4340 High Tensile Steel Rods
AISI 4340 steel (UNS G43400) yog ib qho ultra- siab- lub zog nruab nrab- carbon qis- alloy steel uas sib sib zog nqus hardenability, siab ductility, toughness thiab lub zog, thiab muaj zog tiv taus thiab creep kuj. Nws tsis cuam tshuam los ntawm tempering thiab embrittlement, qhia tau hais tias muaj zog zoo tuav ntawm qhov kub thiab txias, thiab tsis yooj yim rau soften. Hauv cov ntu nyias, cov hlau no yog cua tawv. Hauv kev xyaum, nws feem ntau yog roj quenched.
