What is the difference between Stainless Steel Exhaust Manifold and ordinary steel exhaust manifold?

The main difference between stainless steel exhaust manifolds and ordinary steel exhaust manifolds is the composition and performance characteristics of the material.

Material corrosion resistance: The stainless steel exhaust manifold is made of stainless steel material, which has good corrosion resistance and can resist oxidation, corrosion and rust. Plain steel exhaust manifolds may require an additional anti-corrosion coating or painting to protect from corrosion.

High temperature resistance performance: Stainless steel exhaust manifolds usually have high temperature resistance performance, which can withstand high temperature exhaust air flow without deformation or failure. Ordinary steel exhaust manifolds may be easily deformed or damaged in high temperature environments.

Appearance and Finish: Stainless steel has a good appearance and usually does not require additional coating or painting because it has a certain polish and luster inherently. Whereas ordinary steel may require surface treatments to prevent rust and improve appearance.

Weight: Due to the lower density of stainless steel, stainless steel exhaust manifolds can be relatively lightweight, which helps reduce the weight of the entire exhaust system. Regular steel exhaust manifolds can be heavier.

Cost: Stainless steel is a relatively expensive material, so stainless steel exhaust manifolds tend to be more expensive than regular steel exhaust manifolds.

Performance stability: Stainless steel exhaust manifolds may maintain more stable performance over long-term use and are less susceptible to corrosion and thermal expansion. Common steel exhaust manifolds can suffer from corrosion, rust and performance degradation over time.

Exhaust Manifold

The product is welded by special-shaped stamping shell and steel pipe, and our company uses automatic robot welding. The material uses 409 stainless steel high temperature resistant material and imported three-way catalysis. Used for automotive engine exhaust filtration and emission; in line with US EPA and California ARB OBD II certification.
