Low Alloy Karfe Welding Electrode

J707                               

GB/T E7015-D2

Saukewa: AWS E10015-D2

 

Bayani: J707 shine ƙaramin ƙarfe mai ƙarfi mai ƙarfi na ƙarfe mai ƙarfi tare da murfin sodium low-hydrogen.Yi amfani da DCEP (tabbataccen lantarki na yanzu kai tsaye), kuma ana iya walda shi a duk wurare.A lokacin da ya cancanta, za a iya preheated welding kafin walda da kuma tempered bayan walda.

Aikace-aikace: Yafi amfani da waldi 15MnMoV, 14MnMoVB, 18MnMoNb da sauran low-alloy karfe Tsarin.A welded tsarin iya aiki a karkashin yanayin waldi ko tempering (500 ~ 650 ℃).
