17-4PH igwe anaghị agba nchara

Alloy 17-4 bụ chromium-ọla kọpa mmiri ozuzo siri ike igwe anaghị agba nchara nke a na-eji maka ngwa chọrọ ike dị elu na ọkwa dị oke ala nke nguzogide corrosion. Ọ bụ otu n'ime akara ule mmiri ozuzo a na-ejikarị eme ihe, n'ihi na ọ nwere ike siri ike ruo ihe dịka 572 ° F ebe ọ na-egosipụta ezigbo nguzogide corrosion na ọnọdụ okpomọkụ niile. Alloy 17-4 nwere nguzogide zuru oke na corrosion ikuku ma ọ bụ na nnu acid diluted ebe nguzogide corrosion ya na Alloy 304 ma ọ bụ 430. Alloy 17-4 nwere ike ịgwọ okpomọkụ dị iche iche iji mepụta ọtụtụ ihe onwunwe. Enwere ike imeziwanye ihe eji arụ ọrụ ya site na ọgwụgwọ okpomọkụ ebe enwere ike nweta ike mkpụrụ dị elu ruo 180 ksi. Agaghị eji alloy 17-4 mee ihe na okpomọkụ karịrị 572°F ma ọ bụ na oke okpomọkụ.
