One of the most prominent steel grades defined under DIN 17243 is (Material Number 1.0460).
: When components fall under mandatory legal tracking, DIN 17243 operates alongside specialized codes of practice like TRD (Technical Rules for Steam Boilers) and TRB (Technical Rules for Pressure Vessels). 2. Core Material Grades and Chemical Composition
This chromium-molybdenum alloy steel falls under the DIN 17243 materials family. It contains 0.15–0.21% carbon, 0.6–0.9% manganese, 0.9–1.2% chromium, and 0.15–0.25% molybdenum, giving it enhanced hardenability and high-temperature strength.
: Covers steel forgings for pressure purposes (specifically ferritic and martensitic steels with specified elevated temperature properties). din 17243 pdf
: A core feature of all steel grades certified under this standard is their proven suitability for fusion welding processes without compromising heat resistance.
Steam turbine rotors, valve bodies, and high-pressure piping.
— Determine whether the material falls under DIN EN 10273 (bars) or DIN EN 10222-2 (forgings). One of the most prominent steel grades defined
