US 309/ 309S (UNS S30900/ S30908) ígwè

TYPES 309 NA 309S  bụ austenitic chromium-nickel igwe anaghị agba nchara na-enye ezigbo nguzogide corrosion na nguzogide okpomọkụ gbakwunyere ezigbo ike n'ime ụlọ yana oke okpomọkụ. Ụdị 309S  bụ otu ụdị 309 ewezuga ọdịnaya carbon dị ala nke na-ebelata mmiri ozuzo carbide ma na-emezi weldability.

Alloy 309 na 309S kacha mara amara maka ọrụ okpomọkụ dị elu. Alloy a na-arụ ọrụ nke ọma ruo 2000 Celsius F, ọkachasị ma ọ bụrụ na achọrọ nguzogide oxidation. Igwe anaghị agba nchara 309 na 310 bụ ndị na-eme ihe ngosi dị elu n'etiti akara igwe anaghị agba nchara dị na ngwaahịa anyị. Ọdịnaya nickel na chromium dị elu yana nhazi ọka na-enweghị isi na-ebute:

• Emelitere nguzogide cyclic oxidation
• Mmụba nguzogide sulfidation
• Ka mma elu okpomọkụ ike
• Emelitere nguzogide corrosion intergranular

309S (UNS S30908) igwe anaghị agba nchara bụ ụdị carbon dị ala nke alloy. A na-eji ya maka ịdị mfe imepụta ihe.

309H (UNS S30909) bụ mgbanwe carbon dị elu nke emepụtara maka nkwụsi ike na-akpụ akpụ. Ọtụtụ mgbe nha ọka na carbon ọdịnaya nke efere nwere ike izute ma 309S na 309H chọrọ. Mgbe a na-ekpo ọkụ n'etiti 1202 - 1742 ° F (650 - 950 ° C) alloy na-adabere na mmiri ozuzo nke sigma. Ngwọta na-ekpochapụ ọgwụgwọ na 2012 - 2102°F (1100 - 1150°C) ga-eweghachi ogo nke ike. Enwere ike ịgbanye ma hazie Alloy 309 n'ụzọ dị mfe site na usoro nrụpụta ụlọ ahịa ọkọlọtọ.
