Mild Steel Vs Stainless Steel
There are different types of steels, and it is understandable that there is a lot of confusion about each of its features. Mild steel and stainless steel are two of the most common grades of steel that can be distinguished on certain characteristics.
Price Difference Between Stainless Steel And Mild Steel
The price of ms is cheaper in comparison to stainless steels. ss is costly due to the polish and finish required to produce the grade. However, in the long run, maintaining a mild steels costs higher than the latter.
Weight Difference Between Stainless Steel And Mild Steel
The weight of ss and mild steels is nearly identical. Mild steels weighs slightly less than that stainless steels. This is due to the hardening properties of stainless steels, as it occupies more weight and is difficult to handle.
Is Stainless Steel Harder To Cut Than Mild Steel
Stainless steels is generally brittle, making them difficult to twist and cut than mild steel. When stainless steels has a higher impact force, the metal tends to break rather than be cut. The lower carbon content in ms allows them to have higher ductility enabling them to be cut easily.
Electrical Conductivity Of Stainless Steel Vs Mild Steel
Advantages & disadvantages of Mild Steel
Mild steels has lower levels of carbon that is highly malleable and can be easily bent, cut, and twisted to create the desired shape. This allows them to be used in manufacturing different structural applications. The mild steels grade is also considerably lighter reducing the weight in different applications. Furthermore, they are greatly affordable and have good magnetic properties.
The major disadvantage of mild steels is that it is comparatively less strong, making them a bad choice in different structural applications. The steels also cannot be heat-treated as the carbon content will be affected. This is why this metal is a poor choice for heat treatment procedures.
Where to use Mild Steel instead of Stainless Steel
MS is designed possessing superior ductility, allowing it to be easily bent, cut, and shaped, which is difficult with stainless steel. This steels is commonly used in construction industries that use low-duty pipes that are available at affordable prices. MS grades are also useful in manufacturing bolts, sheet piles, railway tracks, channels, rolled sections, and other equipment that are difficult to shape using stainless steel.
Why stainless steel better than mild steel?
Stainless steels is designed by adding iron and carbon with other constituting alloys that help harden the material. This steels has enhanced strength as compared to stainless steel. They work well in corrosive setups and are efficient across high temperature conditions. The aesthetical appeal of stainless steels makes them a choice for different industries. Apart from this, the cleanliness and maintenance of this steels is simple. They are durable and work for long periods in treacherous conditions.

Mild Steel Vs Stainless Steel Weight
Mild steels is heavier than stainless steels. SS density is not massive enough, but it is still stronger.
MS is very reactive and will readily revert back to iron oxide (rust) in the presence of oxygen, water and ions. The readiness of steels to oxidize on exterior exposure means that it must be adequately protected from the elements in order to exceed and meet its design life.
Construction – MS is used extensively for construction, as it advantageous machinability and weldability. It can withstand impact loads and is broadly used in like buildings, construction and bridges.
Machinery applications – like automobile manufacturing. It is readily accessible to cutting and welding.
Knives – MS knives stay sharper for a easier to sharpen and longer time. Professional chefs have a preference for high ms knives as they required a lot of precision knife work in the kitchen.
Fencing- MS can be adept into different shapes and provides a visual appeal.
wire, Poles, Pipelines, and nails are commonly manufactured by using mild steels
