Umfanekiso oPhambili weFlux-Cored Wire EC410NiMo
  • Intambo ene-Flux-Cored EC410NiMo

Intambo ene-Flux-Cored EC410NiMo

Inkcazo emfutshane:

I-EC410NiMo yintambo ye-martensitic stainless steel flux-core ene-chemical composition equlethe i-11.0 – 12.5% ​​Cr, 4.0 – 5.0% Ni, kunye ne-0.40 – 0.70% Mo.

Iinkcukacha zeMveliso

Iithegi zeMveliso

Umgangatho ohambelanayo

GB/T 17853-2018 TS410NiMo-FC11

I-AWS A5.22M-2012 E410NiMoT1-1

Izinto ezilinganayo: 13Cr-4Ni (EN1.4313/UNS S41500)

Inkcazo

I-EC410NiMo yintambo ye-martensitic stainless steel flux-core ene-chemical composition equlethe i-11.0 – 12.5% ​​Cr, 4.0 – 5.0% Ni, kunye ne-0.40 – 0.70% Mo. Ifanelekile kuzo zonke iindawo.ukuwelda kwe-arc ene-flux-core(FCAW) ene-arc ezinzileyo, ukuchitheka okuncinci, kunye nokungasuswa kakuhle kwe-slag. Isinyithi esigciniweyo sinokumelana nokuguguleka okuhle, ukumelana nokuqhekeka, kunye neempawu zoomatshini. Kucetyiswa ukufudumeza kwangaphambili kwi-150 - 260℃, kwaye unyango lobushushu emva kokuwelda (PWHT) kwi-590 ~ 620℃ iyure e-1 (kulandele ukupholisa umoya, i-AC) luyafuneka emva kokuwelda.

Isicelo

Ilungele ukuwelda intsimbi ye-ASTM CA6NM kunye neentsimbi zochungechunge lwe-13%Cr – 4%Ni. Isetyenziselwa ukulungisa ii-hardfacing ze-crane rails, ii-printing rollers, ii-steel shafts, ii-hydropower components ezigutyungelwe yi-cavitation, kunye neendawo zesakhiwo ezifuna ukugqwala kunye nokumelana nokuguguleka.

Isaziso

1. Bhaka i-electrode kwi-300℃ kangangeyure ngaphambi kokuba uyisebenzise ukususa umswakama.

2.Coca umhlwa, ioyile, kunye nokufuma kumphezulu wesinyithi osisiseko; sebenzisa umsebenzi omfutshane we-arc kwiintsimbi ezimxinwa ze-weld.

3. I-PWHT kufuneka yenziwe ngoko nangoko emva kokuwelda ukuze kuthintelwe ukuqhekeka.
