I-AISI/SUS 309 STAINLESS STEEL COIL/SHEET

Izinsimbi ezingagqwali zingama-high-alloy steels anokumelana nokugqwala okuphezulu uma kuqhathaniswa nezinye izinsimbi ngenxa yokuba khona kwenani elikhulu le-chromium. Ngokusekelwe esakhiweni sabo se-crystalline, baphinde bahlukaniswe ngezinsimbi ze-ferritic, austenitic, ne-martensitic.

I-Grade 309 insimbi engagqwali inokumelana nokugqwala okuphezulu namandla uma iqhathaniswa nensimbi engagqwali engu-304. Iminingwane elandelayo inikezela ngemininingwane yezinga lama-309 lensimbi engagqwali.

Izakhiwo Ezijwayelekile

I-alloy 309 (UNS S30900) iyinsimbi engagqwali ye-austenitic eyakhelwe ukusetshenziswa ezindaweni ezishisa kakhulu zokumelana nokugqwala. Ingxubevange imelana ne-oxidation kuze kufike ku-1900°F (1038°C) ngaphansi kwezimo ezingezona umjikelezo. Ukuhamba ngebhayisikili okushisayo okuvamisile kunciphisa ukumelana ne-oxidation kufinyelele cishe ku-1850°F (1010°C).

Ngenxa yokuqukethwe kwe-chromium ephezulu kanye ne-nickel ephansi, i-Alloy 309 ingasetshenziswa kusibabule esiqukethe i-atmosphere kufika ku-1832°F (1000°C). Ingxubevange ayinconywa ukuthi isetshenziswe ezindaweni ezishisa kakhulu i-carburizing ngoba ikhombisa ukumelana okusesilinganisweni kokumuncwa kwekhabhoni. I-alloy 309 ingasetshenziswa ekufakweni kwe-oxidizing kancane, i-nitriding, ukufaka usimende kanye nezinhlelo zokusebenza zamabhayisikili ezishisayo, noma kunjalo, izinga lokushisa eliphezulu lesevisi kufanele lincishiswe.

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-309S (UNS S30908) 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.

I-alloy 309 ingashiselwa kalula futhi isetshenzwe ngezinqubo ezijwayelekile zokwenziwa kwezitolo.
