Izigqubuthelo zomngxuma wentsimbi

Izigqubuthelo zomngxuma wentsimbiubukhulu becala zenziwe ngentsimbi ye-ductile cast.

Isigqubuthelo somngxuma wentsimbi sinezi nzuzo:

ngenxa yamandla aphezulu kunye nokuqina okuhle kwentsimbi ye-ductile, isigqubuthelo somngxuma wentsimbi simalungaI-30% ikhaphukhaphungaphezu kwesigqubuthelo somngxuma wentsimbi esingwevu sohlobo olufanayo.

Iimpawu zesigqubuthelo somngxuma wentsimbi:

① Ukuqina okuhle. 

Ixabiso leempembelelo lingaphezulu kwamaxesha ali-10 leyentsimbi engwevu.

②Ukuxhathisa okuqinileyo kwe-corrosion.

Uvavanyo lokutya kokutshiza kwamanzi, umhlwa weentsuku ezingama-90 yi-1/40 kuphela yombhobho wentsimbi, yi-1/10 yombhobho wentsimbi engwevu.Ubomi benkonzo ngamaxesha angama-2 kunombhobho wentsimbi engwevu kunye namaxesha ama-5 kunombhobho wensimbi oqhelekileyo.

③Iplastiki enhle.

ubude ≥7%, kufana nentsimbi yekhabhoni ephezulu.Kodwa ulwakhiwo lwentsimbi engwevu lumalunga neqanda.

④Amandla aphezulu.

Amandla e-tensile OB ≥420MPa, isivuno samandla OS ≥300MPa, amaxesha amathathu ezinto zentsimbi ezingwevu.
