4130 Steel yog dab tsi?
AISI 4130 alloy steel yog nruab nrab carbon, qis alloy steel hauv ASTM A29 tus qauv. ASTM 4140 steel kuj feem ntau hu ua chromoly steel, lossis chrome moly steel, muaj npe 0.28-0.33% Carbon, 0.8-1.1% Chromium thiab 0.15-0.25% Molybdenum. Nws zoo ib yam li 4140 steel uas muaj cov pa roj carbon ntau dua (0.28-0.33%), muab 4130 cov khoom txhim kho weldability, ntawm qhov kev siv nyiaj los ntawm lub zog tuab. Nrog rau kev kho cua sov kom zoo nws kuj tau yooj yim machined. Annealing ASTM 4130 alloy steel muaj ductility zoo heev. AISI 4130 steel feem ntau yog muab raws li puag ncig bar feem ntau nyob rau hauv lub hardened thiab tempered mob.
AISI / SAE 4130 steel qib yog ntau yam alloy nrog zoo atmospheric corrosion tsis kam thiab tsim nyog lub zog mus txog 315º C (600º F). Nws qhia tau hais tias zoo tag nrho kev sib txuas ntawm lub zog, toughness thiab qaug zog.
