The latest version is typically purchased through national standards bodies like DIN (Germany) for a particular alloy, such as
Applies to extruded products such as bars (round, square, hexagonal, rectangular), tubes (seamless or porthole), and profiles. Key Metrics: It defines limits for: Tensile Strength ( Rmcap R sub m ): The maximum stress a material can withstand. Yield Strength ( Rp0.2cap R sub p 0.2 end-sub ): The point at which permanent deformation begins. Elongation ( A50mmcap A sub 50 m m end-sub ): How much the material stretches before breaking. en 755-2 pdf free download
