Ala Alloy Steel Welding Electrode
J707
GB/T E7015-D2
AWS E10015-D2
Description: J707 bụ obere alloy elu-ike ígwè electrode na ala-hydrogen sodium mkpuchi.Jiri DCEP (electrode ziri ezi dị ugbu a), enwere ike ịgbanye ya n'ọnọdụ niile.Mgbe ọ dị mkpa, welded nwere ike preheated tupu ịgbado ọkụ na tempered mgbe ịgbado ọkụ.
Ngwa: tumadi eji maka ịgbado ọkụ 15MnMoV, 14MnMoVB, 18MnMoNb na ndị ọzọ ala alloy ígwè owuwu.The welded Ọdịdị nwere ike na-arụ ọrụ n'okpuru ọnọdụ nke ịgbado ọkụ ma ọ bụ tempering (500 ~ 650 ℃).
