1. Rockwell hardness ntawm 304 stainless hlau
304 stainless hlau yog feem ntau siv austenitic stainless hlau nrog zoo corrosion kuj thiab kev ua tau zoo. Rockwell hardness yog ib txoj hauv kev los ntsuas qhov hardness ntawm cov khoom. Tus nqi hardness ntawm cov khoom yog txiav txim los ntawm kev ntsuas qhov tob indentation. Rockwell hardness ntawm 304 stainless hlau feem ntau yog nruab nrab ntawm HRB70-90, thiab cov nqi tshwj xeeb yog nyob ntawm lub xeev kho cua sov thiab kuaj cov khoom siv. Feem ntau hais lus, lub hardness ntawm 304 stainless hlau yog nruab nrab, uas tuaj yeem ua tau raws li qee qhov kev xav tau ntawm lub zog thiab muaj cov yas zoo, uas yooj yim rau kev ua thiab cov duab.
2. Rockwell hardness ntawm Inconel 625
Inconel 625 yog nickel-based high-temperature alloy paub rau nws zoo heev kub-kub corrosion kuj thiab zoo txhua yam khoom. Piv nrog 304 stainless hlau, Rockwell hardness ntawm Inconel625 feem ntau yog siab dua. Raws li cov ntaub ntawv cuam tshuam, Rockwell hardness ntawm Inconel625 tuaj yeem ncav cuag HRC30-45. Qhov siab tawv no ua rau Inconel625 kom muaj zog zoo thiab hnav tsis kam nyob rau hauv ib puag ncig hnyav xws li qhov kub thiab txias.
3. Yog vim li cas rau qhov sib txawv hardness
Qhov sib txawv ntawm Rockwell hardness ntawm 304 stainless hlau thiab Inconel625 feem ntau yog vim lawv cov khoom muaj pes tsawg leeg thiab microstructure. 304 stainless hlau yog tsim los ntawm hlau, chromium, npib tsib xee thiab lwm yam khoom, thiab nws cov qauv austenite muab nws zoo plasticity thiab toughness. Inconel625 muaj ntau dua npib tsib xee, chromium, molybdenum, niobium thiab lwm yam ntsiab lus, thiab qhov sib ntxiv ntawm cov ntsiab lus no txhawb lub zog thiab hardness ntawm cov hlau. Tsis tas li ntawd, lub microstructure ntawm Inconel625 yog complex, nrog ib tug ntau dua dislocation ceev thiab muaj zog interatomic bonding quab yuam, uas ua rau nws hardness.
