Knowing the difference between mild steel and stainless steel is key to picking the right type for your project. Both types are used in manufacturing, fabrication and construction, but each has distinct properties which make them more suited to different applications.
Stainless steel
In 1913, Harry Brearley from Sheffield created what is purported to be the world’s first ever stainless steel. Made primarily from iron and chromium, this corrosion-resistant alloy has to contain 10.5% chromium as a minimum to provide a protective layer of chromium oxide.
Mild steel
Mild steel has a low carbon content, making it much easier to work with and the reason why it is so widely used in manufacturing and construction industries in particular.
Differences
The main difference between stainless and mild steel is their chemical composition, which alters the hardness, strength and ductility. Mild steel is primarily made of iron and carbon, but stainless steel is a combination of carbon, iron, chromium and other alloys. If you require advice on which sort of steel is best for your project, consult a sheet metal fabrication company such as dkmsheetmetal.co.uk/.
Mild steel is commonly used for structures like bridges or in commercial buildings, because it is more malleable and less likely to crack than stainless steel. It is highly versatile, which means it is used in numerous industries, including household appliances manufacturing industry and in transportation.
In industries where hygiene is important, such as the food and beverage or medical and healthcare sectors, stainless steel’s corrosion resistance makes it ideal.
