Stainless Steel - 100 Not Out!100 years of Stainless Steel

2013 marks 100 years since stainless steel was discovered in Sheffield. The BSSA have selected 50 applications and features that demonstrate how stainless steel has influenced our lives so far.



Driving Down Pollution

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.
