Choosing the right metal for the job is rarely simple. You need to compare each type's strength, weight, and cost to figure out how well they fit your needs... and once you've finally settled on a choice, you still need to navigate through the various variants and grades available!
If you've decided to go with steel for your project, you might find yourself stuck choosing between mild steel and stainless steel. Both are commonly used in a wide range of industries, including transport, automation, and manufacturing, but they differ massively in terms of strength and workability.
Clickmetal have delivered custom-cut mild steel and stainless steel for projects of all shapes and sizes. Below, we'll break down what exactly mild steel and stainless steel are, explore whether mild steel is the stronger option, and guide you in choosing the right type for your project.
Also known as carbon steel, mild steel is mainly made up of iron and carbon. It typically contains a low percentage of carbon (up to 0.3%) and small amounts of other elements like manganese, sulphur, and phosphorus. Mild steel is ductile and malleable, making it easy to shape and form; however, it's prone to rusting when exposed to moisture and air.
Stainless steel, meanwhile, is an alloy composed of iron, chromium, nickel, and other elements. The chromium (usually at least 10.5%) is what gives stainless steel its unique corrosion resistance, while the nickel and other elements improve its overall strength and durability.
In terms of raw strength, stainless steel generally comes out on top of mild steel. This is mainly because of the presence of chromium.
The chromium in stainless steel reacts with oxygen, forming a thin, protective layer of chromium oxide on the surface. This layer acts like a shield, safeguarding the underlying metal from further oxidation and helping maintain the integrity of the crystal structure. This allows the metal to endure higher pulling and crushing forces before giving way.
The presence of chromium also affects the crystal structure of stainless steel. Unlike mild steel, which has an iron-carbon crystal structure, stainless steel has a face-centred cubic (FCC) structure. This tightly packed arrangement of atoms provides better resistance to deformation and the dislocation of atomic planes, contributing to an overall improvement in strength.
However, that doesn't mean mild steel should be discounted entirely. Despite not being as strong and corrosion-resistant as stainless steel, its simpler composition gives it greater ductility and malleability. This makes mild steel a preferred choice in construction, automotive, and other applications where workability and cost-effectiveness outweighs the need for strength and corrosion resistance.
Choosing between mild steel and stainless steel for your project depends on a few key factors:
Keep in mind that both mild steel and stainless steel come in many different grades. Each grade has different properties, so be careful to choose the right one for your application.
