Kev kho cua sov rau SA387 Chrom Moly Alloy Steel Phaj

Chrome moly alloy steel phaj nyob rau hauv ASME SA387 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]
22, 22L, 21, 21L thiab 9	1250 [675]
5	1300 [705]
