SAE 4340 Alloy Steel Bar, tseem hu ua 4340 Alloy Qws, yog tus hwm -qib nickel-chromium-molybdenum alloy steel dav lees paub rau nws lub zog zoo, toughness, thiab qaug zog ua haujlwm. Nrog kev sib npaug ntawm cov khoom siv kho tshuab thiab ua tau zoo los ntawm - muaj peev xwm hardening, nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv hluav taws xob tseem ceeb.
Ntawm Jiangsu Cunrui Hlau Khoom Co., Ltd., peb 4340 Alloy Steel Bars yog tsim raws li thoob ntiaj teb cov qauv xws li ASTM A29, SAE J404, thiab EN 10083. Txhua pawg tau txais kev txhawb nqa nrog cov ntawv pov thawj zeb, cov ntaub ntawv qhia txog tshuaj lom neeg, thiab thib peb - kev tshuaj xyuas yog tias xav tau. Cov khoom siv ua kom ntseeg tau kev ua tau zoo nyob rau hauv kev kho cua sov thiab muaj kev hnav zoo heev thiab ua haujlwm ntev hauv qhov xav tau ib puag ncig.
