SA516 Gr.70 Recipiente a presión, SA516 Gr.70 fabricante de recipientes a presión

SA-516 Grade 70 cubre una gama de resistencias a la tracción de 55 MPa a 90 MPa y esta versatilidad indica gran parte de la popularidad de las especificaciones.

In general, is considered to be equivalent to SA516 Grade 70. However, 16MnR gets higher yield strength than that of SA516 Gr.70. Compared with SA516 Gr.70, 16MnR's C content is much lower and its Mn content is much higher. Moreover, in China, ASME SA-516 steel is usually used to make exported pressure vessels (design temperature: -20 ℃～-50 ℃) designed for low-temperature working conditions while Chinese 16MnR is not appropriate for low-temperature pressure vessels.
