20Cr precision seamless yeeb nkab yog cov khoom siv high-precision steel yeeb nkab uas tau ua tiav los ntawm kev kos duab txias lossis kub dov. Nws yog siv los thauj cov kua dej, xws li roj, nkev, roj, roj, dej thiab qee yam khoom siv.
20Cr alloy yeeb nkab tom qab kev kho mob carburizing, qhov saum npoo yuav tsim cov koob zoo li tus qauv tempered martensite, lub hardness tuaj yeem ncav cuag 58-62HRC, cov tub ntxhais yuav tsim cov qauv qis-carbon martensite, hardness yog 35-40HRC, lub matrix muaj zog thiab tawv. Tom qab quenching thiab low-temperature tempering, cov hlau no tuaj yeem tau txais cov khoom zoo txhua yam, qhov kub thiab txias cuam tshuam rau qhov toughness, thiab tsis muaj qhov pom tseeb temper brittleness.
