1. Hais txog dej hiav txwv, xav txog cov dej xiav thiab txhua yam ntawm cov dej hiav txwv. Yog, kuj tseem muaj cov nkoj thiab cov khoom siv steel phaj. Niaj hnub no peb yuav kawm txog ntau yam ntaub ntawv. CCS/DH36, CCS/EH36, CCS/FH36.
2. Cov ntaub ntawv piav qhia: D, E, F yog cov qib zoo, thiab qhov cuam tshuam kub yog: -20, -40, -60. H yog cov khoom siv hauv tsev muaj zog, nrog qhov siab tshaj plaws compression tsis kam ntawm 36. Z yog Z-kev taw qhia kev ua tau zoo, piv txwv: CCS/DH36-Z15, CCS/DH36-Z25, CCS/DH 36-Z35, thiab lwm yam.
3. Cov qauv txheej txheem tsim nyog tau ua raws li GB/T712-2011 cov qauv.
4. Cov txheej txheem kho cua sov ntawm peb cov ntaub ntawv no txawv: DH36 tuaj yeem raug annealing, kub dov, normalizing, tswj dov, TM thiab lwm yam kev kho cua sov; EH36 feem ntau normalized, TM txheej txheem; FH36 feem ntau normalized, TM, quenched thiab tempered. Txheej txheem; Lus Cim: Cov thicknesses sib txawv yuav muaj cov txheej txheem kev kho cua sov sib txawv.
5. CCS/DH36, CCS/EH36 thiab CCS/FH36 yog dab tsi?
