45Mn2 yog qhov nruab nrab carbon tempered steel, steel phaj lub zog, hnav tsis kam thiab hardenability siab heev. Nyob rau hauv cov roj tseem ceeb quenching txoj kab uas hla ntawm 10 ~ 25mm, nyob rau hauv cov dej tseem ceeb quenching txoj kab uas hla ntawm 22 ~ 45. 45Mn2 tom qab tempering muaj zoo txhua yam khoom, machinability. Nyob rau tib lub sij hawm nyob rau hauv kev kho cua sov nrog overheating rhiab heev thiab tempering brittleness. Them mloog mus rau cov dej quenching yooj yim rau tawg, rhiab rau lub ntsiab lus dawb, weldability thiab txias deformation plasticity yog tsawg thiab lwm yam shortcomings.
45Mn2 steel phaj kub kho:
Thawj quenching cua sov kub (degree): 840; coolant: yog '
Qhov thib ob quenching cua sov kub (degree): -
Tempering kub (degree): 550; coolant: dej, roj
45Mn2 yog ib hom hlau alloy structural steel, nws yog nyob rau hauv high-zoo carbon structural steel nyob rau hauv lub hauv paus ntawm qhov tsim nyog ntxiv ntawm manganese ntsiab thiab ua los ntawm hlau, belongs rau alloy structural steel nyob rau hauv nruab nrab-carbon tempered steel, nrog 45Mn2. yog ua los ntawm cov khoom quenched thiab tempered ntawm kub kub tom qab tempering kev kho mob, koj yuav tau txais nrog zoo heev siab zog thiab zoo toughness, uas yog, muaj ib tug zoo tag nrho txhua yam khoom, feem ntau siv nyob rau hauv lub tsim ntawm dais loj Load bearing shafts, txuas rods. , fasteners thiab lwm yam.
