Kev Kho Mob Kub rau A387 Chrom Moly Alloy Steel Plate

Cov hlau chrome moly alloy raws li ASTM A387 yuav tsum yog cov hlau tua, nrog rau kev kho cua sov los ntawm kev annealing, normalizing thiab tempering. Los yog yog tias tus neeg yuav khoom pom zoo, ua kom txias sai los ntawm qhov kub austenitizing los ntawm cua blasting lossis kua quenching, ua raws li tempering, qhov kub tsawg kawg nkaus tempering yuav tsum yog raws li hauv qab no:

Qib	Kub, °F [°C]
2, 12 thiab 11	1150 [620]
22, 22L, 21, 21L thiab 9	1250 [675]
5	1300 [705]

Cov phaj hlau alloy qib 91 yuav tsum tau kho cua sov los ntawm kev ua kom zoo thiab ua kom sov lossis los ntawm kev ua kom txias sai los ntawm kev tua cua lossis kua quenching, ua raws li kev ua kom sov. Cov phaj qib 91 yuav tsum tau austenitized ntawm 1900 txog 1975 ° F [1040 txog 1080 ° C] thiab yuav tsum tau tempered ntawm 1350 txog 1470 ° F [730 txog 800 ° C]

Qib 5, 9, 21, 21L, 22, 22L, thiab 91 daim hlau uas tau txiav txim yam tsis muaj kev kho cua sov los ntawm lub rooj saum toj no, yuav tsum ua tiav rau hauv qhov kev ntxhov siab lossis annealed mob.
