Low otutu Irin Welding Electrode
W707
GB/T E5015-G
Aws A5.5 E7015-G
Apejuwe: W707 jẹ elekiturodu irin-iwọn otutu ti o ni iwọn-kekere ti iṣu soda iṣuu soda.Lo DCEP (taara ti isiyi elekiturodu rere) ati ki o le welded ni gbogbo awọn ipo.Irin ti a fi pamọ si tun ni ipa lile to dara ni -70°C.
Ohun elo: Lo fun alurinmorin kekere, irin bi 2.5Ni.
Apapọ kemikali ti irin weld (%):
