Is stainless steel better than carbon steel?
Steel is found in all kinds of products, from the aerospace industry to kitchen utensils. Such applications require a versatile material and the steel fits perfectly. Did you know that the word steel actually describes a complete family of metal alloys? Some of the most important iron alloys are stainless steel and carbon steel.
In the next article, we will talk about them and tell you what is your best option according to your needs.
Steel composition
Iron and carbon are constituents of steel. In general, steels with a higher carbon content are hard and fragile, while those with a lower content are ductile and resistant.
Simply put, the carbon composition in steel is not constant and varies depending on the type and degree to be achieved. For example, the carbon content of 0.2% to 1.2% by weight is common in this metal.
What makes stainless steel unique is its impeccable corrosion resistance, or in other words, the ability not to corrode or oxidize under normal circumstances.
The difference between stainless steel and carbon steel lies in the amount of chromium in the composition. The presence of chromium (between 10.5% to 11%) reacts with oxygen and causes the formation of a passive layer on the surface of stainless steel. This inert layer is what gives rise to the corrosion resistance of stainless steel.
Because chromium is not present in carbon steel, its corrosion resistance is not as good as that of stainless steel. Only this feature disqualifies carbon steel as a valuable candidate for various applications where stainless steel is used.
In summary, stainless steel offers a massive improvement in strength, hardness and, most importantly, in corrosion resistance.
When it comes to choosing a material for construction, cars, machinery and even surgical tools, stainless steel is approved above carbon steel. This is because the greater corrosion resistance of stainless steel allows it to be more durable than carbon steel.
If duration and corrosion resistance are key criteria for choice, then stainless steel is without a doubt your best option.
