Does 09MnNiDR belong to the 2.5Ni or 3.5Ni category? Or something else? Are there any written standards?

Take a look at this standard to find out – GB3531-2014, steel plates for low-temperature pressure vessels

I checked the Ni content; the Ni content in 09MnNiDR is very low, and it does not fall within the 2.5Ni range. So which grade corresponds to 2.5Ni?

According to GB3531-2014, steel plates for low-temperature pressure vessels – 09MnNiDR falls into the 0.5Ni category. 08Ni3DR belongs to the 3.5Ni category, while 06Ni9DR belongs to the 9Ni category. Other types are rare; it is not clear whether they fall under other categories.
