410S tšepe e sa hloekang ke eng?
410S tšepe e sa hloekangke phetoho e tlaase ea carbon, e sa thatafatseng ea martensitic stainless steel 410. E na le hoo e ka bang 11.5-13.5% chromium le lintho tse ling tse nyenyane tse kang manganese, phosphorus, sebabole, silicon, 'me ka linako tse ling nickel. Likahare tse tlase tsa carbon tsa 410S li ntlafatsa ho cheseha ha eona le ho fokotsa kotsi ea ho thatafala kapa ho petsoha nakong ea ho cheselletsa. Leha ho le joalo, sena se boetse se bolela hore 410S e na le matla a tlaase ha e bapisoa le maemo a 410. E fana ka khanyetso e ntle ea kutu, haholo-holo libakeng tse bonolo, empa ha e hanyetsane ho feta litšepe tse sa hloekang tsa austenitic tse kang 304 kapa 316.

| 3Cr12 | 460 | 220 | 18% |
| 3Cr12L | 455 | 223 | 20% |
| 410S | 415 | 183 | 20% |
Ⅲ.3Cr12 le 410S Libaka tsa Kopo ea Letlapa la Tšepe
3Cr12: E sebelisoa haholo lisebelisoa tsa lik'hemik'hale, lisebelisoa tsa ho lokisa lijo, le thepa ea kaho.Ho hanyetsa ha eona hantle ho etsa hore e be sebaka se loketseng bakeng sa tikoloho e mongobo le e nang le asiti.
410S:Hangata e sebelisoa likarolong tsa turbine, li-boilers, le li-heaters tsa mocheso libakeng tse phahameng tsa mocheso. E loketse lisebelisoa tse hlokang mocheso le ho roala ho hanyetsa.
Ⅳ.Kakaretso ea Papiso
Lintlha tsa bohlokoa tsa 3Cr12:
• Sebopeho: Likahare tsa Chromium tsa 11.0–12.0%, carbon content ≤ 0.03%.
• Corrosion Resistance: E loketse tikoloho e senyang hanyenyane, joalo ka likarolo tsa sebopeho, lisebelisoa tsa merafo, le lisebelisoa tse akaretsang tsa indasteri.
• Weldability: Ts'ebetso e ntle ea welding ka lebaka la khabone ea eona e tlase.
| Standard | Kereiti |
| Maemo a Afrika Boroa | 3Cr12 |
| Tekanyetso ea Europe | 1.4003 |
| US Standard | UNS S41003 (410S) |
| Maemo a Machaba | X2CrNi12 |
• 410S: Ho thatafala ho hoholo empa ho thata ho tlase hanyane, ha e na titanium, e na le matla a lekaneng a ho chesehela, 'me e loketse lits'ebetso tsa kakaretso tse thibelang kutu.
• 3Cr12: Khabone e tlase, e theko e tlase, e loketse tikoloho e senyang hanyenyane, e nang le cheseletso e ntle.
