Welded stainless steel tubes for automotive applications

CSM TUBE stainless steel tubes are designed to meet the demanding requirements of the automotive industry, ensuring safety, durability, and an excellent cost-performance ratio.

Dimensions and materials

• Diameters: from 5.00 mm to 32.00 mm
• Wall thicknesses: from 0.30 mm to 2.11 mm
• Ferritic grades: 400 series (e.g. 409, 441)
• Austenitic grades: 300 series (e.g. 304, 304L, 316L)

CSM TUBE manufactures tubes for a wide range of critical automotive applications, including:

• EGR and DPF systems: tubes resistant to thermal cycling and exhaust gas corrosion.
• Glow plugs: components for combustion chamber pre-heating in diesel engines, requiring very tight tolerances.
• Fuel lines: precision tubes used in automotive fuel systems.

Materials and technical specifications

For the automotive sector, the most suitable alloys are selected according to the specific application requirements:

• Ferritic steels (400 series): such as 409 or 441, chosen for their mechanical strength and stability under thermal cycles.
• Austenitic steels (300 series): such as 304L or 316L, for components requiring maximum corrosion resistance and ductility, allowing demanding forming operations such as hydroforming.

Product quality and safety

Each component undergoes rigorous internal and external inspections. In addition to non-destructive eddy current testing for leak tightness, automotive tubes can be subject to burst tests with internal pressures up to 1000 bar. Fully digitalized data management and in-line marking ensure complete traceability, which is essential to meet the high supply standards of the global automotive industry.

Thanks to its long-standing expertise and continuous technological investments, CSM TUBE has established direct relationships with leading manufacturers, who rely on the dimensional precision and reliability of its products.
