Stainless hlau yog a hlau alloy, ua los ntawm hlau sib xyaw nrog cov khoom xws li chromium, nickel, molybdenum, silicon, aluminium, thiab carbon. Hlau sib xyaw nrog carbon los tsim hlau yog lub ntsiab ntawm stainless hlau . Chromium ntxiv rau ua nws resistant rau xeb.

Raws li, dab tsi ntxiv rau cov hlau ua kom nws nyuaj?

Ntxiv carbon rau hlau los ua steel ua ua kom muaj zog thiab tougher, mus txog rau ib qho point. Ces nws yuav tau muaj zog dua tab sis tsawg tawv (xws li cam khwb cia hlau ). Carbon ntxiv dag zog hlau los ntawm distorting nws crystal latice. Titanium thiab vanadium yuav hardened los ntawm carbon, tab sis tej zaum yuav ua brittle los yog txawm softer los ntawm nws.

Tom qab ntawd, lo lus nug yog, vim li cas peb ntxiv cov ntsiab lus alloying rau hlau? Alloying cov ntsiab lus yog muab tso rau hauv hlau rau ib qho, lossis ntau dua, ntawm cov laj thawj hauv qab no: (1) txhawm rau txhim kho cov khoom siv kho tshuab los ntawm kev tswj cov hardenability thiab tso cai rau qhov kub thiab txias dua thaum tuav lub zog siab thiab ductility; (2) txhawm rau txhim kho cov khoom siv hluav taws xob siab lossis qis qis; (3) rau

Ib yam li ntawd, chromium ntxiv rau hlau li cas?

Manganese (Mn): Manganese yog ntxiv rau hlau txhawm rau txhim kho kev ua haujlwm kub thiab ua kom lub zog, toughness thiab hardenability. Chromium (Cr): Chromium yog ntxiv rau hlau kom muaj zog tiv thaiv oxidation. Qhov kev tiv thaiv no nce ntxiv chromium yog ntxiv.

Dab tsi ntxiv rau cov hlau?

Stainless hlau Alloying Elements

  • Cov pa roj carbon. Carbon thiab hlau yog alloyed ua ke los ua hlau.
  • Manganese. Qhov sib ntxiv ntawm manganese rau hlau txhim kho kev ua haujlwm kub thiab ua kom muaj zog, lub zog, thiab hardenability.
  • Chromium. Chromium yog ua ke nrog hlau los txhim kho nws txoj kev tiv thaiv oxidation.
  • Nickel.
  • Molybdenum.
  • Nitrogen.
  • Tooj.
  • Titanium.
