Molybdenum uye Chromium Molybdenum Heat Resistant Steel Welding Electrode

R306Fe                                                     

GB/T E5518-B2

AWS A5.5 E8018-B2

Tsanangudzo: R306Fe is pearlitic heat-resistant steel electrode ine iron powder uye yakaderera hydrogen potassium type coating ine 1% Cr - 0.5% Mo. Zvose AC uye DC zvinogona kushandiswa, uye zvinogona kusungirirwa munzvimbo dzose nepfupi arc operation.The preheating weldment uye tembiricha interlayer ari 160 ~ 250 °C panguva welding.

Chishandiso: Inoshandiswa kugadzira simbi ye1% Cr - 0.5% Mo pearlitic isingadziviriri kupisa (senge 15CrMo), senge bhailer kudziyisa pamusoro pepombi ine tembiricha yekushanda iri pasi pe550 ° C, mapaipi ehutsi uye midziyo yekumanikidza ine tembiricha yekushanda iri pasi pe520 ° C. , etc. Inogona kushandiswa kugadzira welding ye30CrMnSi steel castings.

Kemikari yakagadzirwa nesimbi weld (%):

Mechanical zvimiro zve weld simbi:

Diffusion hydrogen zvemukati mesimbi yakaiswa: ≤6.0mL/100g (glycerin nzira)

X-ray kuongorora: Ini giredhi

Yazvino inokurudzirwa:

Cherechedza:

1. Elekitirodhi inofanira kubikwa kweawa imwe panguva inenge 350 ℃ isati yaitwa welding;

2. Zvinokosha kuchenesa ngura, chikero chemafuta, mvura, uye tsvina pazvikamu zvewelding tisati tasveta.
