| IManganese (Mn) | 1.00 - 2.00% |
| Ikhabhoni (C) | ≤ 0.08% |
| Phosphorus (P) | ≤ 0.045% |
| Isulfure (S) | ≤ 0.030% |
| I-nitrogen (N) | 0.10 - 0.30% |
| Intsimbi (Fe) | Ibhalansi |
Iimpawu zezinto eziphathekayo: Iimpawu eziphambili
253MA(UNS S30815) idibanisa amandla aphezulu obushushu obuphezulu kunye nokumelana ne-oxidation. Oku kuyenza ilungele ukusetyenziswa kwiindawo ezingqongileyo ezigqithisileyo, ezifana neziko kunye nokutshintsha ubushushu. Izinto eziphathekayo zinomxholo ophezulu we-chromium kunye ne-nickel, enikezela ukuchasana okugqwesileyo kwi-oxidation kumaqondo okushisa ukuya kwi-1150 ° C (2100 ° F).

Inkqubo yeMveliso: Ubuchule bokuCwangcisa
Ukwenziwa kwe253MA imibhobho yentsimbi engatyiwayoilandela iindlela zamva nje zemveliso zokuqinisekisa umgangatho ophezulu kunye nokuqina:
- Ukwenziwa kweMibhobho engenamthungo: Iveliswe nge-extrusion, ukugqobhoza okujikelezayo, kunye neenkqubo zokwandisa ukwenza imibhobho engenamthungo enobunzima obufanayo bodonga.
- Inkqubo yokuSebenza okubandayo: Umzobo obandayo okanye iinkqubo zokuthutha zisetyenziselwa ukufikelela kwimilinganiselo echanekileyo kunye neendawo ezigudileyo.
- Unyango lobushushu: Imibhobho ifumana unyango lobushushu kumaqondo athile obushushu ukunyusa iipropathi zabo zoomatshini kunye nokusebenza kobushushu obuphezulu.
