Kowiri tira fehokotaki'angaHikohiko
AF2553-16
GB/T E2553-16
AWS A5.4 E2553-16
Whakaahuatanga: Ko te AF2553-16 he hauota-kei roto i te taarua kowiri tira hiko me te paninga titanium-calcium.Ka taea te whakamahi mo te AC me te DC me te mahi tino pai.Na te mea kei roto i te molybdenum me te hauota, he iti rawa te waro, he pai te atete kapiti me te parenga waikura o te konganuku penapena, ina koa te awangawanga o te waikura.
Taupānga: Kei te whakamahia te reira mo te fehokotaki'anga matarua kowiri tira ki te ihirangi chromium o e pā ana ki 25%, pērā i 022Cr25Ni7Mo4N, 03Cr25Ni6Mo3Cu2N, UNS 32550 (Alloy255), etc.
Te hanganga matū o te whakarewa whakarewa(%):
| C | Mn | Si | Cr | Ni | Mo | Cu | N | S | P |
| ≤0.06 | 0.5 ~ 1.5 | ≤1.0 | 24.0 ~ 27.0 | 6.5 ~ 8.5 | 2.9 ~ 3.9 | 1.5 ~ 2.5 | 0.10 ~ 0.25 | ≤0.030 | ≤0.040 |
Nga ahuatanga miihini o te whakarewa whakarewa:
| Tuemi whakamatautau | Te kaha tensile Mpa | Te whakaroa % |
| Ka whakamanahia | ≥760 | ≥15 |
O nāianei e taunaki ana:
| Te diameter o te tokotoko （mm） | 2.5 | 3.2 | 4.0 | 5.0 |
| Waeherehere o naianei （A） | 50 ~80 | 80 ~ 110 | 110 ~ 160 | 160 ~ 200 |
Panui:
1. Me tunuhia te electrode mo te 1 haora i te taha o te 250 ℃ i mua i te mahi fehokotaki'anga;
2. Whakamahia te kaha o te hiko DC kia taea, kia kaua e nui rawa te waa ki te karo i te whero o te rakau whakapiri;
3. I mua i te whakapiri, tangohia te hinu, te waikura, te tauine, te makuku me etahi atu mea poke i runga i te mata o nga waahanga whakapiri.
