Bayani: R407 wani lantarki ne na ƙarfe mai jure zafi mai laushi wanda ke da rufin sodium mai ƙarancin hydrogen wanda ke ɗauke da 2.5% Cr – 1% Mo. Yi amfani da DCEP (mai nuna wutar lantarki kai tsaye) kuma ana iya haɗa shi a kowane matsayi. Dole ne a kunna walda zuwa 200 ~ 300°C kafin walda.
Aikace-aikace: Ana amfani da shi don walda bututun mai mai zafi da matsin lamba mai yawa waɗanda zafin aiki bai wuce 550°C ba, injinan sinadarai na roba, kayan fashewar mai, da sauransu.
Sinadarin sinadarai na ƙarfen walda(%):

| An Garanti | ≥590 | ≥490 | ≥15 | ≥47 |
| An gwada | 600 ~ 680 | ≥500 | 18 ~ 21 |
Yaɗuwar sinadarin hydrogen a cikin ƙarfe da aka ajiye: ≤4.0mL/100g (hanyar glycerin)
Duba X-ray: I maki
Shawarar da ake bayarwa:
| Diamita na sanda (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
| Walda na Wuta (A) | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Sanarwa:
1. Dole ne a gasa wutar lantarki na tsawon awa 1 a zafin 350℃ kafin a fara aiki da walda;
2. Yana da mahimmanci a tsaftace tsatsa, ma'aunin mai, ruwa, da ƙazanta a kan sassan walda kafin walda.
