Iti Alloy Steel Welding Hiko
J557SLA, J557SLB
GB/T E5515-G
AWS E8015-G
Whakaahuatanga: Ko te konutai hauwai iti e hipokina ana te hiko motuhake mo te maitai aluminized.Whakamahia te DCEP (te hiko tika o naianei), ka taea te paihere ki nga waahi katoa me te mahi pewa poto.Ka taea e J557SLA te paihere tika me te kore e tango i te paparanga aluminized i runga i te mata o te haehae i mua i te whakapiri.Engari me tango e te J557SLB te paparanga aluminized i runga i te mata haehae i mua i te whakapiri.
Taupānga: Kei te whakamahia mō te fehokotaki'anga i te hanganga maitai aluminized i raro i te reo waikura o hauwai sulfide, whanariki, haukinia, haukinia bicarbonate me te hauwai hauota ki te pāmahana mahi i raro i 540°C.Pērā i ngā paipa kōhua, taputapu para hinu, taputapu tongi me nga paipa mamaoa, aha atu.
Te hanganga matū o te whakarewa whakarewa(%):
C | Mn | Si | Cr | Mo | Al | S | P |
≤0.12 | 0.50 ~ 0.90 | ≤0.50 | ≈0.80 | ≥0.20 | ≤0.055 | ≤0.035 | ≤0.035 |
Nga ahuatanga miihini o te whakarewa whakarewa:
Tuemi whakamatautau | Te kaha tensile Mpa | Te kaha tuku Mpa | Te whakaroa % | Uara pānga (J) Pūnoa Temp. |
Ka whakamanahia | ≥540 | ≥440 | ≥17 | ≥49 |
Ko te ihirangi hauwai whakamaoritanga o te konganuku penapena: ≤6.0mL/100g (tikanga glycerin)
Tirohanga X-ray: Ko taku tohu
O nāianei e taunaki ana:
(mm) Te diameter o te tokotoko | 2.5 | 3.2 | 4.0 | 5.0 |
(A) Waeherehere o naianei | 50 ~ 80 | 80 ~ 110 | 130 ~ 170 | 160 ~ 200 |
Panui:
1. Me tunuhia te electrode mo te 1 haora i te taha o te 350 ℃ i mua i te mahi whakapiri;
2. He mea nui ki te horoi i te waikura, te unahi hinu, te wai, me nga poke i runga i nga waahanga whakapiri i mua i te whakapiri.
