Ukuqhathaniswa Phakathi Kwamapayipi Ensimbi Engagqwali angu-304H nama-304

— Amakhono Okukhiqiza Ensimbi Ye-Womic Nezixazululo Zomkhiqizo

1. Uhlolojikelele Lomkhiqizo

I-Womic Steel ingumkhiqizi ohamba phambili wamapayipi ensimbi engagqwali esezingeni eliphezulu, anikezela ngawo womabili304Hfuthi304amapayipi ensimbi engagqwali ngokuhambisana nezindinganiso ezinkulu zamazwe ngamazwe, okuhlanganisa:

lI-ASTM A312/A213/A269/A358

lI-ASME SA312 / SA213

lEN 10216-5 / EN 10297-2

lI-JIS G3459 / ISO 9329-4

lI-GB/T 14976 / GB/T 13296

I-304H ne-304 zombili izinsimbi ezingenasici ze-austenitic, kodwa zakhelwe izimo zokusebenza ezihlukile—I-304H ihamba phambili kusevisi yezinga lokushisa eliphezulu, ngenkathiI-304 inikeza ukumelana nokugqwala okuphezulu kanye nokushiselaezinhlelweni ezijwayelekile.

2.Ukwakheka Kwamakhemikhali

 

Isici	304 Insimbi Engagqwali	304H Insimbi Engagqwali
Ikhabhoni (C)	≤ 0.08%	0.04% - 0.10%
I-Chromium (Cr)	18.0% - 20.0%	18.0% - 20.0%
I-Nickel (Ni)	8.0% - 11.0%	8.0% - 11.0%
I-Manganese (Mn)	≤ 2.00%	≤ 2.00%
I-silicon (Si)	≤ 1.00%	≤ 1.00%
I-Phosphorus (P)	≤ 0.045%	≤ 0.045%
Isibabule (S)	≤ 0.030%	≤ 0.030%
I-nitrogen (N)	≤ 0.10%	≤ 0.10%
Insimbi (Fe)	Ibhalansi	Ibhalansi

Iokuqukethwe kwekhabhoni ephezuluku-304H kuthuthukisa imvula ye-carbide (Cr₂₃C₆), ibe ngconoukumelana nokukhasa kanye namandla okushisa aphezulu. Okuqukethwe kwekhabhoni ephansi kwe-304 kulungeleizakhiwo ezishiselwekudinga ukumelana nokugqwala okuhle kwe-intergranular.

 

3. Ububanzi Bosayizi Nezinhlobo Zomkhiqizo

I-Womic Steel inikezela ngezinhlobo eziningi zamapayipi ensimbi engagqwali enzelwe izimboni, ezokwakha, nezinhlelo zengcindezi:

Amapayipi Angenamthungo:
