Alloy Steel 4330 MOD Distributor and Supplier
This alloy steel was developed as one of the nickel-chromium-molybdenum kinds which is medium carbon steel. It contains rather large sections of strength and is noted for its toughness. When it is supplied, it is typically hardened as well as tempered to achieve a high tensile range. In general, alloy steels were first patented in 1865 by Julius Baur, an American metallurgist. The steel was then produced at the Chrome Steel Co. in Brooklyn, New York. Chromium alloy was further developed for more popularity by Henri-Ami Brustlein, a French metallurgist, in subsequent years. Certain alloys have become increasingly popular as the aviation industry and even space exploration has increased the demand for materials capable of enduring the environments they are subjected to in such crafts. Commonly, many of these alloys are also utilized in other high-pressure, high-temperature, and chemically exposed applications. These other applications may include submarine or shipbuilding or even various vessels or nuclear industry related parts and components.
Chemistry of Alloy Steel 4340 MODThe chemistry of this alloy consists of Iron (Fe), Nickel (Ni), Chromium (Cr), Manganese (Mn), Carbon (C), Molybdenum (Mo), Silicon (Si), Sulfur (S), Phosphorus (P). There are also specifications to the percentage by weight of these elements such as Iron (95%), Nickel (1 to 2%), Chromium (less than 1%), Manganese (less than 1%), Carbon (less than 1%), Molybdenum (less than 1%), Silicon (less than 1%), Sulfur (less than 1%), Phosphorus (less than 1%). This 4340 alloy has a density of 7.85 g/cm3 (or 0.284 lb/in3). It has a Rockwell C hardness of 17, a 22% elongation at break, a shear modulus of 80 GPa (or 11600 ksi), and an elastic modulus of 190 to 210 GPa (or 27557 to 30458 ksi). This alloy also has a yield strength of 470 MPa (or 68200 psi) and ultimate tensile strength of 745 MPa (or 108000 psi). Its melting point is at 2600 degrees F and its Poisson's ratio is between 0.27 and 0.30. It has a 50% reduction in area as well. This alloy, therefore, demonstrates a wide variety of strengths that make it an ideal choice for a number of applications in various industries, but especially for plane parts and other elements critical in the aerospace field.
