American standard carbon seamless steel kav yog kuaj rau txhua yam khoom. Cov kev sim ntawm cov cuab yeej siv tshuab tau muab faib ua ob pawg, ib qho yog kev sim tensile thiab lwm yam yog kev sim hardness.
Kev ntsuas tensile yog ua kom cov yeeb nkab steel seamless rau hauv cov qauv, thiab siv lub tshuab ntsuas tensile los rub cov qauv mus rau qhov tawg, thiab tom qab ntawd ntsuas ib lossis ntau lub zog. Feem ntau tsuas yog lub zog tensile, yield zog, elongation thiab tus nqi ntawm qhov txo qis hauv cheeb tsam. Tensile xeem yog txoj kev yooj yim tshaj plaws rau kev sim cov khoom siv hlau. Yuav luag txhua cov ntaub ntawv hlau xav tau kev ntsuas tensile tsuav lawv muaj cov cuab yeej cuab yeej cuab tam. Tshwj xeeb, kev sim tensile yog tib txoj hauv kev los ntsuas cov khoom siv kho tshuab ntawm cov khoom uas nws qhov nyuaj tsis tuaj yeem kuaj tau yooj yim.
Qhov nyuaj ntawm 40Cr carbon seamless steel yeeb nkab feem ntau tuaj yeem kuaj los ntawm Rockwell hardness, thiab nws qhov hardness ntau yog feem ntau ntawm HRC32-36 (uas yog, ntawm HB301-340).
Tom qab quenching thiab tempering kev kho mob, 40Cr steel muaj zoo zoo txhua yam khoom, tsis tshua muaj kub cuam tshuam toughness thiab tsis tshua muaj notch rhiab heev, thiab cov hlau muaj zoo hardenability. Ntxiv rau quenching thiab tempering kev kho mob, hom hlau no kuj tsim nyog rau cyanidation thiab high-frequency quenching kev kho mob, thiab muaj kev ua tau zoo. 40Cr carbon seamless steel yeeb nkab feem ntau yog siv los tsim cov khoom uas muaj kev ntxhov siab me me thiab kev hnav tsis zoo, xws li tshuab cuab yeej spindles, bushings, zog, thiab lwm yam.
