DIN 17175 13CrMo44 Seamless Pipe

Seamless, heat-resistant alloy steel tubes manufactured to DIN 17175 in grade 13CrMo44, engineered for high-temperature, high-pressure process systems.

• Standard: DIN 17175
• Steel grade: 13CrMo44 (heat-resistant low-alloy steel)
• Chemical elements covered by the standard: C, Si, Mn, P (≤), S (≤), Cr (see DIN 17175 for limits)
• Dimensions: available in a range of diameters and wall thicknesses (wall thicknesses up to 28 mm). Contact us with required OD × T for availability and lead time.
• Surface finish: oiled or black painted to protect against rust during storage and transport
• Marking: supplied per customer specification

Delivery condition and heat treatment

Tubes are supplied suitably heat treated over their full cross section. Available heat-treatment options (per material/part specification) include:

• Normalizing
• Subcritical annealing
• Hardening and tempering with continuous cooling from the hardening temperature
• Hardening and tempering with isothermal treatment

Typical applications

Designed for use in boilers, steam headers, high-temperature pipelines, pressure vessels and equipment operating up to approximately 600 °C under simultaneous high pressures and cyclic or sustained stresses.

Commercial and quality options

• Custom cutting, end finishing and packaging available for bulk and project orders
• Inspection and test documentation available on request (e.g., material certificates, heat-treatment records, mechanical and chemical test reports)

For a precise quotation, please provide required OD × wall thickness, quantity, delivery terms and any required inspection/certification.
