What is DIN 17175 material?
DIN 17175: German industrial standard, specifically designed for heat-resistant steel boiler tubes, suitable for boiler heating surface components (such as economizers and superheaters) with working pressures ≤5.88MPa (low/medium pressure) to ≥9.8MPa (high pressure) and temperatures 450-650°C, and for petrochemical pipelines.
