Uyini umehluko phakathi kuka-304 no-316 insimbi engagqwali?

 

Umehluko oyinhloko phakathi kwe-304 ne-316 yensimbi engagqwali eyenza ihluke ukungezwa kwe-molybdenum. Le alloy ithuthukisa kakhulu ukumelana nokugqwala, ikakhulukazi ezindaweni ezinosawoti omningi noma ezichayeke nge-chloride. I-316 insimbi engagqwali iqukethe i-molybdenum, kodwa i-304 ayinayo.

I-304 kanye ne-316 insimbi engagqwali yizinhlobo ezimbili ezivame kakhulu neziguquguqukayo zensimbi engagqwali. Nakuba babelana ngokufana okuningi,
kunomehluko oyinhloko ekubunjweni kwazo, ukumelana nokugqwala, kanye nezicelo.

1. Ukwakhiwa Kwekhemikhali:

• 304 Insimbi Engagqwali:
  • I-Chromium:18-20%
  • I-Nickel:8-10.5%
  • I-Manganese:≤2%
  • Ikhabhoni:≤0.08%
• 316 Insimbi Engagqwali:
  • I-Chromium:16-18%
  • I-Nickel:10-14%
  • I-Molybdenum:2-3%
  • I-Manganese:≤2%
  • Ikhabhoni:≤0.08%

Umehluko Obalulekile:I-316 insimbi engagqwali iqukethe i-2-3% ye-molybdenum, engekho ku-304. Lokhu kuhlanganisa kuthuthukisa ukumelana nokugqwala, ikakhulukazi ngokumelene nama-chloride nezinye izihlungi zezimboni.

2.Ukumelana Nokugqwala:

• 304 Insimbi Engagqwali:
  • Inikeza ukumelana nokugqwala okuhle ezindaweni eziningi, ikakhulukazi emanzini angenawo i-chlorine.
• 316 Insimbi Engagqwali:
  • Ukumelana nokugqwala okuphezulu uma kuqhathaniswa no-304, ikakhulukazi ezindaweni ezinokhahlo ezichayeka emanzini anosawoti, ama-chloride, nama-asidi.

Umehluko Obalulekile:I-316 insimbi engagqwali imelana kakhulu nokugqwala, iyenza ilungele ulwandle, amakhemikhali, nezinye izindawo ezinokhahlo.

3. Izici zikaMechanical:

• 304 Insimbi Engagqwali:
  • Amandla Okuqina: ~505 MPa (73 ksi)
  • Amandla Okukhiqiza: ~215 MPa (31 ksi)
• 316 Insimbi Engagqwali:
  • Amandla Okuqina: ~515 MPa (75 ksi)
  • Amandla Okukhiqiza: ~290 MPa (42 ksi)

Umehluko Obalulekile:I-316 inokuqina okuphezulu kancane namandla esivuno, kodwa umehluko mncane.

4. Izicelo:

• 304 Insimbi Engagqwali:
  • Okuvame ukusetshenziswa emishinini yasekhishini, izinto zasendlini, izinsimbi zezimoto, izinhlelo zokusebenza zezakhiwo, neziqukathi zezimboni.
• 316 Insimbi Engagqwali:
  • Okuncanyelwayo ezindaweni ezidinga ukumelana nokugqwala okuthuthukisiwe, okufana nempahla yasolwandle, okokusebenza kwamakhemikhali, okokwenza imithi kanye nemishini yezokwelapha, kanye nezindawo ezinosawoti omningi.

Umehluko Obalulekile:316 isetshenziswa lapho ukumelana nokugqwala okuphakeme kuyadingeka, ikakhulukazi ezindaweni ezinokhahlo.

5. Izindleko:

• 304 Insimbi Engagqwali:
  • Ngokuvamile kubiza kancane ngenxa yokungabikho kwe-molybdenum.
• 316 Insimbi Engagqwali:
  • Ibiza kakhulu ngenxa yokwengezwa kwe-molybdenum, ethuthukisa ukumelana nokugqwala kodwa yandisa izindleko zempahla.

Isifinyezo:

• 304 Insimbi Engagqwaliiyinsimbi engagqwali enenhloso yonke enokumelana nokugqwala okuhle, evame ukusetshenziswa ezindaweni lapho ubungozi bokugqwala buphansi.
• 316 Insimbi Engagqwaliinikeza ukumelana nokugqwala okungcono, ikakhulukazi ngokumelene nama-chloride nezinye izinto ezonakalisayo, okuyenza ilungele izindawo ezidinga kakhulu.

Ukukhetha phakathi kwalokhu okubili kuvame ukuncika ezimeni ezithile zemvelo kanye nezinga elidingekayo lokumelana nokugqwala.
