8620 Kub Rolled Round Bar
SAE 8620 alloy steel yog ib qho tsis tshua muaj hlau npib tsib xee, chromium, molybdenum rooj plaub-hardened steel, feem ntau muab rau hauv cov txheej txheem dov, mus rau qhov siab tshaj plaws hardness ntawm HB 255max. SAE 8620 alloy steel muaj lub zog sab nraud thiab lub zog zoo sab hauv, ua rau nws hnav-tiv taus. SAE 8620 steel muaj lub zog tseem ceeb dua qib 8615 thiab 8617.

Alloy 8620 Steel Product Details
Alloy 8620 tuaj yeem hardened los ntawm cua sov rau 1500 F thiab tom qab ntawd dej quenching. Carburize nyob rau hauv ib tug haum carburizing nruab nrab ntawm 1650 rau 1700 F thiab ces roj quench harden. Txhim kho carburized plhaub thiab cov khoom tseem ceeb tuaj yeem tau txais los ntawm qhov cub txias los ntawm carburizing ntawm 1650 - 1700 F thiab tom qab ntawd rov ua dua rau 1575 F.
AISI 8620 steel yuav austenitise nyob ib ncig ntawm 840 degree - 870 degree thiab yuav roj lossis dej quenched nyob ntawm qhov loj thiab qhov nyuaj ntawm ntu. Yuav tsum tau txias hauv huab cua lossis roj.
Kev kho cua sov ntawm SAE 8620 steel (tsis yog carburized) thiab tempering ntawm cov dej-quenched qhov chaw yog ua ntawm 400 F mus rau 1300 F los ua kom lub ntsej muag toughness nrog tsawg heev rau nws hardness. Qhov no tseem yuav txo tau qhov kev sib tsoo tawg.
AISI 8620 steel tuaj yeem ua tiav los ntawm cua sov mus rau 820 degree - 850 degree thiab tuav kom txog thaum qhov kub thiab txias tsis sib xws thoob plaws hauv seem, tom qab ntawd txias hauv lub cub tawg lossis cua txias.
