DIN17175 19Mn5 Seamless Tube Description
DIN 17175 19Mn5 is a heat-resistant carbon manganese steel seamless tube in accordance with the German Industrial Standard (DIN) for the manufacture of high-temperature and high-pressure equipment, such as boilers and heat exchangers. heat exchangers.
properties include:
Material Classification: A low alloy heat resistant steel with moderate carbon content (approx. 0.15% to 0.22%) and high manganese content (1.0% to 1.6%) for strength and high temperature stability.
Succession of standards: The DIN 17175 standard is now partially replaced by the EN 10216 series, but 19Mn5 is still widely used in traditional equipment maintenance and specific applications.
Applications:
Energy field: power station boiler ladle, high-pressure steam piping, and heat exchangers.
Chemical equipment: high-temperature reaction vessels, oil, and gas pipelines.
Traditional industry: maintenance and upgrading of old boiler systems.
