EN 1.4460/AISI 329/F52/SUS329J1/UNS S32900 Insimbi Engagqwali

I-EN 1.4460/AISI 329/F52/UNS S32900 iyinsimbi engagqwali eyi-duplex (austenitic-ferritic) ebonakala ngokumelana ne-stress corrosion cracking (SCC), ukumelana okuphezulu nokugoba, ukubola, nokugqwala okuvamile, namandla emishini aphezulu kakhulu. Ingasetshenziswa ezinhlelweni zasolwandle zamasilinda amanzi noma kuphi lapho kudingeka ukumelana nokugqwala okuhle. Inikeza ukumelana okuhle kakhulu nokugqwala, ikakhulukazi endaweni ene-chloride. Futhi kunikeza ukumelana okwengeziwe ekugqwaleni kwengcindezi, ukugqwala komgodi, nokugqwala kokukhathala.

Ukwakhiwa kwamakhemikhali

Ithebula elilandelayo libonisa ukwakheka kwamakhemikhali ensimbi engagqwali yebanga lama-329:

a) I-Rp0.2 ne-Rp1.0 zihambisana no-0.2% we-offset kanye no-1.0% wamandla esivuno se-offset, ngokulandelanayo.
b) Isekelwe ku-L0 = 5.65 √S0 lapho u-L0 eyigeji yobude bokuqala kanye no-S0 indawo yokuqala ye-cross-section.

c) Isidingo ngokuya nge-ASTM A790
d) Imfuneko ngokuya nge-EN 10297-2
