Ko ngā maitai kore waikura e whakamahia whānuitia ana ko te 304 me te 316, me ētahi atu toronga tae atu ki te 304L, 316L, me te 316H. Hei tāpiri, kei reira te 440C, te 2507, me ētahi atu. Nā, he aha te CF8M me te CF3? Me pēhea e kite tonu ai ahau i te F316? He aha te mea e pā ana ki te TP316L?
1, Hei whakamārama i tēnei, me titiro tuatahi tātou ki te āhua o ngā rauemi. I roto i te umanga takirere me ngā taputapu taputapu, ko ngā rauemi e whakamahia ana ko ngā mea hanga, ngā rakau pae, ngā mea whakarewa, me ngā paipa. He aha ngā paerewa e rite ana mō ēnei āhua rauemi e whā i roto i tā tātou umanga? Tirohia tēnei ripanga:
|
| 304 | 304L | 316 | 316L |
| Te hanga | F304 | F304L | F316 | F316L |
| Pae Stock | 304 | 304L | 316 | 316L |
| Te Maka | CF8 | CF3 | CF8M | CF3M |
| Paipa | TP304 | TP304L | TP316 | TP316L |
Ka tangohia e te rauemi rakau te taumata taketake, ā, ka tāpirihia a F ki te hanga, ko F te hanga; kua tāpirihia a C ki te whakarewanga, ko C te whakarewanga; kua tāpirihia a TP ki te paipa, ko tōna tikanga he paipa.
2、 He aha te rerekētanga i waenga i te 304 me te 316? He aha te L o te 304L me te 316L? He aha te tikanga o te H o te 316H? Me titiro tātou ki te ripanga hanganga matū o ngā momo rerekē o te ASTM A276, ko te 316H te paerewa ASTM A182 (kāore tēnei momo i roto i te paerewa 276):
| Tau | Te Hanganga Matū，% | ||||||||

E ai ki te ripanga, e mārama ana ko te tikanga o te L he iti te ihirangi waro, ko te tikanga o te H he nui te ihirangi waro, ā, ko te rerekētanga i waenga i te 316 me te 304 ko te tāpiri o te huānga Mo, ko te tikanga he huānga Mo tāpiri kei te CF3M ki te whakaritea ki te CF3.
3, Haunga ēnei maitai kowiri tira raupapa-3 noa, he aha atu ngā maitai 2507, 440C me ētahi atu? Ko ēnei maitai kowiri tira upoko-3 noa e kiia ana he maitai kowiri tira austenitic, ko te 2507 he maitai takirua (ferritic me te austenitic), ko te 440C nō te maitai kowiri tira martensitic, ā, kei reira anō ngā maitai kowiri tira ferritic pērā i te 430.
Ka kitea hei whakamārama i ēnei maitai kore waikura noa, ko te tuatahi ko te wehewehe i te āhua: ngā paipa rakau, me ētahi atu, ko te tuarua ko ngā paerewa e whaihia ana, ā, ko te tuatoru ko ngā rerekētanga o te hanganga. Mai i tēnei tirohanga, i muri i te mōhio ki te tikanga o ngā waehere reta, ehara i te mea uaua ki te mārama ki te tikanga o ēnei tohu.
