DIN 17175 Heat-Resistant Boiler Tubes
DIN 17175 seamless heat-resistant steel tubes for boiler installations — St 35.8, St 45.8, 15Mo3, 13CrMo44, and 10CrMo910 for European-engineered thermal power and industrial boiler projects.
DIN 17175 boiler tubes
OVERVIEW
The German boiler tube standard.
DIN 17175 covers seamless tubes made from heat-resistant steels for boiler, superheater, and heat exchanger service. While progressively replaced by EN 10216-2 in European regulatory frameworks, DIN 17175 remains widely referenced in projects with German engineering heritage across Asia, the Middle East, and Africa.
Global Seamless manufactures DIN 17175 equivalent tubes with dual certification to both DIN and EN 10216-2 standards, providing procurement flexibility for projects referencing either specification.
