I-Stainless Steel 316 (i-ASTM S31600 eqhelekileyo yase-US, i-standard yaseTshayina 06Cr17Ni12Mo2) yi-molybdenum equkethe i-austenitic steel stainless, edla ngokubizwa ngokuba yi "marine-grade stainless steel" ngenxa yokumelana nokugqwala kwayo. Isekelwe kwi-304 yensimbi engenasici kunye nokongezwa kwe-2-3% ye-molybdenum (Mo), eyandisa kakhulu ukuchasana kwayo kwi-pitting kunye ne-crevice corrosion.
Ⅰ.IiMpawu eziPhambili
1.I-Resistance ye-Corrosion ekhethekileyo: Ukongezwa kwe-molybdenum kunika ukusebenza okuphezulu kwiindawo ze-chloride (umzekelo, amanzi olwandle, isitshizi setyuwa), kunye nokuchasana kwe-pitting okungaphezulu kakhulu kwe-304 yensimbi engenasici. Izinga lokubola kwayo kwi-10% ye-asidi ye-sulfuric ingaba ngaphantsi kwe-0.1 mm / ngonyaka.
2.Ubushushu obuphezulu bokuSebenza: Amandla aphezulu obushushu obuphezulu kunye nokumelana ne-oxidation, kunye nenkonzo eqhubekayo yokushisa ukuya kuma-870 ° C kunye nenkonzo yekhefu ukuya kwi-925 ° C.
3.IiPropati zoomatshini: Amandla esivuno ≥205 MPa, amandla okuqina ≥515 MPa, elongation ≥40%, enikezela ngokuqina okuhle kunye nobuchule bokwenza lukhuni.
4.I-Magnetism ephantsi: I-non-magnetic kwimeko yesisombululo-i-annealed; inokuba yimagnethi kancinane emva kokusebenza okubandayo. Ifanelekile kwisixhobo esinobuntununtunu kwimihlaba yemagnethi.
Ⅱ.Ukubunjwa kwemichiza (Izalathi ezingundoqo)
| Isiqalelo | Uluhlu lomxholo | Umsebenzi |
| Ikhabhoni (C) | ≤0.08% | Ilawula umhlwa phakathi kwegranular |
| I-Chromium (Cr) | 16.0-18.0% | Yenza ifilimu ye-passive, ikhusela umhlwa |
| I-Nickel (Ni) | 10.0-14.0% | Uzinzisa isakhiwo se-austenitic, ukuxhathisa kwe-asidi |
| Molybdenum (Mo) | 2.0-3.0%. | I-core element, inika ukuchasana kwe-pitting |
| IManganese (Mn) | ≤2.00% | I-Deoxidizer |
| Isilicon (Si) | ≤0.75% | I-Deoxidizer |
Ⅲ.Iipropati zoomatshini eziqhelekileyo
IiPropati zoomatshini boBubushushu beGumbi (IsiSombululo-eSinyanzeliso seSimo)
Eli lelona lizwe liqhelekileyo kwi-316 yensimbi engenasici, enika ibhalansi efanelekileyo yeepropati.
| Ipropati | Ixabiso eliqhelekileyo | imfuneko esemgangathweni (ASTM A240) |
| Amandla okuqina (Rm) | 515 - 620 MPa | ≥ 515 MPa |
| Amandla eSivuno (Rp0.2) | 205 - 310 MPa | ≥ 205 MPa |
| Ubude (A) | 40% - 50% | ≥ 40% |
| Ukuqina (HBW) | 149 - 217 | ≤ 217 |
| Imodyuli yeelastiki (E) | 193 GPA | - |
Amanqaku:
1.Amandla aphakathi: Amandla okuvelisa malunga ne-200-300 MPa, okwenza kube lula ukwenza kunye nokusebenza.
2.Iplastikhi egqwesileyo: Ubude buqheleke ngaphezu kwe-40%, ebonisa ukuqina okuphezulu kunye nokumelana nokwaphuka kwe-brittle.
3. Ukusebenza nzima: Amandla kunye nobunzima banda kakhulu ngexesha lokusebenza okubandayo (umzekelo, ukugoqa okubandayo, ukudweba), kodwa iplastiki iyancipha.
Ⅳ.IiNdawo zeSicelo eziPhambili
1.Ubunjineli baseLwandle: Ukufakelwa kweenqanawa, amaqonga angaphesheya, izixhobo zokukhupha ityuwa.
2.Amashishini eChemical & Energy: Iireactors, imibhobho, izitshintshi zobushushu (zixhathisa kwiiasidi/alkali).
3.Medical & Food Industries: Izixhobo zotyando, izixhobo zamachiza, oomatshini bokulungisa ukutya (uhlangabezana nemigangatho yococeko).
4.Uyilo kunye nokuhombisa: Ukwakha iindonga zamakhethini, iintsimbi kwiindawo eziselunxwemeni (ukumelana nokonakala kwesitshizi setyuwa).
Ⅴ.Amabanga afunyenweyo aqhelekileyo
316L: I-low-carbon version (C≤0.03%), i-weldability engcono kunye ne-intergranular resistant corrosion, ifanelekile kumacandelo adibeneyo adibeneyo.
316H: Inguqu yekhabhoni ephezulu, amandla aphezulu aphezulu, afanelekile kwizakhiwo ezinoxinzelelo oluphezulu.
