Molybdenum uye Chromium Molybdenum Heat Resistant Steel Welding Electrode
R407
GB/T E6015-B3
AWS A5.5 E9015-B3
Tsanangudzo: R407 is pearlitic heat-resistant steel electrode ine yakaderera-hydrogen sodium coating ine 2.5% Cr - 1% Mo. Shandisa DCEP (yakananga ikozvino electrode yakanaka) uye inogona welded munzvimbo dzose.Iyo weldment inofanira kunge isati yatanga kupisa kusvika 200 ~ 300 ° C isati yave welding.
Chikumbiro: Inoshandiswa kukwenenzverwa kwepamusoro-tembiricha uye yakakwirira-kudzvanywa mapaipi ane tembiricha yekushanda iri pasi pe550 ° C, michina yemakemikari yekugadzira, petroleum yekupwanya michina, nezvimwe.
Kemikari yakagadzirwa nesimbi weld (%):
| C | Mn | Si | Cr | Mo | S | P |
| 0.05 ~ 0.12 | 0.50 ~ 0.90 | ≤0.50 | 2.00 ~ 2.50 | 0.90 ~ 1.20 | ≤0.030 | ≤0.030 |
Mechanical zvimiro zve weld simbi:
| Test chinhu | Kusimba simba Mpa | Goho simba Mpa | Elongation % | Impact value (J) Normal Temp. |
| Guaranteed | ≥590 | ≥490 | ≥15 | ≥47 |
| Tested | 600 ~ 680 | ≥500 | 18 ~ 21 |
Diffusion hydrogen zvemukati mesimbi yakaiswa: ≤4.0mL/100g (glycerin nzira)
X-ray kuongorora: Ini giredhi
Yazvino inokurudzirwa:
| Tsvimbo dhayamita (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
| Welding Current (A) | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Cherechedza:
1. Iyo electrode inofanira kubikwa kweawa imwe pa 350 ℃ isati yaitwa welding;
2. Zvinokosha kuchenesa ngura, chikero chemafuta, mvura, uye tsvina pazvikamu zvewelding tisati tasveta.
