DIN 17175 13CrMo44 Alloy Pipes

Seamless heat‑resistant alloy steel tubes manufactured to DIN 17175 in grade 13CrMo44, engineered for demanding high‑temperature and high‑pressure environments (service temperatures up to 600 °C). These tubes are produced as seamless pipes to ensure uniform mechanical properties and long‑term creep resistance required for boiler, pressure‑vessel and pipeline applications.

Key features

• Standard: DIN 17175
• Steel grade: 13CrMo44 (heat‑resistant alloy for elevated‑temperature service)
• Service temperature: up to 600 °C (depending on design and operating conditions)
• Manufacture: seamless construction for improved integrity under pressure and thermal stress
• Surface finish: supplied oiled or black‑painted to prevent rust during storage and transit
• Marking: per customer requirements

Available supply and processing options

• Heat treatment (full length as required): normalizing, subcritical annealing, hardening and tempering with continuous cooling, or hardening and tempering with isothermal treatment — selected according to the steel type and customer specification
• Sizes: available in a range of diameters and wall thicknesses (wall thicknesses up to 28 mm are offered); final dimensions, tolerances and lengths supplied on request
• Quality control: tubes are produced under controlled metallurgical and process conditions; inspection and test documentation can be supplied as required for B2B projects

Typical applications

• Construction of boilers and superheaters
• High‑pressure and high‑temperature pipelines
• Pressure vessels and headers
• Any equipment requiring heat‑resistant steel for operation at elevated temperatures and simultaneous high pressures

Ordering information

When requesting a quotation, please provide: required standard (DIN 17175), outer diameter and wall thickness, length per piece, quantity, required heat treatment, surface finish and any marking or certification requirements. Technical datasheets, mechanical/chemical test reports and special inspection certificates can be provided upon request to support procurement and qualification.
