Uhlobo 347 / 347H insimbi engagqwali iyizinga le-austenitic lensimbi ye-chromium, equkethe i-columbium njengento eqinisayo. I-Tantalum nayo ingangezwa ukuze kuzuzwe ukuzinzisa. Lokhu kuqeda imvula ye-carbide, kanye nokugqwala kwe-intergranular kumapayipi ensimbi. Amapayipi ensimbi engagqwali angu-347 / 347H anikezela ngezakhiwo ezikhuphukayo nezigqamuka ingcindezi kunebanga elingu-304 no-304L. Lokhu kubenza bafanelekele ukuchayeka ekwaziseni kanye nokugqwala kwe-intergranular. Ngaphezu kwalokho, ukufakwa kwe-columbium kuvumela amapayipi angu-347 ukuba abe nokuphikiswa okuhle kakhulu kokugqwala, okungaphezu kwalokho kwamapayipi ensimbi engagqwali angu-321. Kodwa-ke, insimbi engu-347H ithatha indawo ephakeme yekhabhoni yokwakheka kwepayipi lensimbi engagqwali ebangeni 347. Ngakho-ke, amashubhu ensimbi angu-347H anikeza izinga lokushisa eliphezulu elithuthukisiwe kanye nezakhiwo ezinwabuzelayo.
