A407
GB/T E310-15
AWS A5.4 E310-15
Whakaahuatanga: A407 he Cr26Ni21 parakore austenitic kowiri tira hiko me te iti hauwai konutai paninga.Whakamahia te DCEP (te hiko tika o naianei) ka taea te paihere ki nga waahi katoa.Ko te konganuku kua penapena he pai te aukati waiora i raro i nga ahuatanga o te pāmahana teitei o te 900 ~ 1100 ℃.I te mea he austenite parakore te konganuku kua penapena, kaore i te pai te parenga kapiti waiariki ki tera o te hanganga matarua.
Taupānga: Ka whakamahia mo te whakapiri i te ahua o te kowiri tira wera-wera, te kowiri tira me te rino rereke, ka taea hoki te whakamahi mo nga hanganga maitai pera i te Cr5Mo, Cr9Mo, Cr13 me Cr28 me te kaha kaha.
Te hanganga matū o te whakarewa whakarewa(%):
| C | Mn | Si | Cr | Ni | Mo | Cu | S | P |
| 0.08 ~ 0.20 | 1.0 ~ 2.5 | ≤0.75 | 25.0 ~ 28.0 | 20.0 ~ 22.5 | ≤0.75 | ≤0.75 | ≤0.030 | ≤0.030 |
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） | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| Waeherehere o naianei （A） | 25 ~ 50 | 50 ~ 80 | 80 ~ 110 | 110 ~ 160 | 160 ~ 200 |
Panui: Me tunu te hiko mo te 1 haora i te 250 ℃ i mua i te mahi fehokotaki.
