P355Q steel phaj yog weldable, nplua - nplej, quenched thiab tempered steel rau cov khoom siv siab, ua tau raws li European tus qauv EN 10028-6, paub txog kev weldability zoo heev, plasticity, thiab cuam tshuam lub zog, nrog rau qhov tsawg kawg nkaus lub zog ntawm 355 MPa (li no "355"). Nws yog siv nyob rau hauv high-temperature siab hlab ntsha, boilers, thiab lwm yam kev thov uas yuav tsum tau muaj zog thiab kev ntseeg tau, feem ntau muab raws li P355QH los yog P355QL1 / QL2 variants rau txawv tej yam toughness theem.
