1. Iron Layer
Layer irin jẹ paati akọkọ ti paipu irin alagbara, ṣiṣe iṣiro fun ju 50% ti gbogbo eto naa. O nipataki pese agbara ati ipata resistance.
2. Chromium Layer
Layer chromium yi Layer irin, nipataki imudara irin alagbara, irin paipu ifoyina ati ipata resistance, idilọwọ ipata dada, discoloration, ati wọ. Awọn paipu irin alagbara ni igbagbogbo ni akoonu chromium ti o kere ju 13% lati ṣe afihan resistance ipata to dara.
3. Nickel Layer
Layer nickel, ti o wa laarin irin ati awọn ipele chromium, mu agbara paipu pọ si ati ductility lakoko ti o daabobo ipele irin lati ifoyina. Awọn paipu irin alagbara pẹlu akoonu nickel ti o kere ju 8% ni a tọka si bi “awọn alloys nickel.”
4. Erogba Layer
Awọn erogba Layer ìgbésẹ bi a ooru dissipator ni alagbara, irin paipu. Išẹ rẹ ni lati dinku olùsọdipúpọ paipu ti imugboroja lakoko ti o npo si lile rẹ ati yiya resistance, ti o jẹ ki o duro diẹ sii.
