A242
GB/T E317-16
AWS A5.4 E317-16
Whakaahuatanga: Ko te A242 he iti-waro Cr19Ni13Mo3 hiko hiko me te paninga titanium-calcium.Ka taea te whakamahi mo te AC me te DC me te mahi tino pai.He nui ake te molybdenum o te konganuku kua whakatakotohia i te A202, he pai ake te aukati i te waikura ki nga waikawa kore-whakaora, penei i te waikawa sulfuric, te waikawa pungatara, te waikawa phosphoric me te waikawa waro.He painga pai ano hoki ki te pirau poka.
Taupānga: Ka whakamahia mo te whakapiri i nga momo taonga kowiri tira tae atu ki te maitai hiato me te rino rereke.
Te hanganga matū o te whakarewa whakarewa(%):
| C | Mn | Si | Cr | Ni | Mo | Cu | S | P |
| ≤0.08 | 0.5 ~ 2.5 | ≤0.90 | 18.0 ~ 21.0 | 12.0 ~ 14.0 | 2.0 ~ 4.0 | ≤0.75 | ≤0.030 | ≤0.040 |
Nga ahuatanga miihini o te whakarewa whakarewa:
| Tuemi whakamatautau | Te kaha tensile Mpa | Te whakaroa % |
| Ka whakamanahia | ≥550 | ≥25 |
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 150 ℃ i mua i te mahi weld;
2. Na te mea he iti te hohonu o te urunga i te wa e whakahiato ana i te AC, me whakamahi te mana hiko DC kia kaha ake ai te kuhu.kia kaua hoki e nui rawa te au ki te karo i te whero o te rakau whakapiri.
