Molybdenum a me Chromium Molybdenum Kūpaʻa i ka WelaKuʻi kilaʻElekoda
R406
GB/T E6016-B3
ʻAWS A5.5 E9016-B3
Wehewehe: He electrode kila pearlitic kūpaʻa wela ʻo R406 me kahi uhi potassium haʻahaʻa-hauwai e loaʻa ana he 2.5% Cr - 1% Mo. Hiki ke hoʻohana ʻia ʻo AC a me DC, a hiki ke hoʻopaʻa ʻia ma nā kūlana āpau. Pono e hoʻomehana mua ʻia ka hoʻopaʻa ʻana i 160 ~ 200°C ma mua o ka hoʻopaʻa ʻana.
Noi: Hoʻohana ʻia no ka hoʻoheheʻe ʻana i nā hale kila pearlitic Cr2.5Mo kūpaʻa wela, e like me nā paipu wela kiʻekiʻe a me ke kaomi kiʻekiʻe me nā mahana hana ma lalo o 550 ° C, nā mīkini kemika synthetic, a me nā lako hana haki petroleum.
Ka hoʻohuihui kemika o ka metala i hoʻoheheʻe ʻia (%):
| 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 |
Nā ʻano mechanical o ka metala i hoʻoheheʻe ʻia:
| Mea hoʻāʻo | Ikaika tensile Mpa | Ikaika hāʻawi Mpa | Hoʻolōʻihi % | Ka waiwai hopena (J) Mahana Maʻamau. |
| Hōʻoiaʻiʻo ʻia | ≥590 | ≥490 | ≥15 | ≥47 |
Ka nui o ka hydrogen diffusion o ka metala i waiho ʻia: ≤4.0mL/100g (ʻano glycerin)
Nānā X-ray: papa I
Manaʻo ʻia kēia manawa:
| Anawaena o ke koʻokoʻo （mm） | 2.5 | 3.2 | 4.0 | 5.0 |
| KuʻihaoI kēia manawa （A） | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Hoʻolaha:
1. Pono e hoʻomoʻa ʻia ka electrode no 1 hola ma kahi o 350 ℃ ma mua o ka hana kuʻihao;
2. He mea nui e hoʻomaʻemaʻe i ka ʻōpala, ka unahi aila, ka wai, a me nā mea haumia ma nā ʻāpana kuʻihao ma mua o ka kuʻihao ʻana.
