FAQs：

1.What are the heat treatment requirements for steel pipes in DIN 17175?
Requirements vary for different steel grades and may include normalizing, annealing, and tempering (quenching and tempering).

2.What’s the difference between DIN 17175 and DIN EN 10216-2?
Both standards cover seamless steel tubes used for high-temperature applications such as boilers and superheaters. However, DIN 17175 is a German standard, while DIN EN 10216-2 is a European Union standard. Due to their different issuing organizations, their technical requirements and test methods may differ.
