Isọri ti Irin Alagbara

Irin alagbara, irin le ti pin si austenitic alagbara, irin, ferritic alagbara, irin, martensitic alagbara, irin ati duplex alagbara, irin ni ibamu si awọn oniwe-metallographic be.

(1) Austenitic alagbara, irin

Eto iwọn otutu yara ti irin alagbara austenitic jẹ austenite, eyiti o ṣẹda nipasẹ fifi nickel ti o yẹ si irin alagbara chromium giga.

Irin alagbara Austenitic ni eto austenite iduroṣinṣin nikan nigbati Cr ni nipa 18%, Ni 8% si 25%, ati C nipa 0.1%. Austenitic alagbara, irin da lori Cr18Ni9 irin-orisun alloy. Pẹlu awọn lilo oriṣiriṣi, jara mẹfa ti awọn irin alagbara austenitic ti ni idagbasoke.

Awọn ipele ti o wọpọ ti irin alagbara austenitic:

Irin alagbara Austenitic ni iye nla ti Ni ati Cr, ṣiṣe austenite irin ni iwọn otutu yara. O ni ṣiṣu to dara, toughness, weldability, resistance corrosion ati ti kii ṣe oofa tabi awọn ohun-ini oofa alailagbara. O ni o ni ti o dara ipata resistance ni oxidizing ati atehinwa media. O ti wa ni lo lati ṣe acid-sooro itanna, gẹgẹ bi awọn ipata-sooro awọn apoti ati ohun elo ikan ati gbigbe. Awọn paipu, nitric acid-sooro awọn ẹya ẹrọ, ati bẹbẹ lọ, tun le ṣee lo bi ohun elo akọkọ ti awọn ohun ọṣọ. Irin alagbara Austenitic ni gbogbogbo gba itọju ojutu, iyẹn ni, irin naa jẹ kikan si 1050 si 1150 ° C, ati lẹhinna tutu-omi tabi tutu-afẹfẹ lati gba eto austenite kan-akoko kan.

(2) ferritic alagbara, irin

Awọn ipele ti o wọpọ ti irin alagbara irin ferritic: (1) 1Cr17; (2) 00Cr30Mo2; (3) 00Cr17; (4) 00Cr17; (5) 1Cr17Mo; (6) 00Cr27Mo;

Irin alagbara Ferritic jẹ irin alagbara, irin eyiti eto rẹ jẹ ferrite ni iwọn otutu yara. Chromium akoonu jẹ 11% -30%, awọn oniwe-ipata resistance, toughness ati weldability ilosoke pẹlu awọn ilosoke ti chromium akoonu, kiloraidi wahala ipata resistance ni o dara ju miiran orisi ti irin alagbara, irin yi ni gbogbo igba ko ni nickel, ma O tun ni kekere kan iye ti Mo, Ti, Nb ati awọn miiran eroja. Iru irin yii ni awọn abuda ti iṣe adaṣe igbona nla, olusọdipúpọ imugboroja kekere, resistance ifoyina ti o dara, ati resistance ipata aapọn to dara julọ. O ti wa ni okeene lo lati gbe awọn oju aye resistance, omi oru, omi ati oxidizing acids. Awọn ẹya ti o bajẹ. Bibẹẹkọ, awọn ohun-ini ẹrọ ati iṣẹ ṣiṣe ilana ko dara, ati pe wọn lo pupọ julọ ni awọn ẹya ti o ni sooro acid pẹlu aapọn kekere ati bi awọn irin anti-oxidation. O tun le gbe awọn ẹya ti o ṣiṣẹ ni awọn iwọn otutu giga, gẹgẹbi awọn ẹya tobaini gaasi.
