Q500C low alloy high strength plate

Q500C low-alloy high-strength plate, Q is the capital of the first letter of the Chinese pinyin of the word "Qu" for the yield strength of steel; 500 is the yield value, in MPa; C, D, and E are the quality star grades.

Q500C low-alloy high-strength plate implements technical standard specification GB/T1591-2018, low-alloy high-strength structural steel standard and GB/T16270-2009 high-strength structural quenched and tempered steel plate standard.

Q500C low alloy high strength plate can be rolled with Z direction performance, Q500C, Q500C-Z15, Q500C-Z25, Q500C-Z35.
