Iron and carbon are two of steel’s primary constituents. Steels that contain more carbon tend to be harder and more brittle, whereas steels that contain less carbon tend to be ductile and tougher. Of course, things are rarely that easy. To boost corrosion resistance, alloying elements such as chromium, molybdenum, nickel, manganese, or silicon can be added.
Stainless Steel Characteristics
Iron, carbon, and at least 10.5 percent chromium are all present in stainless steel. The crucial component is chromium, which combines with oxygen to form a passive layer that shields the steel from corrosion. This layer lowers the possibility of stainless steel rusting, which is crucial for exterior site furnishings like bollards deployed in moist areas.
The ability to resist corrosion improves with increasing chromium concentration. When buying appliances and other expensive things, it’s crucial to consider the stainless steel grade. Steels are not all made equal. The difference between stainless steel with a least 10.5 percent chromium content and one with a minimum of 16 percent chromium content can be seen in maintenance costs and service life.
Carbon Steel Characteristics
Iron and 0.12 to 2.00 percent carbon are the main ingredients in carbon steel. The larger definition encompasses alloy steels, which can also have an alloy percentage of up to 10.5%. There is a significant range in physical properties, particularly hardness, even within the constraints of less than two percentage points of carbon.
Due to extreme hardness, high carbon steels are excellent at resisting abrasion and maintaining shape. It can bear a lot of pressure before breaking. High carbon steels are more likely to break than bend when subjected to extremely high tensile stress, which is unfortunate because hard metals are also fragile.
Because they are easier to use in manufacturing, more ductile and have lower production costs than high carbon steels, low carbon steels are more widely used. Due to their tendency to bend rather than break under stress, low-carbon steels are ductile and simple to process and weld. Carbon steel products are frequently utilized in seamless tubes, steel plates, bolts, fittings, and auto body panels.
