Khoom Description
ASTM 8620 alloy steel yog cov hlau tsis tshua muaj hlau, tseem hu ua SNCM220 steel.Nws muaj lub zog siab, siab tawv thiab hnav tsis kam, thiab feem ntau yog siv los tsim cov khoom siv nrog cov khoom siv siab thiab siab - nrawm nrawm, xws li lub zog, bearings, cycloidal log thiab lwm yam. Tsis tas li ntawd, 8620 alloy steel kuj tseem tuaj yeem txhim kho ntxiv los ntawm kev kho cua sov, xws li quenching thiab tempering, nrog rau normalizing thiab nto quenching.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm 8620 alloy steel suav nrog carbon, silicon, manganese, phosphorus, sulfur, chromium, npib tsib xee thiab molybdenum, thiab qhov sib piv ntawm cov ntsiab lus no ua rau cov khoom muaj cov khoom siv zoo heev thiab lub cev.
