Kev vuam tawvHluav taws xob
Txheem: DIN 8555 (E1-UM-350)
Hom No.: TY-C DUR 350
Kev Qhia Txog & Daim Ntawv Thov:
· Cov electrode SMAW txheej txheem yooj yim rau kev tawg thiab hnav tsis kam.
· Tsis yooj yim puas. Yooj yim vuam rau txhua qhov chaw.
· Tshwj xeeb tshaj yog tsim rau cov nplaim uas tiv taus kev hnav ntawm Mn-Cr-V alloyed qhov chaw, xws li qav, khiav rollers, saw txhawb nqa yob, sprocket log, coj yob thiab lwm yam.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm cov hlau uas tau tso rau hauv (%):
|
| C | Si | Mn | Cr | Fe |
| DIN | - | - | - | - | - |
| EN | - | - | - | - | - |
| Ib txwm muaj | 0.20 | 1.2 | 1.40 | 1.8 | Bal. |
Hardness ntawm cov hlau tso rau hauv:
| Raws li Welded (HB) | 1 txheej ntawm cov hlau nrog C = 0.5% (HB) |
| 370 | 420 |
Cov Yam Ntxwv Dav Dav:
· Microstructure Ferrite + Martensitic
· Kev Siv Tau Zoo nrog Tungsten carbides tipped cov cuab yeej
· Ua ntej cua sov Ua ntej cua sov cov khoom hnyav thiab cov hlau tensile siab dua rau 250-350 ℃
· Rov ziab dua rau 2 teev ntawm 300 ℃ ua ntej siv.
