Durehete Standards

The Durehete grade family is governed by three principal specifications. EN 10269 is the primary European standard for alloy steels for fasteners with elevated- or low-temperature properties. VdTUV-Werkstoffblatt W350 is the German pressure-equipment register that publishes the full creep-rupture dataset. ASTM A193 Grade B16 is the closest US equivalent (1Cr-0.5Mo-V chemistry) for projects specified to the ASME B31.1 / B31.3 framework.
