The grade of Q490DRL2 steel is composed of the initial letter "Q" of the small strand of strong numerical force container "Rong" on behalf of the yield strong "Qu", or the initial spelling of the low temperature pressure vessel "low" "DR" grade "L".

Example, Q490DRL2. thereinto

Yield strength: The first letter of the Chinese pinyin alpha of the word "yield".

490 – Specify the lower limit of flexion strength in megapascals (MPa)

DR - Low temperature pressure capacity "容" in Chinese pinyin.

One by one temperature level L1 represents a 40 C requirement, L2 represents a 50 C requirement,

For the large wire can be welded requirements, the first letter "w" of the English single "Wed" representing the large wire can be connected to the word "" is added after the above-mentioned grade, such as Q490RW

Q490DRL2 steel plate implementation standard: implement GB/T713-2023 standard.
