ASME SA516 Grado 70 (SA516-70)China DFC ofrece
ASME SA516 Grado 70 (SA516-70) mundial. Por favor contáctenos para más información.
Acero al carbono ASME SA-516: el acero de aleación de medio carbono para calderas y recipientes a presión soldados donde la tenacidad de muesca es importante. Viene en cuatro grados, y SA-516 Grade 70 es uno de ellos.
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.

SA516 Gr.70 (ASME) VS 16MnR (Chinese Standard)
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.
SA516 Gr.70 VS SA516 Gr.485
SA516 Grade 70 and
are same. The difference is their units only. Grade 70 is in US unit while Grade 485 is in SI unit.
