm ib ncig ntawm 300 ℃ ua ntej welding ua haujlwm;
2. Nws yog ib qho tseem ceeb uas yuav tsum tau ntxuav cov xeb, cov roj, dej, thiab cov khoom tsis huv ntawm cov khoom vuam ua ntej vuam.
Wenzhou Tianyu Electronic Co., Ltd. tau tsim muaj xyoo 2000. Peb tau koom nrog kev tsim khoom ntawmvuam electrodes, cov pas nrig vuam, thiab cov khoom siv vuam rau 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.
