EN 10216-2 13CrMo4-5 1.7335 Seamless Boiler Tubes For Performance In High-Temperature
EN 10216-2 13CrMo4-5 (1.7335) seamless tubes are engineered for high-pressure, high-temperature applications in energy and industrial sectors. Their balanced composition of chromium and molybdenum ensures reliable performance in steam and boiler systems.
13CrMo4-5 is a low alloy chromium-molybdenum steel optimized for high temperature applications.
Excellent creep strength and thermal fatigue resistance at elevated temperatures.
Better oxidation resistance in steam environments than ordinary carbon steels (e.g. P235GH).
High temperature strength: Mechanical properties are maintained up to 600°C (1112°F).
Creep resistance: Suitable for long term high temperature stress environments.
Good weldability: Requires pre- and post-weld heat treatment to avoid cracking.
Corrosion resistance: Moderate resistance to oxidation and scaling in steam/boiler environments.
