types of steel pdf

Introduction To serve the increasing demands for more section types and to create the awareness on the proper use of steel, we have come up with a new product catalogue. Used in field houses, exhibition halls,. with span over 300' Most common type: three hinged arch; Lateral bracing; Diagonal bracing in curved surfaces between arches; Lateral bracing of ribs with purlins or trussed purlins. Alloying elements : chromium, nickel, molybdenum, vanadium, tungsten, cobalt, boron, copper and others. Steel is a malleable iron/carbon alloy containing from 0.10 to as much as 2% carbon, which determines the level to which it can be hardened. Although carbon steel is available in virtually all product forms, it is the Nickel chromium steel is has is a special type of steel which apart from being strong s also shock resistant therefore it is commonly used as an armor plate. Classification of Alloy steels 1. Low Carbon Steel - Also known as Mild Steel - Tensile strength of 555 N/mm - Hardness of 140 BHN - Bright fibrous structure - Tough , malleable , ductile and more elastic than wrought iron - Melting point 1410 8. High alloy steels (Having more than 5% alloying element) 13. There are over 3,500 different types of steel,which can be separated into four groups depending on its chemical content or metal alloy contents. Low Carbon Steel Plain carbon steels - very low content of alloying elements and small amounts of Mn. Carbon steels in which carbon represents 0.15–0.35%—those used most often as boiler and piping materials—are the focus of this Carbon Steel Handbook. The new 1 ENGINEERING HANDBOOK STEELMAKING Basic descriptions of making carbon, alloy, stainless, and tool steel p. 4. Such al-loys, which are based on type 304 (18-8) stainless steel, as shown in Fig. TESTING THE HARDNESS OF METALS Types … weldability, carbon steel is one of the most commonly used materials in the electric power generation industry. HEAT TREATMENT Quenching, hardening, and other thermal modifications p. 30. to improve the ease with which it can be hardened and other characteristics such as corrosion resistance. It is sometimes further alloyed with manganese, molybdenum, chromium, nickel, etc. Aluminum Steel. Alloy Steels Any steel other than carbon steel is called alloy steels. Continental Steel Pte Ltd assumes no responsibility for errors in or misinterpretation of the information contained in this handbook or in its use. METALS & ALLOYS Carbon grades, types, and numbering systems; glossary p. 13. Steel It is an alloy made from Iron and Carbon. Aluminum steel is smooth steel with a high content of aluminum. 12. They include these grades: • Iron-chromium-nickel grades corresponding to both standard AISI 300-series alloys and modified versions of these alloys. Because of its strong and smooth surface it is used in the making of furniture. Steel Arch Structures. largest stainless steel family in terms of alloys and usage. Steel Domes. 1, generally contain 16 to 26% Cr, 10 to 22% Ni, and CHEMICAL CONTENT Identification factors and composition standards p. 27. While there are many ways to categorize steel, we find it useful to break the types of steel down into four categories (C arbon, A lloy, S tainless and T ool Steel). Low alloy steels (Having 3 to 4% alloying element) 2.
