US 309 / 309S (UNS S30900 / S30908) ibyuma

UBWOKO 309 NA 309S ni austenitis chromium-nikel ibyuma bitagira umuyonga bitanga imbaraga zo kurwanya ruswa no kurwanya ubushyuhe hiyongereyeho imbaraga nziza mubyumba n'ubushyuhe bwo hejuru. Ubwoko 309S burasa nubwoko 309 usibye ibirimo karubone yo hasi igabanya imvura ya karbide kandi igateza imbere gusudira.

Alloy 309 na 309S izwi cyane muri serivisi yubushyuhe bwo hejuru. Iyi mavuta ikora neza kugeza 2000 ° F, cyane cyane iyo hakenewe kurwanya okiside. 309 na 310 ibyuma bitagira umwanda nibikorwa byambere byubushyuhe bwo hejuru mubyiciro bisanzwe bitagira umwanda biboneka kububiko bwacu. Nikel nyinshi hamwe na chromium hamwe nuburyo bunini bwimbuto bivamo:

• Kunoza kurwanya okiside ya cyclicale
• Kongera imbaraga zo kurwanya sulfidation
• Imbaraga zubushyuhe bwo hejuru
• Kunoza kunanirwa kwangirika kwimitsi

309S (UNS S30908) ibyuma bidafite ingese ni verisiyo ya karubone yo hasi ya alloy. Ikoreshwa muburyo bworoshye bwo guhimba.

309H (UNS S30909) ni ihinduka ryinshi rya karubone ryateguwe kugirango ryongere imbaraga zo guhangana n’ibikurura. Ingero nyinshi ingano yubunini hamwe na karubone yibisahani irashobora kuba yujuje ibisabwa 309S na 309H. Iyo hashyushye hagati ya 1202 - 1742 ° F (650 - 950 ° C) ibishishwa biterwa nubushyuhe bwa sigma. Umuti uhuza imiti muri 2012 - 2102 ° F (1100 - 1150 ° C) uzagarura urwego rukomeye. Alloy 309 irashobora gusudwa byoroshye no gutunganywa nuburyo busanzwe bwo guhimba amaduka.
