ASME SA387 GR.11 CL2 Siab Vessel Steel phaj

Lub nkoj siab siv hlau phaj SA387 Qib 11 CL 1, SA387 Qib 11 CL 2, A387 Qib 11 CL 1 thiab A387 Qib 11 CL 2 yog nrog Chromium-Molybdenum alloy ntsiab.Pressure nkoj steel phaj SA387 Qib 11 SA18 1 thiab CL 2 yog nyob rau hauv American standard ASME SA 387 / SA 387M.Boiler steel phaj A387 Qib 11 Cl 1 thiab A387 Qib 11 Cl 2 yog raws li ASTM A387 / A387M.Cov ntaub ntawv steel kuj yuav tsum ua raws li steel specification A 20 /A 20M.Cov kev cai no qhia txog cov kev sim thiab rov ntsuas cov txheej txheem thiab cov txheej txheem, tso cai hloov pauv ntawm qhov ntev thiab qhov hnyav, zoo thiab kho qhov tsis xws luag, kos npe, thauj khoom, thiab lwm yam.

Ntxiv rau cov kev cai yooj yim ntawm cov lus qhia no rau steel phaj SA387 Qib 11 CL 1, SA387 Qib 11 CL 2, A387 Qib 11 CL 1 thiab A387 Qib 11 CL 2, qee qhov kev xav tau ntxiv muaj nyob rau thaum muaj kev tswj xyuas ntxiv, kuaj, lossis kev kuaj xyuas. kom ua tau raws li cov cai siv. Cov no suav nrog: 1 Kev kho lub tshuab nqus tsev, 2 Kev sim ntxiv lossis tshwj xeeb nro, 3 Kev sim cuam tshuam, 4 Kev kuaj tsis muaj kev puas tsuaj

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]
