I-Womic Steel-Intsebenzo ePhezulu ye-347H yeSisombululo seMibhobho yeNsimbi engenaStainless

1. Isishwankathelo seMathiriyeli

I-347H ipayipi yensimbi engenasici yi-carbon niobium-stabilized austenitic stainless steel stabilized eyaziwa ngamandla ayo aphezulu obushushu obuphezulu, i-weldability egqwesileyo, kunye nokumelana okubalaseleyo kwi-corrosion intergranular. Ukongezwa kwe-niobium (Nb) kuphucula amandla e-creep kwaye kuthintele imvula ye-chromium carbide ecaleni kwemida yeenkozo, iqinisekisa ukuxhathisa okongeziweyo kwi-sensitization.
