Sheet Metal Manufacturing: Mild Steel vs. Stainless Steel

Steel is one of the most common materials in the world and is used in various industries. From building construction to furniture making and more, steel is a material that is patronized for its strength and versatility. There are different categories and variants of steel depending on the qualities and characteristics they possess. In sheet metal manufacturing, two of the most commonly used types of steel are mild steel and stainless steel.

 

Mild Steel

Mild steel is a type of carbon steel with a low amount of carbon. In some places or industries, mild steel is also referred to as ‘plain carbon steel’ or ‘low carbon steel’. In general, the amount of carbon present in mild steel would be between 0.05% and 0.25% in weight. High carbon steel would generally contain 0.30% to 2.00%, while cast iron would have higher carbon content. Because of the low carbon content, mild steel is typically more ductile and machinable and easier to subject to laser cutting service.

However, because mild steel is not an alloy, it does not contain large amounts of other elements like chromium, molybdenum, and other alloying elements. The absence of such alloying elements means that the iron content in mild steel is prone to oxidation and rust. Thus, it is important that a protective coating be used to keep corrosion and rust at bay.

 

Stainless Steel

Compared to mild steel or plain carbon steel, stainless steel does not rust or corrode easily. At this point, it should be noted that stainless steel is prone to developing rust is not cared for properly. However, as the name suggests, it “stains less” than ordinary steel used in sheet metal manufacturing.

Because of its stainless quality and attractive finish, stainless steel is used a wide variety of applications. In the architecture industry for instance, stainless steel can be seen in building interiors in the form of handrails, countertops, and more. In the medical field, stainless steel is used for medical and surgical equipment such as scalpels, kidney dishes and others. Stainless steel is also used in a variety of industries including automotive, aviation, and even kitchen cutlery.
