The chemical composition of DIN17175 mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other elements. The specific content range will vary depending on different material pands. For example, some grades may be resistant to chromium (Cr), molybdenum (Mo), copper (Cu), nickel (Ni), vanadium (V), aluminum (Al), tungsten (W), titanium (Ti), niobium (Nb) ), nitrogen (N) and other elements also have specific content requirements.
Steel pipes under the DIN17175 standard are mainly produced by centrifugal casting and rolling.
Steel pipes under the DIN17175 standard have several distinctive features that make them particularly suitable for high-pressure boilers and other high-temperature and high-pressure environments.
1. Has excellent high temperature resistance. Made from specific heat-strength steel, these pipes are able to operate reliably at operating temperatures up to 600°C without significant performance degradation or structural changes.
2. Have good pressure bearing capacity. They are carefully designed and manufactured to withstand various stresses in high-pressure working environments to ensure safe operation of equipment.
3. It has good corrosion resistance and oxidation resistance, and can be used for a long time in harsh working environments without being easily damaged.
4. Has high mechanical properties. It has excellent mechanical properties such as tensile strength, yield strength and impact toughness. This enables them to withstand various complex mechanical effects and maintain stable structural form and performance.
DIN17175 has a wide range of applications, mainly in high temperature and high pressure industrial environments. Specifically, it is mainly used in the manufacture of heating surface tubes, economizers, superheaters, reheaters and other components of high-pressure boilers (working pressure is generally above 9.8Mpa, working temperature is between 450℃ and 650℃).
