304NG Nuclear Grade Stainless Steel Mechanical Properties
Nitrogen Control 304NG Nuclear Grade Stainless Steel Mechanical Properties:
A. Room Temperature
In different standard and specification, the mechanical properties requirement of 304L and 304NG have slight difference. Table 1 show the France RCC-M coefficient. Table 2 shows the industry products measured value.
Table 1 France RCC-M specified the mechanical properties coefficient of Z2CN19-10.
