Silencing Unit Stainless Steel Honeycomb for Automotive Exhausting Tube
Silencing Unit Stainless Steel Honeycomb for Automotive Exhausting Tube is multiple corrugated stainless-steel sheets welded as per to accurate pre-determined cell size while the corrugating is processed on a gear press with the sheets delivery from a roller of rolled stainless-steel.
High temperature and corrosion exhaust should be with a high performance exhaust pipe on silencing. This is the most suitable application.

Welded honeycomb core, no matter what material is, such as aluminum, stainless steel, steel, titanium etc, possesses better mechanical properties against regularly produced glued honeycomb core. So it performs significantly better again the common honeycomb bonded by adhesive on strength, modulus, corrosion resistance, dimensional stability etc. However, generally, these critical performance variables should be evaluated: material, airflow and attenuation.
1. Material Composition
Stainless steel grade should be considered according to the real application. Custom materials other than stainless steel are available upon request. Here are the parameters need to be evaluated:
Material type and grade is the first aspect to be evaluated then plating, discussed in depth later, can improve durability.
Material, structure and thickness of the material can affect the total part weight.
2. Corrosion resistance
Typically brass and stainless steel should be used in slashing environments. Plating or nonconductive surface coatings can improve corrosion resistance for all honeycomb types.
3. Airflow & Attenuation
Airflow and attenuation are inversely proportional. Infinitely large honeycomb cells result in infinitely small attenuation (and vice versa). Typically, as a design baseline, airflow performance requirements are calculated to meet thermal performance needs for the assembly that the vent is to be installed onto. Once airflow is determined, attenuation and other requirements can be evaluated. Standard cell sizes for honeycomb are 1/16", 1/8" and 1/4", with 1/8" being most common. Standard thicknesses are 1/4," 1/2" and 1," with 1/4" being most common.
