What material is commonly used to manufacture muffler shrouds in exhaust systems?

Stainless steel is commonly used to manufacture muffler shrouds in exhaust systems due to its ability to withstand high temperatures and resist corrosion. Exhaust systems operate under extreme conditions, where exposure to hot exhaust gases can lead to rapid deterioration of materials. Stainless steel provides the necessary strength to handle these harsh environments while also being durable enough to resist rust and corrosion caused by moisture and other environmental factors. Its overall longevity and performance in high-heat applications make it the preferred choice for muffler shrouds in many automotive and aviation applications, ensuring reliable operation over time.

Other materials, while they may have their own uses, do not offer the same combination of heat resistance and durability that stainless steel provides. Aluminum, for example, is lighter but can be less durable under extreme heat conditions. Cast iron is strong but heavy and prone to rusting. Plastic might be lighter and less expensive, but it wouldn't hold up under the elevated temperatures and could degrade quicker than metal alternatives.
