DIN 17175 15Mo3 Seamless Pipes

Seamless alloy-steel tubes manufactured to DIN 17175 (grade 15Mo3) for high-temperature, high-pressure applications. 15Mo3 is a molybdenum-bearing, heat-resistant carbon steel specified in DIN 17175 for use where elevated-temperature strength and scaling resistance are required. These seamless pipes are suitable for boilers, headers, heat exchangers, pressure vessels and pipelines operating at service temperatures up to 600 °C.

Key features

• Conforms to DIN 17175 (steel grade 15Mo3)
• Designed for high-temperature service (up to 600 °C) and elevated pressures
• Seamless construction for improved strength and pressure resistance
• Supplied with surface protection (oiled or black painted) to prevent rust
• Marking and final finish per customer specification

Typical applications

• Boiler tubes and headers
• Steam pipelines and high-temperature process lines
• Pressure vessels and heat exchangers where scale formation and temperature creep must be considered

Available options and supply conditions

• Dimensions: outer diameter and wall thickness made to order; wall thickness offered up to 28 mm (please specify OD × T when enquiring)
• Surface finish: oiled or black painted to protect against corrosion during storage and transit
• Heat treatment/delivery conditions: tubes are supplied fully heat treated; available heat treatments include normalizing, subcritical annealing, hardening and tempering with continuous cooling, and hardening and tempering with isothermal treatment (chosen according to steel type and customer requirements)
• Marking: applied per customer requirement to ensure traceability

Ordering guidance

When requesting a quote, please specify the DIN standard (DIN 17175), steel grade (15Mo3), required dimensions (OD × wall thickness), desired heat treatment/delivery condition, surface finish, marking/traceability requirements, and any required inspection or test certificates. This information ensures accurate pricing, lead time and compliance with your application needs.
