42crmo4 puag ncig bar

Khoom Description

42crmo4 steel yog cov khoom siv hlau. 42crmo4 puag ncig bar yog siv los tsim cov forgings uas yuav tsum tau muaj zog dua thiab loj dua quenched thiab tempered seem tshaj 35CrMo steel, xws li lub zog loj rau locomotive traction, booster kis gears, rear qag, hnyav loaded txuas rods, thiab caij nplooj ntoos hlav clips. 42CrMo4 steel kuj tseem siv tau rau cov roj sib sib zog nqus tho yeeb nkab txuas thiab cov cuab yeej nuv ntses hauv qab 2000m.

42CrMo4 (1.7225 khoom) muaj lub zog siab, toughness, zoo quenching kev ua tau zoo thiab temper brittleness. Tom qab quenching thiab tempering tshav kub kho, 42crmo4 round bar tuaj yeem tswj tau qhov cuam tshuam zoo thiab tsis tshua muaj kev kub nyhiab, yog li ua tiav qhov siab qaug zog tsis kam. 42crmo4 qt khoom yog tsim rau kev tsim cov yas pwm loj thiab nruab nrab, kis tau tus mob, lub qag nram qab, cov kabmob sib txuas, lub caij nplooj ntoos hlav snap springs, thiab sib sib zog nqus cov yeeb nkab sib txuas hauv cov roj qhov dej uas yuav tsum tau muaj zog thiab toughness.

Feature:
1. 42crmo4 round bar muaj zog zoo, hardenability thiab toughness.
2. Nyob rau hauv qhov kub thiab txias, 42crmo4 steel ua kom muaj zog creep thiab ntev lub zog.

Kev siv:
42crmo4 qt khoom siv los tsim cov khoom loj, cov duab zoo thiab cov cuab yeej muaj txiaj ntsig (xws li, scraper, iav, milling cutter, drilling, tapping, thiab lwm yam.) Txias forging tuag, forging cov cuab yeej; Sawb txiav tshuab, taub hau sib sau tuag.
