WF Mandrel Bent Exhaust 90° Bend - 5" (127mm) Mild Steel

Premium Mandrel Bent Exhaust Components

This 5" (127mm) outer diameter mandrel-bent 90° exhaust bend delivers professional-grade performance for custom exhaust fabrication and repair. Precision-formed using mandrel bending technology, this bend maintains consistent wall thickness and internal diameter throughout the curve, ensuring optimal exhaust flow without restriction.

Constructed from 1.6mm mild steel, this exhaust bend offers the ideal balance of strength, flexibility, and weldability for exhaust system applications. The material properties make it perfect for both professional fabricators and DIY enthusiasts working on custom exhaust builds, repairs, or performance upgrades.

• Flexible & Ductile: Less brittle than high-carbon steel, easier to work with
• Professional Grade: Suitable for automotive, motorcycle, and industrial exhaust applications

Technical Specifications:

• Outer Diameter: 5" (127mm)
• Wall Thickness: 1.6mm
• Bend Angle: 90 degrees
• Material: Mild steel (low-carbon steel)
• Carbon Content: Approximately 0.05-0.25%
• Part Number: SB90 50000 / M9211

Why Mild Steel for Exhaust Systems? Mild steel is the preferred material for exhaust fabrication due to its excellent combination of properties. With low carbon content, it remains malleable and ductile, making it easier to form, cut, and weld compared to high-carbon alternatives. This flexibility is essential for custom exhaust work where precise fitment and reliable joints are critical. The material is also less prone to cracking during welding and thermal cycling, ensuring long-lasting exhaust system integrity.

Applications:

• Custom exhaust system fabrication
• Exhaust repair and replacement
• Performance exhaust upgrades
• Automotive and motorcycle exhaust builds
• Industrial exhaust routing
• Turbo and manifold installations
