Applications and Uses of Stainless Steel in Automotive Industry

Did You Know? 
45 to 50% of automotive exhaust systems are made of stainless steel.
Probably, we all are aware of establishing uses of stainless steel in different industries as per their required proportions but at Automotives behind the scenes are quite different, as you read the fact – the ratio of stainless steel is quite higher than other applicants of stainless steel.
So, is it bad/good that Automotives have adopted stainless steel? And if yes, what characteristics of stainless steel made the automotive industry to adapt this higher ratio? Let’s get on to answering step-by-step, when it comes to automotive there are several requirements that need to be fulfilled including a lightweight yet safer experience, environmental-friendly, and affordability.
Now steel can also deliver those segments so why stainless steel and not just steel for automotive, forgot!? “RUST” can easily eat away the whole engine compartment, can weaken exhaust system mounts, and be able to create air leaks. 
Whereas stainless steel offers tremendous corrosion resistance, a wide yield strength range, and a lighter weight that apparently reduces vehicles’ weight and benefits in greater fuel efficiency and machinability rephrasing the whole thing into a reduced amount of CO2 emissions.
Thus, after these long checkmarks of benefits, stainless steel offers an environmentally-friendly approach too. Things are turning informative, then why not dig into some more of it? Come let’s do it together.
Role of Stainless Steel Used in Automotive Industry
Since the 1930s, the average count of 15 to 22 kilos of stainless steel gets used in a single car which was mainly found in the exhaust system and sundry small parts. 
In today’s date uses of stainless steel in automotive are also extended to other automotive applications such as fasteners, springs, and tubing, as well as brackets, flanges, substructures, and panels.
At younger ages, the cost of wielding was more expensive than now as the years passed by – stainless steel types such as austenitic, martensitic, ferritic, and many other stainless steels were discovered.
From all these stainless steel categories austenitic stainless steel became ideal to use for the automotive industry due to its easy welding and long durability.
{Additional Information on Exhaust Systems: Where we saw the central importance of stainless steel in exhaust systems, we might forget the role of its valves that perform opening and closing operation that controls the gas flow and optimize the engine-back pressure enabling exhaust systems to provide improved performance and auditory control.
These exhaust valves get manufactured from bright bars – in different shapes such as square, round, or hex and with particular grades as per the requirement.}
