Carbon Steel: Properties, Examples and Applications Types of Carbon Steel and Their Properties
Steel, alloy of iron and carbon in which the carbon content ranges up to 2 percent (with a higher carbon content, the material is defined as cast iron). By far the most widely used material for building the world’s infrastructure and industries, it is used to fabricate everything from sewing needles to oil tankers.
In essence, steel is composed of iron and carbon, although it is the amount of carbon, as well as the level of impurities and additional alloying elements that determine the properties of each steel grade. The carbon content in steel can range from 0.1% 1.5%, but the most widely used grades of steel contain only 0.1% 0.25% carbon.
Medium Carbon SteelComposition of 0.29% 0.54% carbon, with 0.60% 1.65% manganese. Medium carbon steel is ductile and strong, with long wearing properties. Medium carbon steel is ductile and strong, with long wearing properties.
Sep 28, 2017 · The minimum level of Carbon in Plain Carbon Steel and HSLA is 0.02%. Plain Carbon Steel grades go up to 0.95%, HSLA Steels to 0.13%. Manganese is present in all commercial steels as an addition and contributes significantly to steel’s strength and hardness in much the same manner but to a lesser degree than carbon.
Since most of the 1018 carbon steel is produced by cold drawing, this cold rolled steel is called C1018 (1018 cold rolled steel). AISI C1018 steel (1018 CRS) has good weldability, surface hardening quality, higher mechanical properties and better machinability.
Steels containing carbon as the major alloying element are called carbon steels. They may also contain up to 1.2% manganese and 0.4% silicon. Residual elements such as copper, molybdenum, aluminium, chromium and nickel are also present in these steels. AISI 1065 carbon steel is a high carbon steel, which has high tensile strength and heat treatable.
ASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them.
Carbon steels are alloys made from a combination of iron and carbon. By varying the percentage of carbon, it is possible to produce steel with a variety of different qualities. In general, the higher the carbon level the stronger and more brittle the steel. Low carbon steel is sometimes called "wrought iron."
Generally speaking, carbon steels contain up to 2% total alloying elements and can be subdivided into low carbon steels, medium carbon steels, high carbon steels, and ultrahigh carbon steels; each of these designations is discussed below.
As a group, carbon steels are by far the most frequently used steels. More than 85% of the steel produced and shipped in the United States is carbon steel. Low carbon steels contain up to 0.30% C. The largest category of this class of steel is flat rolled products (sheet or strip), usually in the cold rolled and annealed condition.
Low carbon steel also possesses good formability. This means that low carbon steel is easier to form into certain shapes, through such methods as pouring, molding and pressing. Also, low carbon steel is used for case hardened machine parts, chain, rivets, stampings, nails, wire and pipe.
ASTM A36 steel is one of the most widely used carbon structural steels, although the carbon content of A36 material is maximum 0.29%, it is considered to be the mild steel (content of carbon ≤ 0.25%).
Steel is made up of carbon and iron, with much more iron than carbon. In fact, at the most, steel can have about 2.1 percent carbon. Mild steel is one of the most commonly used construction materials. It is very strong and can be made from readily available natural materials. It is known as mild steel because of its relatively low carbon content.
Materials Medium Carbon Steel Bolts in SAE J429 (Grades 2, 5 and 8) SAE J429 is the standard specification for inch series steel bolts, screws, studs, SEMS screws and U bolts in sizes up to and including 1 1/2 inches. They are generally manufactured from variants of medium carbon steel.
As defined by the American Iron and Steel Institute, any steel is considered to be carbon steel when there is no specified minimum content for any other alloying element other than carbon. Carbon steels contain a carbon content between 0.05 and 3 percent, and trace amounts of other elements, such as manganese.
