Nickel daNa'urar Walda ta Nickel Alloy
Ni307-4
GB/T ENi6093
AWS A5.11 ENiCrFe-4
Bayani: Ni307-4 lantarki ne mai tushen nickel tare da rufin sodium mai ƙarancin hydrogen. Yi amfani da DCEP (electrode na yanzu kai tsaye).yana da kyakkyawan aikin walda tare da ƙonewa mai ƙarfi, ƙarancin fesawa, da sauƙin cire slag,
da kuma kyakkyawan walda.
Aikace-aikace: Ana amfani da shi don walda ƙarfe na nickel-chromium-iron, kamar Ni600, Ni800/800H da makamantansu ko superalloys waɗanda aka yi da nickel tare da zafin aiki na 900 ° C. Hakanan ana iya amfani da shi don ƙananan ƙarfe waɗanda ke ɗauke da Ni3% ~ 9%, kamar ASTM A333, A334, A353, A522. Hakanan ana iya amfani da walda na A553 don walda ƙarfe daban-daban tsakanin Mo400, Ni825, bakin ƙarfe da ƙaramin ƙarfe mai ƙarfe.
Sinadarin sinadarai na ƙarfen walda(%):
| C | Mn | Fe | Si | Ni | Cr | Mo | Nb + Ta | S | P |
| ≤0.20 | 1.0 ~ 5.0 | ≤12.0 | ≤1.0 | ≥60.0 | 13.0 ~ 17.0 | 1.0 ~ 3.5 | 1.0 ~ 3.5 | ≤0.015 | ≤0.020 |
Kayan aikin injiniya na ƙarfe na walda:
| Gwaji abu | Ƙarfin tauri Mpa | Ƙarfin bayarwa Mpa | Ƙarawa % |
| An Garanti | ≥650 | ≥360 | ≥18 |
Shawarar da ake bayarwa:
| Diamita na sanda (mm) | 2.5 | 3.2 | 4.0 |
| Walda na yanzu (A) | 60 ~ 90 | 80 ~ 110 | 110 ~ 150 |
Sanarwa:
1. Dole ne a gasa wutar lantarki na tsawon awa 1 a kusan 300℃ kafin a fara aikin walda;
2. Yana da mahimmanci a tsaftace tsatsa, mai, ruwa, da ƙazanta a kan sassan walda kafin a yi walda. Yi ƙoƙarin amfani da ɗan gajeren baka don walda.
