Alloy steels are made by combining carbon steel with one or several alloying elements, such as manganese, silicon, nickel, titanium, copper, chromium and aluminium. Figure 13.11, shows the capabilities of the ANSI group which includes ASTM A217 WC9 which has 2.25% chrome. Steel alloys can be found anywhere from buildings to bridges to ships to home appliances. Cast iron is iron mixed with other metals. This creates an alloy which has specific properties that are not found in carbon steel. Stainless Steel 4.Tool Steel. D Can be heat treated - austenitizing, quenching and then tempering. Free cutting steel or Free machining steel Reply. Steel classification is important in understanding what types are used in certain applications and which are used for others. Alloy Steel; Stainless Steel; Tool Steel; There are many different grades of steel that encompass varied properties. An alloy is a combination of metals or metals combined with one or more other elements.For example, combining the metallic elements gold and copper produces red gold, gold and silver becomes white gold, and silver combined with copper produces sterling silver.Elemental iron, combined with non-metallic carbon or silicon, produces alloys called steel or silicon steel. Academia.edu is a platform for academics to share research papers. January 6, 2019 at 6:06 pm. Stainless steel is defined as alloy steel containing, by weight, 1.2% or less of carbon and 10.5% or more of chromium, with or without other elements. Standard Metal Numbers, Codes, Classifications and Designations (Updated June 2020) The system used for metal numbers that classifying metals and their alloys is found in specifications and drawings.
Read more about the classification of carbon steel by following the link below. Classification of Steel By Use and Application. There are several alloys of various metals, such as alloys of Aluminium, Potassium, Iron, Cobalt, Nickel, Copper, Gallium, Silver, Tin, Gold, Mercury, Lead, Bismuth, Zirconium, and rare earth.

Most alloy steels in use fall under the category of low alloy Alloy steels are, in general, with elements as: > 1.65%Mn, > 0.60% Si, or >0.60% Cu. Steel framing classifications mostly come from ASTM.
Alloy Steel 3. it is highly readable. AISI - SAE CLASSIFICATION SYSTEM AISI XXXX American Iron and Steel Institute (AISI) classifies alloys by chemistry 4 digit number 1st number is the major alloying element 2nd number designates the subgroup alloying element OR the relative percent of primary alloying element.
