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

MATYPES 309 AND 309S austenitic chromium-nickel simbi dzisina kusimba dzinopa kusaita ngura uye kusapisa kupisa pamwe nesimba rakanaka mumba uye tembiricha dzakakwirira. Type 309S yakafanana neType 309 kunze kwekabhoni yakaderera inodzikisira kunaya kwecarbide uye kunatsiridza kucheneruka.

Alloy 309 uye 309S inonyanya kuzivikanwa nepamusoro tembiricha sevhisi. Iyi alloy inoshanda zvakanaka kusvika ku2000 ° F, kunyanya kana oxidation kuramba ichidikanwa. 309 uye 310 Stainless simbi ndivo vatambi vekutanga tembiricha yepamusoro pakati peakajairwa Stainless mamakisi anowanikwa kubva kustock yedu. Yakakwira nickel uye chromium zvemukati uye yakaomarara chimiro chezviyo zvinoguma ne:

• Kuvandudza kupikisa kune cyclic oxidation
• Kuwedzera kushorwa kune sulfidation
• Zvirinani kusimba kwekushisa kwepamusoro
• Kuvandudza kupikisa kune intergranular corrosion

309S (UNS S30908) simbi isina tsvina ndiyo yakaderera kabhoni vhezheni yealloy. Inoshandiswa nyore nyore kugadzira.

309H (UNS S30909) ndeye yakakwira kabhoni gadziriso yakagadziridzwa kuti iwedzere kuramba. Kazhinji kazhinji saizi yezviyo uye kabhoni yemukati mundiro inogona kusangana nezvose 309S uye 309H zvinodiwa. Kana ichipisa pakati pe1202 - 1742 ° F (650 - 950 ° C) alloy iri pasi pe sigma phase precipitation. A solution annealing treatment pa 2012 – 2102°F (1100 – 1150°C) inodzoreredza dhigirii rekuomarara. Alloy 309 inogona kusungirirwa zviri nyore uye kugadziriswa neyakajairwa chitoro chekugadzira maitiro.
