What are the performance differences between sa516gr70 and 16Mn?
The chemical composition is similar, and the material properties are similar as well, but they are not identical
Logically, there isn’t much difference – they are well-known and top-tier brands in the domestic market. When it comes to performance differences, it depends on the criteria used for evaluation. The ASME standards result in significantly lower performance for Q345R, and there are also strict limits on the operating temperatures. There’s nothing to do
SA516Gr70 is a carbon steel plate intended for use in medium and low-temperature pressure vessels, in accordance with ASME standards. It differs from SA516Gr60 in terms of its tensile strength.
