Kev piav qhia txog kev hnav-resistant steel daim hlau

Cov tshuaj muaj pes tsawg leeg ntawm cov khoom zoo heev hnav-resistant alloy hnav-resistant txheej yog siab li 4-5% cov ntsiab lus carbon thiab 25-30% chromium cov ntsiab lus. Qhov ntim feem ntawm Cr7C3 carbide nyob rau hauv nws cov qauv metallographic nce mus txog 50%, nrog rau macroscopic hardness ntawm HRC56-62 thiab hardness ntawm HV1400-1800 rau chromium carbide. Vim tias txoj kab ncaj nraim ntawm carbides nyob rau hauv cov kev coj coj, txawm tias piv rau cam khwb cia alloys nrog tib yam muaj pes tsawg leeg thiab hardness, hnav tsis kam yog ntau tshaj ob npaug.
