R306
GB/T E5516-B2
AWS A5.5 E8016-B2
Sharaxaad: R306 waa bir bir ah oo kulaylka u adkaysata oo leh daahan potassium-hydrogen hooseeya oo ka kooban 1% Cr – 0.5% Mo. Labada AC iyo DC waa la isticmaali karaa, waxaana lagu alxan karaa dhammaan boosaska.Alxanka waa in horay loo sii kululeeyaa ilaa 160 ~ 250 ° C ka hor alxanka.
Codsiga: Waxaa loo isticmaalaa alxanka Cr 1% - Mo 0.5% birta kulaylka u adkaysata oo heerkulkiisu ka hooseeyo 520℃, sida tuubooyinka kulayliyaha, weelasha cadaadiska, uumiga iyo qalabka sifaynta batroolka, iwm.
Halabuurka kiimikada ee birta alxanka (%):
C | Mn | Si | Cr | Mo | S | P |
0.05 ~ 0.12 | 0.50 ~ 0.90 | ≤0.60 | 0.80 ~ 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 | ≥17 | ≥47 |
Hadda lagu taliyay:
Dhexroor usheeda (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
Alxanka Hadda (A) | 60 ~ 90 | 90 ~ 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.
