Driving Down Pollution

Motorway traffic Catalytic converter

Stainless Steel Catalytic Converter

The catalytic converter transforms harmful pollutants into less harmful emissions before leaving a vehicle's exhaust system - thereby reducing pollution on our roads.

Catalytic converter shells are made from stainless steel, typically grade 441 (1.4509). This is due to its excellent thermal fatigue properties (ability to withstand stress from the constant heating and cooling that is caused by the engine turning on and off again). Added to this, substances within the converter are usually highly corrosive and are active within a high temperature environment. This is another reason why stainless steel is used.

Stainless steel contributes towards helping our environment in many applications, reducing road pollution is just one example – sign up to the campaign to find out more.
