SA387 GR.12 CL1 Alloy Pressure Vessel steel phaj

A387Gr12CL1 siab lub nkoj steel phaj muaj qhov tsawg kawg nkaus lub zog ntawm 275 Mpa, thiab lub zog tensile nyob rau hauv 450-585 Mpa. SA387 Qib 12 CL 1 yog nyob rau hauv American standard ASME SA 387 / SA 387M.Boiler steel phaj A387 Qib 12 Cl 1 yog raws li ASTM A387 / A387M. Cov ntaub ntawv hlau no kuj yuav tsum ua raws li cov lus qhia steel A 20 / A 20M. Cov kev cai no qhia txog cov kev sim thiab rov ntsuas cov txheej txheem thiab cov txheej txheem, kev tso cai hloov pauv hauv qhov ntev thiab qhov hnyav, zoo thiab kho qhov tsis xws luag, kos npe, thauj khoom, thiab lwm yam.

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]
