DIN 17175 Seamless Boiler Tube
Heat-Resistant Steel – Elevated Temperature Service
Product Overview
DIN 17175 is the German standard for seamless heat-resistant steel tubes intended for boilers, superheaters, heat exchangers, and pressure piping at elevated temperatures. These tubes offer excellent creep strength and oxidation resistance for high-temperature service.
Steel Grades: St35.8, St45.8, 15Mo3, 13CrMo44, 10CrMo910
⚠️ Note: DIN 17175 has been withdrawn and replaced by EN 10216-2. We supply both DIN 17175 specified material and its EN 10216-2 equivalents. Contact us for clarification.
✅ Fully traceable with EN 10204 3.1 MTC
✅ Excellent creep strength at high temperatures

FAQ
Q1: Is DIN 17175 still valid?
A: No. DIN 17175 has been withdrawn and replaced by EN 10216-2. However, we still supply material to DIN 17175 specifications for legacy and replacement projects.
Q2: Can I use EN 10216-2 instead of DIN 17175?
A: Yes. EN 10216-2 is the direct replacement with equivalent grades (St35.8 = P235GH, etc.).
Q3: Which grade is most popular for boilers?
A: St35.8 for general service, 13CrMo44 for high-temperature service.
Q4: Do you provide both DIN and EN certificates?
A: Yes. We can provide mill test certificates referencing either standard as required.
Q5: Can you provide third-party inspection?
A: Yes. SGS, BV, TUV, or any customer-specified agency.
Q6: Do you offer free samples?
A: 30cm sample available upon request. Shipping fee applies.
