Stainless Steel 316 (US standard ASTM S31600, Chinese standard 06Cr17Ni12Mo2) ke molybdenum e nang le austenitic steel stainless, eo hangata e bitsoang "marine-grade stainless steel" ka lebaka la ho hanyetsa ha eona ho matla ha kutu. E thehiloe holim'a tšepe e sa hloekang ea 304 ka ho eketsoa ha 2-3% molybdenum (Mo), e leng ho matlafatsang ho hanyetsa ha eona ho pitting le crevice corrosion.
Ⅰ.Litšobotsi tsa Bohlokoa
1.Exceptional Corrosion Resistance: Ho eketsoa ha molybdenum ho fana ka ts'ebetso e phahameng ka ho fetisisa tikolohong ea chloride (mohlala, metsi a leoatle, spray ea letsoai), e nang le khanyetso ea likoti e fetang hole ea tšepe e sa hloekang ea 304. Sekhahla sa kutu ea eona ho 10% ea sulfuric acid e ka ba ka tlase ho 0.1 mm / selemo.
2.Ts'ebetso ea Mocheso o Phahameng: Matla a phahameng a mocheso le khanyetso ea oxidation, ka mocheso oa ts'ebeletso o tsoelang pele ho fihla ho 870 ° C le ts'ebeletso ea nakoana e fihlang ho 925 ° C.
3.Mechanical Properties: Ho hlahisa matla ≥205 MPa, matla a tensile ≥515 MPa, elongation ≥40%, ho fana ka matla a matle le bokhoni ba ho thatafatsa mosebetsi.
4.Motlakase oa Magnetism: E seng ea makenete sebakeng sa tharollo-annealed; e ka fetoha makenete hanyane kamora ho sebetsa ha serame. E loketse lisebelisoa tse utloang matla a khoheli.
Ⅱ.Sebopeho sa Lik'hemik'hale (Matšoao a Bohlokoa)
| Element | Mefuta e fapaneng ea litaba | Mosebetsi |
| Khabone (C) | ≤0.08% | E laola ho bola ha intergranular |
| Chromium (Cr) | 16.0-18.0% | E etsa filimi e sa sebetseng, e thibela mafome |
| Nickel (Ni) | 10.0-14.0% | E tsitsisa sebopeho sa austenitic, ho hanyetsa acid |
| Molybdenum (Mo) | 2.0-3.0%. | Core element, e fana ka khanyetso ea pitting |
| Manganese (Mn) | ≤2.00% | Deoxidizer |
| Silicon (Si) | ≤0.75% | Deoxidizer |
Ⅲ.Thepa e Tloaelehileng ea Mechini
Thepa ea Motjhini oa Thempereichara ea Kamore (Naha ea Tharollo-Annealed)
Ena ke boemo bo atileng haholo bakeng sa tšepe e sa hloekang ea 316, e fanang ka tekano e ntle ea thepa.
| Thepa | Boleng bo Tlwaelehileng | Tlhokahalo e Tloaelehileng (ASTM A240) |
| Tensile Strength (Rm) | 515 - 620 MPa | ≥ 515 MPa |
| Matla a Kotulo (Rp0.2) | 205 - 310 MPa | ≥ 205 MPa |
| Elongation (A) | 40% - 50% | ≥ 40% |
| Ho thatafala (HBW) | 149 - 217 | ≤217 |
| Elastic Modulus (E) | 193 GPA | - |
Lintlha:
1.Matla a itekanetseng: Ho fana ka matla ho pota 200-300 MPa, ho etsa hore ho be bonolo ho theha le ho sebetsa.
2.Polasetiki e ntle haholo: Elongation e atisa ho feta 40%, e bontšang ho tiea ho hoholo le ho hanyetsa ho robeha ha brittle.
3.Ho sebetsa ka thata: Matla le boima li eketseha haholo nakong ea ho sebetsa ha serame (mohlala, ho roala ho batang, ho taka), empa polasetiki e fokotseha.
Ⅳ.Mabaka a Kopo a mantlha
1.Boenjiniere ba Marine: Lisebelisoa tsa likepe, li-platform tsa offshore, lisebelisoa tsa ho tlosa letsoai.
2.Chemical & Energy Industries: Li-reactors, liphaephe, lisebelisoa tsa mocheso (tse hanyetsanang le li-acids/alkalis).
3.Medical & Food Industries: Lisebelisoa tsa ho buoa, lisebelisoa tsa meriana, mechine ea ho lokisa lijo (e kopana le litekanyetso tsa bohloeki).
4.Architecture & Mokhabiso: Ho haha marako a likharetene, litšepe libakeng tse lebōpong la leoatle (tse hanyetsanang le ho bola ha letsoai).
Ⅴ.Tloaelehileng Derived Kereiti
316L: Phetolelo e tlaase ea carbon (C≤0.03%), ho cheseha ho molemo le ho hanyetsa ho senyeha ha intergranular, ho loketse bakeng sa likarolo tse boima tsa welded.
316H: Phetolelo ea carbon e phahameng, matla a phahameng a mocheso o phahameng, a loketse mehaho e nang le khatello e phahameng ea mocheso.
