Q580R grade expression method

Q - a yield strength of the first letter of the word "yield" in Chinese pinyin;

580 – the lower limit of the specified yield strength in megapascals (MPa);

R - the first letter of the Chinese pinyin of the pressure vessel "Rong".

The chemical composition of Q580R steel plate The chemical composition

of Q580R steel plate shall comply with the provisions of the new national standard GB/T713.6-2023 "Steel plate and strip steel for pressure equipment Part 6: quenched and tempered high-strength steel".
