AWS A5.4 E309-15
Nqe lus piav qhia: A302 yog Cr23Ni13 stainless hlau electrode nrog qis hydrogen sodium txheej.Siv DCEP (cov khoom siv hluav taws xob ncaj qha tam sim no) thiab tuaj yeem txuas rau txhua txoj haujlwm.Cov hlau deposited muaj zoo tawg kuj thiab oxidation kuj.
Daim ntawv thov: Siv rau vuam tib yam stainless hlau, tshwj xeeb-zoo li tus hlau, siab chromium hlau, siab manganese hlau, thiab lwm yam.
Tshuaj muaj pes tsawg leeg ntawm weld hlau (%):
| C | Mn | Si | Cr | Ni | Mo | Cu | S | P |
| ≤ 0.15 | 0.5 ~ 2.5 hli | ≤0.90 | 22.0-25.0 Nws | 12.0 ~ 14.0 Nws | ≤ 0.75 | ≤ 0.75 | ≤ 0.030 | ≤ 0.040 |
Mechanical zog ntawm weld hlau:
| Cov khoom kuaj |
Tensile zog Mpa | Elongation % |
| lav | ≥550 | ≥ 25 |
Pom zoo tam sim no:
| Qws txoj kab uas hla (mm) | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| Vuam tam sim no (A) | 25 ~ 50 | 50 ~ 80 | 80 ~ 110 ib | 110 ~ 160 ib | 160-200 Nws |
Daim ntawv ceeb toom:
Cov electrode yuav tsum tau ci rau 1 teev ntawm ib ncig ntawm 150 ℃ ua ntej vuam ua haujlwm.
Wenzhou Tianyu Electronic Co., Ltd. tau tsim nyob rau xyoo 2000. Peb tau koom nrog kev tsim khoom ntawmvuam electrodes, vuam rods, thiabvuam consumablesrau ntau tshaj 20 xyoo.
Peb cov khoom tseem ceeb muaj xws li stainless hlau vuam electrodes, carbon steel vuam electrodes, tsis tshua muaj hlau vuam electrodes, surfacing vuam electrodes, npib tsib xee & cobalt alloy vuam electrodes, me steel & tsawg alloy vuam hlau, stainless hlau vuam hlau, roj-shielded flux cored nyob ntawm tej, aluminium welding hlau, submerged arc vuam.Cov xov hlau, npib tsib xee & cobalt alloy vuam hlau, tooj dag vuam hlau, TIG & MIG vuam hlau, tungsten electrodes, carbon gouging electrodes, thiab lwm yam vuam accessories & consumables.
