Duplex Steel
Duplex igwe anaghị agba nchara (DSS) na-ezo aka ihe dị ka 50% nke ọ bụla nke ígwè ahụ na Austenitic, na ọdịnaya nke obere oge bụ opekata mpe 30% nke igwe anaghị agba nchara. N'ihe banyere C dị ala, ọdịnaya CR bụ 18% ruo 28%, yana ọdịnaya Ni bụ 3% ruo 10%. Ụfọdụ ígwè nwekwara ihe alloy dị ka MO, CU, NB, Ti, N na ihe ndị ọzọ alloy. Ụdị ígwè a nwere àgwà nke Austenitic na ferrite igwe anaghị agba nchara. E jiri ya tụnyere ferrite, plasticity na ike siri ike dị elu, ọ dịghị ụlọ okpomọkụ na-agbaji, na nguzogide corrosion na ịgbado ọkụ nke nguzogide kristal na-akawanye mma. The 475 ℃ brittleness na kpo oku ọnụọgụ nke 475 Celsius C na ígwè igwe anaghị agba nchara nwere àgwà nke super plasticity. E jiri ya tụnyere igwe anaghị agba nchara austenitic, ike dị elu na kristal corrosion na chloride stress corrosion abawanyela nke ukwuu. Igwe anaghị agba nchara okpukpu abụọ nwere ezigbo nguzogide pore, ọ bụkwa ụdị nickel na-echekwa nickel igwe anaghị agba nchara.
