density ntawm 310 stainless hlau

Alloy 310 yog dab tsi?

Alloy 310 (UNS S31000) yog austenitic stainless hlau tsim los rau siab -kub corrosion kuj. Alloy 310S (UNS S31008) yog ib qho qis -carbon version uas txhim kho weldability thiab txo qhov kev pheej hmoo ntawm carbide nag lossis daus thaum vuam. Alloy 310H (UNS S31009) muaj cov pa roj carbon ntau dua, muab kev nkag siab zoo dua ntawm qhov kub thiab txias. Feem ntau, cov nplej loj thiab cov ntsiab lus carbon ntawm daim ntawv tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm 310S thiab 310H.

 

Dab tsi yog cov yam ntxwv ntawm 310 stainless hlau?

310 stainless hlau muaj 25% chromium thiab 20% npib tsib xee, muab nws tsis tshua muaj oxidation thiab corrosion kuj. Qib 310S yog qib qis -carbon version, ua rau nws tsis tshua muaj embrittlement thiab rhiab heev thaum siv. Lub siab chromium thiab cov ntsiab lus nickel nruab nrab ua rau cov hlau no tsim nyog rau kev txo cov cua daj cua dub uas muaj hydrogen sulfide. Lawv tau dav siv nyob rau hauv nruab nrab carburizing cua, xws li cov uas muaj nyob rau hauv petrochemical ib puag ncig. Rau qhov xav tau ntau dua carburizing cua, lwm cov cua sov- yuav tsum tau xaiv cov alloys.

 

310 stainless hlau muaj pes tsawg leeg

310 stainless hlau yog qhov siab -kub austenitic stainless hlau nrog cov ntsiab lus ntawm kwv yees li 25% chromium, 20% npib tsib xee, thiab cov hlau seem, nrog rau cov ntsiab lus siab tshaj ntawm 0.25%. Cov qib qis- carbon hom, 310S, muaj cov ntsiab lus siab tshaj plaws ntawm 0.08% thiab feem ntau siv rau hauv cov ntawv thov uas yuav tsum tau ua kom yooj yim dua.

Corrosion Resistance:

310/310S steel feem ntau tsis siv nyob rau hauv cov kua corrosive ib puag ncig, txawm hais tias nws cov ntsiab lus chromium thiab npib tsib xee ua rau nws tiv taus corrosion ntau dua li 304 steel. Cov hlau no tsis muaj molybdenum, yog li nws tsis kam rau pitting corrosion kuj tsis zoo.

Dab tsi yog qhov ntom ntawm 310 stainless hlau?

Qhov ntom ntawm 310 stainless hlau yog kwv yees li 0.285 txog 0.290 lb / in³ lossis 7.84 txog 8.03 g / cm³. Tus nqi no tuaj yeem sib txawv me ntsis nyob ntawm qhov tshwj xeeb alloy muaj pes tsawg leeg thiab kub.

 

Dab tsi yog qhov kub thiab txias rau 310 stainless hlau?

310 stainless hlau muaj cov ntsiab lus melting ntawm kwv yees li 1354-1402℃(2470-2555℉), ua rau nws tsim nyog rau kev siv kub. Raws li kev siv tas mus li, nws cov oxidation kuj tuaj yeem ncav cuag li 1050℃(1922℉). Nws qhov kev txwv tseem ceeb nyob hauv kev tsim ntawm σ theem, uas tuaj yeem ua rau cov khoom siv los ua embritted ntawm 650-900℃(1202-1652℉).
