16MnR (HIC) low-alloy high-strength plate steel

16MnR (HIC) Low Alloy High Strength Plate Steel
16MnR (HIC) is a steel plate for hydrogen sulfide corrosion resistance. As a steel material for nuclear power, 16MnR(HI)C, also known as 16MnHR, cooperates with the development of China's nuclear power, thermal power and hydropower industries to develop 16MnRHIC steel plates with a yield strength of 235MPa-1000MPa.
Nuclear power steel mainly includes 20HR, 20MnHR, 16MnHR and other grades of steel plate thickness of 8-250mm, steel plate width of 1300-4000mm,
steel plate length of 4000-18500mm

Note:
(1): In order to improve the properties of steel, other trace alloying elements other than the above table can be added, and the data comes from the network and is for reference only.
(2): The allowable deviation of the chemical composition of the finished steel plate shall comply with the provisions of
GB/T222 16MnR (HIC) steel plate smelting method: smelting by electric furnace + LF/VD furnace external refining method, the steel plate is sprayed with calcium in the smelting process to control its inclusion form, and it should be an essentially fine-grained calming steel. Its actual grain size is grade 5 or above.
