Kev Tiv Thaiv Kev Xeb:
Kev tiv thaiv xeb hauv cov chaw oxidizing yog qhov tshwm sim ntawm 18 txog 19% chromium uas 304 alloys muaj.
Kev tiv taus cov organic acids uas muaj zog nruab nrab yog qhov tshwm sim ntawm 9 txog 11% nickel uas cov hlau 304 muaj.
Qee lub sij hawm, alloy 304L yuav qhia txog qhov corrosion qis dua li cov carbon siab dua Alloy 304; txwv tsis pub, 304, 304L, thiab 304H yuav raug suav hais tias ua haujlwm sib npaug hauv feem ntau qhov chaw corrosive.
Cov hlau nplaum 304L yog qhov zoo dua rau kev siv rau hauv cov chaw uas muaj corrosive txaus kom ua rau muaj kev xeb intergranular ntawm cov welds thiab cov cheeb tsam uas muaj cua sov ntawm cov hlau nplaum uas yooj yim rau kev puas tsuaj.
Kev Tiv Thaiv Kub:
Zoo tiv taus oxidation hauv kev pabcuam tsis tu ncua mus txog 1600 ° F thiab hauv kev pabcuam tas mus li mus txog 1690 ° F.
Tsis pom zoo kom siv 304 tas li ntawm 800-1580 ° F yog tias qhov kev tiv thaiv xeb hauv dej tom qab ntawd tseem ceeb.
Qib 304L tiv taus cov carbide nag thiab tuaj yeem ua kom sov rau hauv qhov kub siab tshaj.
Cov Khoom ntawm 304 Alloy
Cov yam ntxwv ntawm vuam:
Cov yam ntxwv vuam zoo heev; tsis tas yuav tsum tau ua kom sov tom qab vuam thaum vuam cov ntu nyias. Ob qho tseem ceeb xav txog hauv kev tsim cov pob qij txha vuam hauv austeniticcov hlau tsis xebyog:
kev tiv thaiv corrosion
kev zam ntawm kev tawg
Kev Ua - Kev Tsim Kub:
Yuav kom forge, cua sov sib npaug rau 2100 / 2300 ° F
Tsis txhob ua kom kub tshaj 1700 ° F
Kev forging tuaj yeem ua kom txias los ntawm huab cua yam tsis muaj kev phom sij ntawm kev tawg
Kev Ua - Kev Tsim Txias:
Nws cov qauv austenitic tso cai rau nws kom rub tob yam tsis muaj kev kub hnyiab nruab nrab, Ua qhov no yog qib stainless hlau xaiv hauv kev tsim cov dab dej, cov khoom siv khoob thiab cov lauj kaub.
Cov qib no ua haujlwm tawv sai. Txhawm rau kom txo qhov kev ntxhov siab uas tsim los ntawm kev tsim khoom hnyav lossis kev tig, cov khoom yuav tsum tau annealed tag nrho lossis kev ntxhov siab txo qis sai li sai tau tom qab tsim.
Kev Siv Tau:
Siv cov cuab yeej txiav cov chips yog qhov pom zoo vim tias cov chips tuaj yeem ua rau cov hlau tsis xeb ua haujlwm tau sai, cov khoom siv hnyav, cov cuab yeej ntse, thiab kev teeb tsa ruaj khov yuav tsum tau siv. ntawm kev txiav hauv qab cov txheej ua haujlwm uas tau ua haujlwm los ntawm kev dhau los.
