Stainless hlau 309S / 309
Stainless hlau 309S yog cais raws li cov hlau tsis muaj hlau alloy. Nws muaj tsawg nickel nyob rau hauv nws muaj pes tsawg leeg tshaj li hom 310 thiab cov pa roj carbon tsawg dua nws hom 309 counterpart. Cov nickel txo qis tso cai rau kev tiv thaiv zoo dua tiv thaiv hydrogen sulfide, tshwj xeeb tshaj yog thaum kub siab ....

Stainless hlau 309Syog cais raws li ib tug heev alloyed stainless hlau. Nws muaj tsawg nickel nyob rau hauv nws muaj pes tsawg leeg tshaj li hom 310 thiab cov pa roj carbon tsawg dua nws hom 309 counterpart. Cov nickel txo qis tso cai rau kev tiv thaiv zoo dua tiv thaiv hydrogen sulfide, tshwj xeeb tshaj yog thaum kub kub. Tsis tas li ntawd, qhov qis dua ntawm cov pa roj carbon monoxide hauv nws cov muaj pes tsawg leeg muab Stainless Steel 309S siv nyob rau hauv cov cheeb tsam uas kub kub gases yuav ua rau muaj teeb meem. Yog li ntawd, nws yog feem ntau siv rau hauv kev tsim cov tshuab ua kom sov, cov tshuab tso pa tawm thiab cov thawv ntim rau qhov kub thiab txias.
Hom 309S tseem yog tus yam ntxwv los ntawm nws txoj kev tiv thaiv oxidation thiab nkag mus, nrog rau nws muaj peev xwm tiv taus qhov kub thiab txias. Moisten ib puag ncig tsis muaj kev cuam tshuam rau nws, vim muaj ntau ntau ntawm nickel thiab chromium hauv nws cov pleev. Vim li no, nws yog feem ntau siv nyob rau hauv marine ib puag ncig nyob rau hauv qhov chaw ntawm Stainless hlau 304, raws li nws qhia ib tug ntau dua kuj.
Txawm hais tias nws zoo heev weldability, Hom 309S muaj kev nyiam ua haujlwm hnyav.
Stainless hlau 309feem ntau hu ua cov pa roj carbon ntau rau hom 309H. Nws cov qib siab ntawm cov pa roj carbon ntau ua rau muab kev tiv thaiv ntxiv tiv thaiv creep. Nrog rau carbon, hlau, chromium, thiab npib tsib xee ua rau feem ntau ntawm nws cov muaj pes tsawg leeg. Txawm li cas los xij, nws tsis yog qhov txawv uas Hom 309, 309S thiab 309H txhua tus ua tau raws li qhov yuav tsum tau ua rau tag nrho peb qhov sib txawv ntawm Stainless Steel 309 qib.
Ntau yam zoo li 309, Hom 309H muaj kev tiv thaiv siab tiv thaiv oxidation. Nws feem ntau pom muaj nyob rau hauv cov cheeb tsam uas zam oxidation, nrog rau cov cub tawg, cov khoom siv zeb ntawv thiab cov txheej txheem thermal. Nws daim ntawv thov nquag coj hom 309H mus rau hauv kev sib cuag nrog acetic acid thiab citric acid, sulfur dioxide thiab ammonia; concentrated acids yog lwm yam khoom siv. Cov hlau tuaj yeem siv rau hauv ib puag ncig uas muaj qhov kub thiab txias, thiab tseem muaj peev xwm khaws tau ib feem loj ntawm nws lub zog ntawm chav tsev kub ntau dua li cov alloys sib piv.
