Dab tsi yog cov khoom ntawm P235GH?
P235GH yog ib qho uas tsis yog- alloy structural steel seamless yeeb nkab khoom nyob rau hauv cov txheej txheem European tsim los rau siab - kub thiab siab - cov kabmob ib puag ncig. Nyob rau hauv nws lub npe convention, "P" sawv cev rau siab hlab ntsha hlau, "235" qhia qhov tsawg kawg nkaus yield zog ntawm 235 MPa ntawm chav tsev kub, thiab "GH" qhia hais tias cov khoom yog haum rau kub ua hauj lwm tej yam kev mob. Los ntawm cov txheej txheem kev tswj hwm kev sib xyaw thiab kev kho cua sov (feem ntau yog xa hauv lub xeev normalized), cov khoom no muaj cov yas zoo, toughness, txias dabtsi yog khoov zog, thiab weldability, ua rau nws tshwj xeeb tshaj yog haum rau ntev - lub sij hawm ruaj khov nyob rau hauv qhov kub thiab txias ib puag ncig.

P235GH vs P235TR1
| Feature | P235GH | P235TR 1 | Qhov txawv tseem ceeb |
|---|---|---|---|
| Txuj | TS EN 10028-2 Cov Khoom Siv Hluav Taws Xob | TS EN 10216-1 Seamless steel raj rau lub hom phiaj siab | P235GH feem ntau yog siv rau cov khoom tiaj tus (phaj, nplooj ntawv), thaum P235TR1 yog teev rau seamless hlab. |
| Kev kho cua sov | Normalized los yog normalized dov (N / N Normalization) | Feem ntau muab rau hauv +N (Normalized) lossis + AR (Raws li - dov, tab sis tsawg dua) | Ob leeg tuaj yeem ua rau normalization, tab sis P235TR1 feem ntau muab tshwj xeeb rau hauv cov hlab ntsha. |
| Tshuaj muaj pes tsawg leeg | Zoo sib xws hauv paus muaj pes tsawg leeg (C, Mn, P, S txwv), tab sis P235GH yuav muaj kev nruj me ntsis ntawm qee cov ntsiab lus rau cov khoom tiaj tus. | Zoo sib xws, tab sis optimized rau raj ntau lawm; tej zaum yuav muaj kev txwv me ntsis rau cov kab lus kom ntseeg tau tias weldability thiab toughness nyob rau hauv tubular daim ntawv. | P235GH thiab P235TR1 muaj cov tshuaj lom neeg zoo sib xws, tab sis qhov kev tso cai rau qee lub ntsiab lus yuav txawv me ntsis vim cov khoom siv (paj vs. tubular). |
| Mechanical Properties | Yield zog: Ntau dua los yog sib npaug rau 235 MPa Tensile zog: 360-480 MPa Elongation: Ntau dua lossis sib npaug li 22% (rau daim hlau / ntawv) |
Yield zog: Ntau dua los yog sib npaug rau 235 MPa Tensile zog: 360-480 MPa Elongation: Ntau dua lossis sib npaug li 20% (rau cov raj, nyob ntawm txoj kab uas hla thiab tuab) |
Cov cuab yeej cuab tam yuav tsum zoo sib xws, tab sis qhov tsawg kawg nkaus elongation qhov tseem ceeb yuav txawv me ntsis vim yog cov khoom sib txawv thiab cov qauv kev sim. |
| Daim ntawv thov | Boilers, siab hlab ntsha, tshav kub exchangers, thiab lwm yam khoom siv siab uas cov khoom tiaj tus tsim nyog. | Seamless raj rau lub hom phiaj siab, xws li hauv boilers, tshav kub exchangers, thiab lwm yam tshuab uas yuav tsum tau tubular Cheebtsam. | Thawj qhov sib txawv yog nyob rau hauv daim ntawv ntawm cov khoom thiab cov kev siv tshwj xeeb uas lawv tau tsim rau. P235GH yog rau cov khoom tiaj tus, thaum P235TR1 yog rau seamless raj. |
| Toughness Requirements | Zoo toughness ntawm chav tsev kub thiab siab kub, nrog rau kev ntsuam xyuas feem ntau yuav tsum tau. | Kuj yuav tsum tau zoo toughness, tshwj xeeb tshaj yog nyob rau hauv qis kub rau tej daim ntawv thov; kev ntsuam xyuas tej zaum yuav raug teev nyob ntawm tus qauv thiab cov neeg siv khoom xav tau. | Ob leeg steels yuav tsum tau zoo toughness, tab sis cov kev cuam tshuam kev soj ntsuam yuav tsum tau sib txawv raws li cov khoom tus qauv thiab daim ntawv thov npaj. |
| Weldability | Zoo weldability nrog cov txheej txheem tsim nyog. | Weldability zoo heev, uas yog ib qho tseem ceeb rau tubular Cheebtsam uas yuav welded ua ke. | Ob lub steels yog weldable, tab sis P235TR1 lub weldability yog ib qho tseem ceeb tshwj xeeb vim nws feem ntau siv hauv welded raj sib dhos. |
