I-US 309/309S (UNS S30900/S30908) insimbi

IZINHLOBO  309                           nge       nezinsimbi      nezinsimbi  ne- nickel  nezinsimbi ezingagqwali ezinikeza ukumelana nokugqwala nokumelana nokushisa kanye namandla amahle ekamelweni namazinga okushisa aphakeme. I-Type 309S ifana no-Type 309 ngaphandle kokuqukethwe kwekhabhoni ephansi okwehlisa imvula ye-carbide futhi kuthuthukise ukushisela.

I-alloy 309 ne-309S yaziwa kakhulu ngesevisi yokushisa okuphezulu. Le alloy isebenza kahle ifike ku-2000 °F, ikakhulukazi uma kudingeka ukumelana ne-oxidation. I-309 kanye ne-310 insimbi engagqwali zingabadlali bokushisa okuphezulu phakathi kwamabanga ajwayelekile angenasici atholakala esitokweni sethu. I-nickel ephezulu nokuqukethwe kwe-chromium kanye nesakhiwo sokusanhlamvu esimahhadla kuholela ku:

• Ukumelana okuthuthukisiwe ku-cyclic oxidation
• Ukwanda kokumelana ne-sulfidation
• Amandla okushisa angcono aphakeme
• Ukumelana okuthuthukisiwe kokugqwala kwe-intergranular

I-309S (UNS S30908) insimbi engagqwali inguqulo yekhabhoni ephansi yealloy. Isetshenziselwa ukwenza lula ukwenziwa.

I-309H (UNS S30909) iwukushintshwa kwekhabhoni ephezulu okwenzelwe ukumelana okuthuthukile. Izikhathi eziningi usayizi wokusanhlamvu nokuqukethwe kwekhabhoni yepuleti kungahlangabezana kokubili izimfuneko ze-309S kanye ne-309H. Uma ishisisa phakathi kuka-1202 – 1742°F (650 – 950°C) ingxubevange ingaphansi kwemvula yesigaba se-sigma. Ukwelashwa kwe-annealing yesisombululo ngo-2012 – 2102°F (1100 – 1150°C) kuzobuyisela izinga lokuqina. I-alloy 309 ingashiselwa kalula futhi isetshenzwe ngezinqubo ezijwayelekile zokwenziwa kwezitolo.
