Kev kho cua sov rau A387 Chrom Moly Alloy Steel Phaj

Chrome moly alloy steel phaj nyob rau hauv ASTM A387 yuav tsum raug tua hlau, nrog thermally kho los ntawm annealing, normarlizing thiab tempering. Los yog nyob rau hauv cov ntaub ntawv pom zoo los ntawm buyer, ceev ceev txias los ntawm lub austenitizing kub los ntawm huab cua blasting los yog kua quenching, ua raws li los ntawm tempering, yam tsawg kawg nkaus tempering kub yuav tsum tau raws li hauv qab no cov lus:

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

Qib 91 alloy steel daim hlau yuav tsum tau kho cua sov los ntawm normalizing thiab tempering los yog ceev cua txias los ntawm huab cua blasting los yog kua quenching, ua raws li tempering. Qib 91 daim hlau 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 txiav txim yam tsis muaj kev kho cua sov los ntawm cov lus saum toj no, yuav tsum ua kom tiav nyob rau hauv qhov kev ntxhov siab los yog kev mob annealed.
