12MnNiVR is a steel plate for pressure vessels. Compared with the SPV490Q crack sensitivity coefficient Pcm in the Japanese standard JIS G3115, it is lower and more conducive to steel plate welding. The sampling direction of the impact test is changed from longitudinal to transverse, and the impact temperature is changed from -10 degrees to {- 15}} 7d 7d degrees or lower, and the impact power is improved. 12MnNiVR huwa użat fi kbir żejt ħażna tank manifattura.
