Haʻahaʻa Alloy Steel Weld Electrode
J556Fe
GB/T E5518-G
AWS E8018-G
Hōʻike: J556fe he haʻahaʻa haʻahaʻa kila electrode me ka hao pauka a me ka haʻahaʻa hydrogen.Hiki ke hoʻohana ʻia ʻo AC a me DC, a hiki ke welded i nā kūlana āpau.
Noi: Hoʻohana ʻia no ka wiliwili ʻana i ke kila kalapona haʻahaʻa a me nā hale kila hao haʻahaʻa e like me Q390.
ʻO ka hui kemika o ka weld metala(%):
C | Mn | Si | S | P |
≤0.12 | ≥1.00 | ≤0.80 | ≤0.035 | ≤0.035 |
Nā waiwai mīkini o ka weld metala:
Mea ho'āʻo | Ka ikaika tensile Mpa | Hua ikaika Mpa | ʻO ka lōʻihi % | Waiwai hopena (J) -40 ℃ |
Hōʻoiaʻiʻo | ≥540 | ≥440 | ≥17 | ≥27 |
Maʻiʻo hydrogen diffusion o ka metala i waiho ʻia: ≤10.0mL/100g (mercury a i ʻole gas chromatography method)
X-ray inspection: I ka helu
Manaʻo ʻia i kēia manawa:
(mm) Anawaena lāʻau | 2.5 | 3.2 | 4.0 | 5.0 |
(A) Ke au wiliwili | 70 ~ 110 | 100 ~ 140 | 140 ~ 170 | 190 ~ 240 |
Hoʻolaha:
1. Pono e hoʻomoʻa ʻia ka electrode no 1 hola ma 350 ℃ ma mua o ka hana wili;
2. He mea nui e hoʻomaʻemaʻe i ka ʻōpala, ka aila unahi, ka wai, a me nā haumia ma nā ʻāpana wili ma mua o ka wili ʻana;
3. E hoʻohana i ka hana pōkole i ka wā e wili ai.Pono ke ala wiliwili haiki.
