Duplex igwe anaghị agba nchara 2205 Nkedo

2205 duplex igwe anaghị agba nchara bụ duplex igwe anaghị agba nchara mejupụtara 21% chromium, 2.5% molybdenum na 4.5% nickel-nitrogen alloy. Ihe owuwu ferrite na austenite nke ọ bụla ruru ihe dịka 50%. Ọ nwere ike dị elu, mmetụta siri ike dị mma yana mma n'ozuzu ya na nguzogide corrosion nrụgide mpaghara. Ike mkpụrụ nke 2205 duplex igwe anaghị agba nchara bụ okpukpu abụọ nkeaustenitic igwe anaghị agba nchara. Njirimara a na-enyere ndị na-emepụta aka belata ibu mgbe ha na-emepụta ngwaahịa, na-eme ka alloy a dịkwuo ọnụ karịa 316 na 317L. Alloy a dabara adaba maka oke okpomọkụ nke -50°F/+600°F. Maka ngwa gafere oke okpomọkụ a, a nwekwara ike ịtụle alloy a, mana enwere oke ụfọdụ, ọkachasị mgbe etinyere ya n'ụdị welded.

Nguzogide corrosion na Jiri gburugburu:
Tụnyere 316L na 317L austenitic igwe anaghị agba nchara, 2205 duplex igwe anaghị agba nchara nwere elu arụmọrụ na iguzogide pitting corrosion na crevice corrosion. Ọ nwere nnukwu nguzogide corrosion. E jiri ya tụnyere austenitic, ọnụọgụ ọnụọgụ nke mgbasawanye thermal dị ala na conductivity thermal dị elu. E jiri ya tụnyere austenitic igwe anaghị agba nchara, duplex igwe anaghị agba nchara 2205 alloy nwere ugboro abụọ mkpakọ ike. E jiri ya tụnyere 316L na 317L, onye nrụpụta nwere ike belata ibu ya. Alloy 2205 dabara adaba maka oke okpomọkụ nke -50°F/+600°F. N'okpuru mmachi siri ike (karịsịa maka ụlọ welded), enwere ike iji ya na obere okpomọkụ.
