4140 steel yeeb nkab belongs rau alloy structural steel. 4140 seamless steel yeeb nkab belongs rau qib US, uas yog sib npaug rau kuv lub teb chaws qib 42CrMo steel. Qhov no steel qib yog nruab nrab hardenable steel, nrog cov ntsiab lus carbon ntawm 0.33% -0.48%, tensile zog ntawm 795MPa, hardness ntawm 241HB, thiab lwm yam. Nws muaj qhov zoo ntawm lub zog yield zog, zoo tag nrho txhua yam khoom. , siab zog, zoo toughness, thiab siab hardenability. Nws tuaj yeem siv los tsim cov khoom siv turbine fasteners, cov cuab yeej khaws cia, thiab lwm yam.
SAE 4140 txias drawn steel yeeb nkab yog ib qho nyuaj tshaj li lwm yam steel qib qauv. SAE 4140 alloy steel yeeb nkab kuj tsim nyog rau cov ntawv thov kub thiab txias forging. GNEE stocks AISI 4140 cov ntaub ntawv nrog lub cheeb ntawm 20mm txog 190mm.
