** 1. Dab tsi yog P265GHGh Cov Khoom Siv? **
P265GHGH yog A ** Tsis-Alloy Steel Qib ** Nkag mus rau hauv European Txheem ** Qhib cov hlau sib tw rau lub hom phiaj siab). Nws yog tsim rau kev pab kub siab, feem ntau yog siv hauv boilers, cov hlab ntsha siab, thiab kev hloov pauv kub. Cov yam ntxwv tseem ceeb suav nrog:
- Yam tsawg kawg nkaus paib zog: ** 265 mpa **
- Zoo creep tsis kam ntawm nce qhov kub (txog ~ 550 degree).
- Muaj pes tsawg leeg suav nrog cov pa roj carbon (c), manganese (mn), silicon (si), thiab kab nqi ntawm chromium (CR), Molybdenum (mo), thiab npib tsib).

** 2. P265Gh yeeb nkab sib npaug rau cov khoom siv ASTM? **
Qhov ze tshaj Astm sib npaug rau P265GHGE yog ** -516}}}}}}}}}} boiler thiab siab lub siab code). Ob qho tib si raug siv rau cov ntawv thov sib xws (boilers) thiab qhia cov khoom sib piv cov khoom thiab qhov kub tsis kam. Txawm li cas los xij, kev sib txig sib luag ncaj qha yog nyob ntawm cov cai tshwj xeeb (piv txwv li, ntsuas kub thiab tuab).

** 3. Dab tsi yog P265Ghgh cov khoom siv? **
Cov khoom siv code ** P265GHGE ** raws cov en (European qauv) tsim:
- ** "P" **: qhia tias cov khoom siv siab.
- ** "265" **: Yam tsawg kawg nkaus tuaj lub zog (265 MPA).
- ** "GH" **: Kev siv qhov kub (** G ** AZ ET ** H ** H ** H ** H ** az thiab aute Température, Fabkis rau "roj thiab kub").

** 4. Dab tsi yog qhov txawv ntawm P235Gh thiab P265GHGE? **
- ** Xij lub zog **:
- P235GH: Yam tsawg kawg nkaus paib zog =}}} ** 235 mpa **.
- P265GHGE: Yam tsawg kawg nkaus paib zog =}} ** 265 mpa **.
- ** Muaj Tshuaj Lom Zem Pib 4 **:
- P265GHGE muaj cov pa roj carbon ntau dua (c) thiab manganese (mn) cov ntsiab lus rau kev txhim kho lub zog.
- ** APP daim ntaub ntawv **:
- P235GH yog siv rau cov ntawv thov txo qis \/ kub thiab P265GHook yog haum rau kev ntxhov siab thiab qhov kub thiab txias.

** 5. P235GH STEEL sib npaug rau? **
The closest ASTM equivalent to P235GH is **SA-516 Grade 60** or **SA-285 Grade C**, depending on the application. Cov qib no muaj cov txiaj ntsig zoo sib xws (220-250 mpa) thiab siv rau hauv boilers thiab siab cov hlab ntsha. Nco ntsoov txheeb xyuas kev sib txig sib luag raws li cov qauv txheej txheem.
