Ile oloke meji alagbara, irin Simẹnti

Ile oloke meji Irin alagbara(DSS) ntokasi si ẹgbẹ kan ti irin alagbara, irin pẹlu metallographic microstructure ti awọn mejeeji ferrite ati austenite kọọkan iṣiro fun nipa 50%. Ni gbogbogbo, akoonu ti awọn ipele ti o kere si nilo lati jẹ o kere ju 30%. Ninu ọran ti akoonu erogba kekere, akoonu Cr jẹ 18% si 28%, ati akoonu Ni jẹ 3% si 10%. Diẹ ninu awọn irin alagbara duplex tun ni awọn eroja alloying gẹgẹbi Mo, Cu, Nb, Ti, ati N. DSS ni awọn abuda ti austenitic ati irin alagbara ferritic. Akawe pẹlu ferrite, o ni o ni ti o ga plasticity ati ductility, ko si yara otutu brittleness, ati significantly dara si intergranular ipata resistance ati alurinmorin išẹ, nigba ti ṣi mimu brittleness, ga gbona iba ina elekitiriki, ati superplasticity bi ferrite alagbara, irin. Akawe pẹluaustenitic alagbara, irin, DSS ni o ni ga agbara ati significantly dara si resistance to intergranular ipata ati kiloraidi wahala ipata. Irin alagbara Duplex ni o ni o tayọ pitting ipata resistance ati ki o jẹ tun nickel-fifipamọ awọn alagbara, irin. Awọn ipele ti o wa ti simẹnti irin alagbara duplex nipasẹ sisọnu idoko-owo epo-eti ti o padanu: 1.4460, 1.4462, 1.4468, 1.4469, 1.4517, 1.4770, A 890 1C, A 890 1A, A 890 3A, 5A, A 890 995 1B, A 995 4A, A 995 5A, 2205, 2507, 022Cr22Ni5Mo3N, 022Cr25Ni6Mo2N
