Round Steel Product Description
20MnTiB round bar Tshuag steel yog hloov steel rau 20CrMnTi. Nws yog cov qauv hlau alloy uas muaj cov khoom siv zoo thiab cov txheej txheem. Qhov tseem ceeb hardenable txoj kab uas hla hauv cov roj yog 14 ~ 27mm. Nws muaj cov machinability zoo tom qab normalizing thiab qaug zog tiv thaiv tom qab kev kho cua sov. Lub zog, deformation npaum li cas thiab rhiab heev nyob rau hauv khoov load tom qab carburization tsis tsawg tshaj li 20CrMnTi.
Tsis tas li ntawd, 20MnTiB alloy steel muaj qhov me me ntawm cov nplej loj hlob thaum lub sij hawm carburization, yog li nws tuaj yeem txias (tsis qis dua 800 degree) thiab quenched tom qab carburization, tab sis tus nqi deformation thaum kho cua sov yog me ntsis loj dua li ntawm 20CrMnTi. 20MnTiB alloy steel round tuav yog dav siv nyob rau hauv kev tsim cov me me, nruab nrab-load gears thiab lwm yam carburized qhov chaw rau tsheb thiab tsheb laij teb.
