I-Womic Steel – Izisombululo zePipe yeNtsimbi Engagqwaliyo ye-347H eziSebenza ngokuPhezulu

1. Isishwankathelo seMpahla

Umbhobho wentsimbi engagqwaliyo ye-347H yintsimbi engagqwaliyo ye-austenitic ene-carbon ephezulu ezinzileyo eyaziwa ngamandla ayo aphezulu obushushu, ukudityaniswa kakuhle, kunye nokumelana okugqwesileyo nokugqwala kwe-intergranular. Ukongezwa kwe-niobium (Nb) kuphucula amandla okuqhekeka kwaye kuthintele ukuna kwe-chromium carbide kwimida yeenkozo, kuqinisekisa ukumelana okuphuculweyo kokuvakalelwa.

2.Ulwakhiwo lweeKhemikhali (Oluqhelekileyo)

3. Iipropati zoomatshini kunye nokugqwala

Iipropati zoomatshini (ASTM A213):
