However, it is hard to categorize each and one of them. Therefore, in this article, we will introduce two main types of steel: Alloy steel and carbon steel. Carbon steel is iron with carbon added (including a trace of other elements), while alloy steel also includes other elements.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Alloy Steel:<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Alloy steels have a high percentage of other elements apart from iron and carbon. Other elements, such as manganese, silicon, nickel, titanium, copper, and chromium, are also called alloy elements because they form an alloy. Alloy elements are added to improve the hardness and durability of the steel. Also, it improves corrosion resistance due to the high amount of other elements like chromium. Depending on each component\u2019s proportion, alloy steel\u2019s property changes.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Commonly, alloy steel has comparatively low strength, high weldability, high melting points, high ductility, and high corrosion resistance.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In addition, there are common alloy elements and traits:\u00a0<\/span><\/p>\n<h4><span style=\"font-weight: 400;\">&#8211;<\/span><span style=\"font-weight: 400;\"> \u00a0 \u00a0 \u00a0 <\/span><span style=\"font-weight: 400;\">Manganese:<\/span><\/h4>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Added to fine-tune the heat-treating requirements.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Requires fast quench from high temperature to a very low temperature to harden. However, fast quench has a high risk of cracking.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Slower cooling rate. It can be quenched in warm oil, water, room-temperature air. Example of air quenching steel: A4 tool steel, which has 1.8% to 2.2% manganese.<\/span><\/li>\n<\/ul>\n<h4><span style=\"font-weight: 400;\">&#8211;<\/span><span style=\"font-weight: 400;\"> \u00a0 \u00a0 \u00a0 <\/span><span style=\"font-weight: 400;\">Chromium:<\/span><\/h4>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Over 11% chromium, you get stainless steel, which reduces corrosion dramatically.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Dramatically affects strength, hardness, and heat treatment.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Combination of cobalt and chromium gives very high wear resistance.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Commonly used for cutting dies, forming, tire shearing blades, and punches.<\/span><\/li>\n<\/ul>\n<h4><span style=\"font-weight: 400;\">&#8211;<\/span><span style=\"font-weight: 400;\"> \u00a0 \u00a0 \u00a0 <\/span><span style=\"font-weight: 400;\">Molybdenum:<\/span><\/h4>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Increase corrosion resistance. Works with manganese to lower the required quench rate.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Increase toughness and tensile strength. Heavy load application.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">4140 Steel is the most common of molybdenum and chromium combinations. Also referred to as Chromoly steel.<\/span><\/li>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Applied in heavy gears, large shafts, workhorse of the steel world.<\/span><\/li>\n<\/ul>\n<h4><span style=\"font-weight: 400;\">&#8211;<\/span><span style=\"font-weight: 400;\"> \u00a0 \u00a0 \u00a0 <\/span><span style=\"font-weight: 400;\">Vanadium:<\/span><\/h4>\n<ul>\n<li style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">During the heat treating, it helps to control the grain size of the metal.

Other small amounts of elements include silicon, manganese, sulfur, and phosphorous. Commonly, carbon steel has high strength, low weldability, low melting points, low ductility, and low corrosion resistance.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Carbon steel is also divided into high carbon steel, medium carbon steel, and low carbon steel. However, unlike alloy steel, this is the main distinction between carbon steel types.
