JIS G4053 SNCM 439 alloy steel yeeb nkab muab los ntawm GNEE muaj lub zog siab, hardness, hnav tsis kam thiab zoo toughness, tshwj xeeb tshaj yog nyob rau hauv kev tsim khoom ntawm cov khoom siv thiab cov khoom siv rau cov khoom siv siab. Nws hardenability yog me ntsis siab dua 40Cr, thiab qhov tseem ceeb quenching txoj kab uas hla ntawm cov roj yuav ncav cuag 18-33 hli.
JIS G4053 SNCM439 seamless alloy steel yeeb nkab feem ntau yog siv rau hauv lub xeev tempered, thiab kev khiav hauj lwm kub yog -20-425 degree . Nws yog dav siv nyob rau hauv qhov chaw uas yuav tsum tau muaj zog, siab toughness, loj cross-sectional qhov ntev thiab tseem ceeb quenching thiab tempering.
