Abantu abaninzi kulula ukudibanisa umbhobho we-316 wensimbi engenasici kunye ne-316L umbhobho wensimbi engenasici, becinga ukuba luhlobo olufanayo lombhobho wensimbi, kodwa ngokwenene akunjalo.
Umahluko othile phakathi kwe-316 kunye ne-316L yeentsimbi ezingenasici zimi ngolu hlobo lulandelayo:
1. Ukuqulunqwa kweekhemikhali
Umxholo wekhabhoni we-316L wensimbi engenasici ungaphantsi kune-316 yensimbi engenasici.Kunokuthiwa "316L" yintsimbi ye-ultra-low carbon 316.I-316L yensimbi engenasici inomxholo ophezulu we-molybdenum kune-316.
2. Ukumelana nokubola
I-316L yensimbi engenasici inokumelana ne-corrosion engcono.
3. Amandla
I-316 ineempawu ezinamandla zoomatshini.Amandla obunzima bombhobho we-316 wensimbi engenasici uphezulu kunombhobho we-316L wensimbi engenasici.Amandla e-tensile ye-316 yensimbi engenasici kufuneka ibe mkhulu kune-520MPa, ngelixa i-316L yensimbi engenasici ifuneka kuphela ukuba ibe mkhulu kune-480MPa.Oku kungenxa yokuba i-carbon (C) yinto enamandla yokwenza i-austenitic, enokuphucula kakhulu amandla entsimbi.
4. Ukumelana nokushisa okuphezulu
I-316L insimbi engenasici ingasetyenziselwa ngokuqhubekayo kwiqondo lokushisa eliphezulu, ngelixa i-316 ayikwazi.Kuluhlu lwe-800 ~ 1575 degrees, kungcono ukuba ungaqhubeki ngokuqhubekayo kwi-316 yensimbi engenasici.Ukuxhatshazwa kwe-carbide precipitation ye-316L yensimbi engenasici ingcono kune-316 yensimbi engenasici, kwaye inokusetyenziswa ngokuqhubekayo kwi-800 ~ 1575 degrees.
5. Ukuwelda
I-316 insimbi engenasici ine-weldability efanelekileyo, enokuthi ifakwe ngeendlela eziqhelekileyo ze-welding standard.Icandelo le-welding ye-316 yensimbi engenasici idinga i-post welding annealing ukuphucula ukuxhathisa ukubola.Nangona kunjalo, ukuba i-316L yensimbi engenasici isetyenzisiweyo, i-post weld annealing ayifuni.
