P500QL1 thiab P690QL1 yog cov qauv tsim rau siab -lub zog, weldable, zoo- cov hlau phaj ua raws li EN 10028-6 tus qauv rau lub nkoj siab thiab boilers, qhov twg 'P' txhais tau hais tias siab, '500' / '690' Q, thiab qhov tsawg kawg nkaus lub zog qhia tau hais tias MP tempered, thiab 'L1' qhia qis-kub qhov cuam tshuam toughness (Charpy-V ntawm -40℃nrog 27J tsawg zog). Lawv tau siv rau hauv cov ntawv thov uas xav tau lub zog siab, weldability, thiab ua haujlwm rau qhov txias txias, nrog P690QL1 muab lub zog ntau dua li P500QL1.
