| I-Manganese (Mn) | 1.00 - 2.00% |
| Ikhabhoni (C) | ≤ 0.08% |
| I-Phosphorus (P) | ≤ 0.045% |
| Isibabule (S) | ≤ 0.030% |
| I-nitrogen (N) | 0.10 - 0.30% |
| Insimbi (Fe) | Ibhalansi |
Izinto ezibonakalayo: Izimpawu Ezisemqoka
253MA(UNS S30815) ihlanganisa amandla aphezulu ezinga lokushisa eliphezulu nokumelana ne-oxidation. Lokhu kuyenza ilungele izinhlelo zokusebenza ezisendaweni eyingozi kakhulu, njengeziko kanye nezishintshisi zokushisa. Impahla inokuqukethwe okuphezulu kwe-chromium ne-nickel, okunikeza ukumelana okuhle kakhulu ne-oxidation emazingeni okushisa afika ku-1150°C (2100°F).

Inqubo Yokukhiqiza: Ubuciko bokunemba
Ukwenziwa kwe253MA Amapayipi Ensimbi Engagqwaliilandela amasu okukhiqiza akamuva ukuze kuqinisekiswe ikhwalithi ephezulu nokuqina:
- Ukukhiqiza Amapayipi Angenamthungo: Ikhiqizwe nge-extrusion, ukubhoboza okujikelezayo, nezinqubo zokwelula ukuze kudalwe amapayipi angenamthungo anogqinsi olufana nodonga.
- Inqubo Yokusebenza Okubandayo: Imidwebo ebandayo noma izinqubo zokugqekeza zisetshenziswa ukuze kuzuzwe ubukhulu obunembile nezindawo ezibushelelezi.
- Ukwelashwa Kokushisa: Amapayipi aphathwa ngokushisa emazingeni okushisa athile ukuze athuthukise izakhiwo zawo zemishini kanye nokusebenza kwezinga lokushisa eliphezulu.
