Te Hiko Te Whakamahana Te Maamaa Te Hiko
W607
GB/T E5015-G
AWS A5.5 E7015-G
Whakaahuatanga: Ko te W607 he hiko hiko iti-mahana me te paninga konutai iti-waiwai.Whakamahia te DCEP (te hiko tika o naianei) ka taea te paihere ki nga waahi katoa.He pai te kaha o te paheketanga o te whakarewa i te -60°C.
Taupānga: Whakamahia mō te fehokotaki'anga maitai pāmahana iti pērā i 09MnD.
Te hanganga matū o te whakarewa whakarewa(%):
C | Mn | Si | Ni | S | P |
≤0.08 | ≤1.65 | ≤0.60 | 0.50 ~ 2.50 | ≤0.020 | ≤0.025 |
Nga ahuatanga miihini o te whakarewa whakarewa:
Tuemi whakamatautau | Te kaha tensile Mpa | Te kaha tuku Mpa | Te whakaroa % | Uara pānga (J) -60 ℃ |
Ka whakamanahia | ≥490 | ≥390 | ≥22 | ≥27 |
Ko te ihirangi hauwai whakamaoritanga o te konganuku kua penapena: ≤6.0mL/100g (tikanga glycerin) ranei ≤10mL/100g (tikanga chromatography hau ranei)
Tirohanga X-ray: Ko taku tohu

Panui:
1. Me tunuhia te electrode mo te 1 haora i 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;
3. Ka taea te whakamahana i te waahanga kua paiherea mo te 150°C i mua i te whakapiri kia kore ai e pakaru.
