20MnCr5 (1.7147) muaj qhov sib npaug zoo ntawm lub zog thiab tawv thiab tsim nyog rau nruab nrab load thiab nruab nrab cov ntawv thov kev ntxhov siab. 20MnCr5 tuaj yeem txhim kho nws cov khoom siv kho tshuab, tshwj xeeb tshaj yog hardness thiab lub zog, los ntawm kev kho cua sov (quenching thiab tempering). Vim qhov sib ntxiv ntawm cov ntsiab lus alloy thiab kev kho cua sov zoo dua, 20MnCr5 muaj kev hnav zoo dua.
siv:
Gears thiab Bearings: 20MnCr5 yog siv rau hauv iav thiab bearings manufacturing. Nws lub zog siab thiab hnav tsis kam ua rau nws haum rau cov iav tshuab uas raug rau siab torque thiab kev kub ceev, xws li tsheb kis tau tus mob, kev lag luam machinery kis, thiab lwm yam.
Cov khoom siv tshuab: Txij li 20MnCr5 muaj qhov sib npaug zoo ntawm lub zog thiab tawv, nws feem ntau siv los tsim ntau yam khoom siv, xws li shafts, pins, chains, thiab lwm yam.
Billet processing: 20MnCr5 tuaj yeem siv los ua cov khoom siv los yog cov khoom siv rau cov khoom siv welded vim nws yooj yim ntawm kev ua thiab txhim kho txhua yam khoom tom qab kev kho cua sov.
20MnCr5 txoj kev kho cua sov muaj xws li quenching thiab tempering.
1. Quenching: Cov khoom siv 20MnCr5 rhuab mus rau 850 degree mus rau 880 degree yog sai txias kom tau siab hardness thiab lub zog.
2. Tempering: Tom qab quenching, cov khoom yog rhuab mus rau ib tug kub ntawm 150 degree mus rau 300 degree, tuav rau ib lub sij hawm ntawm lub sij hawm, thiab ces txias. Tempering tuaj yeem txhim kho qhov toughness thiab cuam tshuam ntawm 20MnCr5.
