Na'urar Walda ta Nickel da Nickel Alloy
Ni307-1
GB/T ENi6062
AWS A5.11 ENiCrFe-1
Bayani: Ni307-1 lantarki ne mai tushen nickel wanda ke da ƙarancin rufin hydrogen sodium. Yi amfani da DCEP (mai nuna wutar lantarki kai tsaye). Tunda walda tana ɗauke da Nb, ƙarfen da aka ajiye yana da kyakkyawan filastik da juriya ga tsagewa.
Amfani: Ana amfani da shi don walda ƙarfe na nickel-chromium-iron (kamar UNS N06600, UNS N06601) da kuma saman ƙarfe. Yana da kyawawan halaye na walda na ƙarfe daban-daban. Hakanan ana iya amfani da shi a zafin aiki na 980°C, amma idan zafin ya fi 820°C, juriyar iskar shaka da ƙarfi za su ragu.
Sinadarin sinadarai na ƙarfen walda(%):
| C | Mn | Fe | Si | Cu | Ni | Cr | Nb + Ta | S | P | Wani |
| ≤0.08 | ≤3.5 | ≤11.0 | ≤0.8 | ≤0.5 | ≥62.0 | 13.0 ~ 17.0 | 0.5 ~ 4.0 | ≤0.015 | ≤0.020 | ≤0.50 |
Kayan aikin injiniya na ƙarfe na walda:
| Gwaji abu | Ƙarfin tauri Mpa | Ƙarfin bayarwa Mpa | Ƙarawa % |
| An Garanti | ≥550 | ≥360 | ≥27 |
Shawarar da ake bayarwa:
| Diamita na sanda (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
| Walda na yanzu (A) | 60 ~ 90 | 80 ~ 110 | 110 ~ 150 | 130 ~ 180 |
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.
