Steel is an alloy of iron but with less carbon content, making it more durable and strong than original iron metal is. Bessemer figured out a way to smelt steel by reducing the amount of carbon in the iron ore. As countries worldwide began to construct this new kind of blast furnace, the steel industry soon skyrocketed. By the end of the 19th century, Britain produced over 30 million tonnes of this strong, desired alloy.
Steel is a widely used iron alloy due to its special properties. This type of steel mainly contains carbon and iron and only a minimal amount of other minerals.
There are three kinds of carbon steel, depending on how much carbon is in the metal. The three groups are called low carbon steel, medium carbon steel, and high carbon steel. Steel producers can harden and temper high carbon steels more than lower carbon content steels. These processes will increase the durability, strength, and resistance to the impact of the metal. This kind of steel has chemical elements like copper, chromium, nickel, and aluminum added to the metal.
These alloys will add specific properties to the steel that make it more valuable and useful to certain industries. Much like carbon steel, alloy steel has two different categories depending on the amount of alloys in the metal. The categories include low-alloy steels and high-alloy steels.
The primary alloy in stainless steel is chromium. The most valuable characteristic of stainless steel is its ability to resist corrosion. The metal will not rust or stain easily. The chromium in stainless steel acts as a barrier between the metal and outside chemical attack. Some of the main products that contain stainless steel are food equipment, medical equipment, cutting tools, and piping. The last common steel is tool steel. As the name suggests, manufacturers use this type of steel to make tools.
Tool steel has several different steels and alloys in it that contribute to its unique properties. Some main characteristics of tool steel are corrosion resistance, durability, hardness, and impact resistance. SK5 steel is Japanese carbon steel. The steel is usually low carbon or medium carbon steel, meaning it contains 0. Etude House Soon Jung 5.
