Lub Rockwell Hardness rau 440C stainless hlau pas nrig yog 58. Txij li thaum nws yog Martensitic Stainless hlau nrog cov ntsiab lus siab carbon, nws yog cov khoom siv sib nqus thiab muaj zog nyiam cov hlau nplaum. Nws kuj qhia tau hais tias muaj zog thiab hardness. Charpy Impact Test qhia qhov nqus ntawm 19 joules ntawm lub zog, uas qhia tias muaj zog ntau dua.Lub Charpy Impact Test yog ib qho tseem ceeb heev rau ASTM A276 gr 440C hex bar kom paub lub zog ntawm cov khoom ntawm kev ntxhov siab thiab kev mob hnyav. Hauv qhov kev sim no, lub pendulum loj loj ntaus cov khoom siv. Qhov ntsuas ntawm lub pendulum yuav qhia txog lub zog nqus los ntawm cov khoom hauv Joules.
Lub zog absorbed ntau dua, qhov tsawg dua lub zog ntawm cov khoom. Cov qib stainless hlau feem ntau qhia tau hais tias muaj zog nqus. Txawm li cas los xij, 440C stainless hlau absorbs tsuas yog 20 Joules ntawm lub zog; li no muaj zog dua.
ASTM A479 hom 440C polished bar muaj cov ntsiab lus siab carbon. Yog li ntawd, lawv tau txhim kho lub zog, nce hnav tsis kam, thiab hardness. Cov hauv qab no yog kev siv 440C polished round bar:
Siv tau los ua Riam Blades.
Dav siv tau rau hauv kev tsim cov qauv tsim.
Siv tau rau hauv kev ua ornaments hauv kev lag luam hniav nyiaj hniav kub.
Lub 440C stainless hlau rounds undergo txias-tiav los ua cov txias-dov 440C puag ncig tuav. ASTM A276 hom 440 C yog cov khoom siv tshwj xeeb ntawm cov kab txias txias. Lawv muaj cov ntsiab lus carbon siab thiab koom nrog Martensitic Stainless Steel qeb. Lawv Brinell Hardness yog 285. Lawv siv tau rau hauv kev lag luam, xws li cov hniav nyiaj hniav kub, kev ua zaub mov, tshuaj, roj, thiab roj, thiab lwm yam.
