347/347H Chitsulo chosapanga dzimbiri

Aloyi 347 ndi chitsulo chokhazikika, cha austenitic, chromium chokhala ndi columbium chomwe chimaganizira kutha kwa mpweya wa carbide, motero kuphulika kwa intergranular. Aloyi 347 imayenderana ndi kuchuluka kwa chromium ndi tantalum ndipo imapereka mphamvu zowononga kwambiri komanso zophulika kuposa aloyi 304 ndi 304L, zomwe zitha kugwiritsidwanso ntchito pakuwonetsa komwe kukhudzidwa ndi dzimbiri lamkati limadetsa nkhawa. Aloyi 347H ndi mawonekedwe apamwamba a carbon a Aloyi 347ndipo amawonetsa kutentha kwakukulu ndi zokwawa.
Makhalidwe

• Kupsinjika kwakukulu ndi kuphulika kwamphamvu poyerekeza ndi 304
• Zabwino pa ntchito yotentha kwambiri
• Amagonjetsa kukhudzidwa ndi nkhawa za intergranular corrosion
• Ikhoza kugwiritsidwa ntchito pa kutentha kwakukulu
• Chifukwa cha kukhazikika zinthu zimapereka kukana kwa dzimbiri bwino poyerekeza ndi 304/304L

• Chemical Processing
• Zida Zopangira Chakudya ndi kusungirako
• Petroleum Refining madzimadzi othandizira ang'onoang'ono mayunitsi, polythionic acid service

Aloyi 347 zitsulo zosapanga dzimbiri mbale zimasonyeza zabwino zonse dzimbiri kukana ngati 304. Anapangidwa kuti ntchito mu chromium carbide mpweya siscope ndi 800 - 1500 ° F (427 - 816 ° C) kumene kaloyi wosagwirizana monga 304 ndi intergranular. kuwukira. Pakutentha uku, kukana kwa chitsulo chosapanga dzimbiri kwa Aloyi 347 ndikwabwino kuposa mbale ya Aloyi 321 yachitsulo chosapanga dzimbiri. Aloyi 347 imagwiranso ntchito bwino kuposa Aloyi 321 pamalo otsekemera kwambiri mpaka 1500 ° F (816 ° C). Aloyi angagwiritsidwe ntchito ngati gawo la nitric solution; ambiri kuchepetsedwa organic zidulo pa kutentha zolimbitsa ndi asidi phosphoric koyera pa kutentha otsika ndi 10% kuchepetsedwa njira pa kutentha kwambiri. Aloyi 347 chitsulo chosapanga dzimbiri mbale amakana polythionic asidi nkhawa dzimbiri kusweka mu ntchito hydrocarbon. Itha kugwiritsidwanso ntchito mu njira za chloride kapena fluoride zopanda caustic pakutentha koyenera. Aloyi 347 zitsulo zosapanga dzimbiri sizigwira ntchito bwino muzitsulo za kloridi, ngakhale pang'ono, kapena sulfuric acid.
