Qhov sib txawv ntawm P295GH thiab P355GH

Dec 15, 2025 Tso lus

P295GH thiab P355GH yog ob qho tib si tsis yog - alloy steels rau cov hlab ntsha siab (EN 10028-2), tab sis qhov sib txawv tseem ceeb yog lawv.zog: P355GH muaj lub zog qis dua qis dua (nyob ib puag ncig 355 MPa rau cov phaj nyias) piv rau P295GH (ib puag ncig 295 MPa), ua rau P355GH haum rau kev xav tau ntau dua, siab dua - daim ntawv thov siab, nrog P355GH feem ntau xav tau kev kho cua sov rau nws cov khoom, thaum ob qho tib si hauv boilers thiab boilers.
