P235GH TC1 yog dab tsi?
P235GH TC1 steel yeeb nkab yog cov yeeb nkab uas tsis yog- alloy steel yeeb nkab, feem ntau yog siv rau hauv cov kav dej siab thiab cov tshuab boiler, uas yog cov pa nruab nrab thiab qhov kub thiab txias siab -cov xwm txheej ntawm cov kabmob (xws li kev ua haujlwm zoo tib yam thiab cov kav dej dav hlau).
Qhov txawv ntawm P235GH, TC1, thiab TC2 yog dab tsi?
| Feature | P235GH TC1 | P235GH TC2 | Qhov txawv tseem ceeb |
|---|---|---|---|
| Kev kho cua sov | Normalized (N) los yog normalized thiab tempered | Yuav tsum yognormalized (N) | TC 2yuav tsum normalization, thaum TC1 tso cai rau lwm yam kev kho mob xws li - dov (yog tias tau teev tseg). |
| Yuav tsum muaj kev ntsuam xyuas qhov cuam tshuam | Kev ntsuam xyuas cuam tshuamtsis yuamtshwj tsis yog tias tau teev tseg los ntawm tus neeg siv khoom | Yuav tsum tau kuaj qhov cuam tshuamntawm qhov ntsuas kub (piv txwv li, 0 degree, -20 degree, lossis raws li kev pom zoo) | TC2 muajstricter toughness xav taulos xyuas kom meej tias kev ua tau zoo nyob rau hauv qis -kev siv kub. |
| Toughness (Charpy V-notch) | Tsis muaj guaranteed yam tsawg kawg nkaus lub zog | Yam tsawg kawg nkaus muaj nuj nqis zogyuav tsum tau (piv txwv li, 27 J ntawm qhov ntsuas kub) | TC2 yog tsim los rauqhov chaw txias duaqhov twg brittle fracture pheej hmoo siab dua. |
| Daim ntawv thov | Cov cuab yeej siv siab dav dav, boilers, thiab cov khoom siv hluav taws xob uas tsis tshua muaj - kub toughness tsis tseem ceeb | Tsawg-kev pabcuam kub, xws li nyob rau hauv huab cua txias, tshuab tub yees, los yog offshore daim ntaub ntawv | TC2 yog qhov zoo dua thaumkev khiav hauj lwm kub yog tsawglos yog thaumkev ruaj ntseg tiv thaiv brittle puasyog qhov tseem ceeb. |
| Quality Assurance | Basic mechanical thiab chemical xav tau | Txhim kho kev simrau cov khoom cuam tshuam | TC2 suav nrogkev kuaj ntxivlos xyuas qhov toughness, nce nqi ntau lawm. |
