Molybdenum iyo Chromium Molybdenum Kuleyl u adkaysta Birta alxanka Electrode
R306Fe
GB/T E5518-B2
AWS A5.5 E8018-B2
Sharaxaad: R306Fe waa koronto bir ah oo kulaylka u adkeysata leh oo leh budada birta iyo nooca potassium hydrogen hooseeyo oo ka kooban 1% Cr - 0.5% Mo. Labada AC iyo DC waa la isticmaali karaa, waxaana lagu alxan karaa dhammaan jagooyinka iyada oo hawl gaaban gaaban.Kuleylka hore ee alxanka iyo heerkulka interlayerku waa 160 ~ 250 °C inta lagu jiro alxanka.
Codsiga: Waxaa loo isticmaalaa alxanka 1% Cr - 0.5% Mo birta kulaylka u adkeysata (sida 15CrMo), sida kuleyliyaha tuubooyinka dusha sare ee heerkulka shaqada ee ka hooseeya 550C, tuubooyinka uumiga iyo weelasha cadaadiska leh heerkulka shaqada ee ka hooseeya 520 ° C , iwm. Waxa loo isticmaali karaa alxanka 30CrMnSi birta ah.
Halabuurka kiimikada ee birta alxanka (%):
| C | Mn | Si | Cr | Mo | S | P |
| 0.05 ~ 0.12 | 0.50 ~ 0.90 | ≤0.50 | 1.00 ~ 1.50 | 0.40 ~ 0.65 | ≤0.030 | ≤0.030 |
Qalabka makaanikada ee birta alxanka:
| Shayga tijaabi | Xoog xajin Mpa | Xoog soo saar Mpa | Dheeraynta % | Qiimaha saamaynta (J) Heerkulka caadiga ah |
| La damaanad qaaday | ≥540 | ≥440 | ≥47 | ≥27 |
| La tijaabiyay | 550 ~ 640 | ≥450 | 20 ~ 28 | 105 ~ 150 |
Mawduuca hydrogen firidhsan ee birta kaydsan: ≤6.0mL/100g (hab glycerin)
Kormeerka raajada: Waxaan darajo
Hadda lagu taliyay:
| Dhexroor usheeda (mm) | 3.2 | 4.0 | 5.0 |
| Alxanka Hadda (A) | 100 ~ 130 | 140 ~ 180 | 180 ~ 210 |
Ogaysiis:
1. Electrode waa in lagu dubaa 1 saac agagaarka 350 ℃ ka hor alxanka;
2. Waa lagama maarmaan in la nadiifiyo miridhku, miisaanka saliidda, biyaha, iyo wasakhda qaybaha alxanka ka hor.
