Ferritic Martensitic Pipes
Reliable Steel is a leading distributors and exporter of Ferritic Martensitic pipes in mostly countries. We offer best quality ferritic martensitic pipes but we are specialised in ASTM A268 pipes of several grades such as TP405, TP409, TP410, 410L, 430, and 446, as well as UNS S44660. These tubes are used for general corrosion and high-temperature applications and are available in seamless or welded forms.

Specification Overview
- Standard: ASTM A268 / ASME SA268 covers a variety of grades of stainless steel tubing for general service.
- Composition: The specification includes ferritic and martensitic grades, which are straight-chromium stainless steels.
- Manufacturing: Tubes are made by either seamless or welded processes, with no filler metal added.
- Applications: These tubes are used in general corrosion-resisting and high-temperature services. Specific applications include heat exchangers, boilers, heaters, and general machining.
Grade-specific characteristics
- TP410: A basic martensitic grade that offers good hardness, high strength, and corrosion resistance in mild environments. It is magnetic in all conditions and can be heat-treated to achieve greater hardness.
- TP405: A ferritic grade that is often used for applications requiring resistance to high-temperature oxidation.
- TP409: Another ferritic grade, often used in exhaust systems and other applications requiring good corrosion resistance at high temperatures.
- TP430: A general-purpose ferritic stainless steel known for its corrosion resistance and durability.
- TP446: A high-chromium ferritic stainless steel with excellent resistance to high-temperature oxidation and corrosion.
- SUS 410L: A low-carbon version of the TP410 grade, designed for applications that require good ductility and corrosion resistance.
- UNS S44660: This is a high-chromium ferritic stainless steel with excellent corrosion resistance, often used in harsh environments.
