Impact (J): 23
Hardness (Anealed Condition): Tsawg dua los yog sib npaug rau 241HB
300m steel yog ib hom uas tsis tshua muaj alloy siab zog steel, tau dhau los ua lub ntiaj teb lub zog siab tshaj plaws, kev ua tau zoo tshaj plaws, kev siv dav tshaj plaws yog ib qho zoo tshaj plaws iav steel thiab lub koob npe nrov. toughness, qaug zog kev ua tau zoo thiab zoo corrosion kuj, thiab lwm yam nyob rau hauv Tuam Tshoj nyob rau hauv nruab nrab - 80 - s pib AMS6417 theej los ntawm American aerospace khoom tus qauv, thiab nyob rau hauv 1990 los ntawm metallurgical thiab ob leeg kev ntsuam xyuas ntawm aeronautics thiab astronautics
AISI 4340 ultra siab zog tensile steel round bar rau aerospace daim ntawv thov
Cov Qauv: ASTM, JIS, GB, EN (DIN, BS, NF) Los yog Raws li cov neeg siv khoom xav tau.

Cov Khoom Siv Khoom Siv
4340M steel USES lub tshuab nqus tsev arc melting tshuab los txhim kho purity, plasticity, toughness, thiab lwm yam. Lwm qhov chaw ntawm tus qauv siv lub tshuab nqus tsev smelting kom ua tiav qib siab aviation zoo.
Los ntawm cov txheej txheem kev kho cua sov cov roj quenching thiab tempering, lub zog tensile ntawm cov hlau tuaj yeem ncav cuag ntau dua 1860MPa, uas tam sim no yog lub zog siab tshaj plaws ntawm cov hlau tsis tshua muaj zog ultra-siab. Lub zog siab tuaj yeem txo qhov hnyav ntawm qhov chaw, kev txhim kho lub zog tau yog ib lub hom phiaj tseem ceeb ntawm kev tsaws iav qhov chaw tsim. Lub ntsiab tis bearing Cheebtsam ntawm American aircraft kuj yog 300M steel thiab siv rau lub siab tshaj plaws lub zog.
Kev tshuaj xyuas
Kev qaug zog tsis kam ntawm 4340M steel yog pom tseeb zoo dua li ntawm 4340. Qhov no yog qhov muaj txiaj ntsig zoo rau lub neej ntev ntawm cov iav tsaws thiab lwm yam khoom siv dav hlau thiab yog qhov laj thawj tseem ceeb vim li cas 300M hlau tau dav siv hauv dav hlau.
Nws muaj 1.5 feem pua silicon, uas txhim kho cov kev ntxhov siab corrosion ntawm 300M steel.
