Kev Kho Cua Sov Rau A387 Chrom Moly Alloy Steel Phaj

Chrome Moly Alloy Steel phaj nyob rau astm AT387 yuav raug tua cov hlau, nrog kho cov khoom siv los ntawm annealing, nationalarlandizing thiab tempering. Los yog nyob rau hauv rooj plaub pom zoo los ntawm cov neeg yuav khoom, nrawm cua txias los ntawm kev kub taub hau lossis kua quenching, ua raws li qhov tempering, qhov ntsuas kub yam tsawg kawg nkaus, ntsuas kub tsawg kawg nkaus
