AISI Steel Grades American Iron & Steel Institute. AISI steel grades are usually a four digit number where the first two digits indicate the alloy and the second two the the carbon content. For example 10xx are plain carbon steel, 41xx Chromium Molybdenum Steel and 43xx Nickel Chromium Molybdenum Steel.

Mar 23, 2015 · The most commonly used grades of Alloy Bar:Grade 4140 Chromium Molybdenum Steel. Grade 4340 Nickel-Chromium-Molybdenum Steel. Grade 6150 Chromium Vanadium Steel. Grade 8620 HSLA -Nickel-Chromium-Molybdenum Steel. Buy Alloy Steel. This article is the second in a four-part series on the different types of steel. Alloy Steel:Properties, Processing and Applications Alloy steel is a class of steel that, in addition to carbon, is alloyed with other elements, ranging from 1 wt.% to 50 wt.%, which are used to enhance the materials various properties .. These elements commonly include manganese, nickel, chromium, molybdenum, vanadium, silicon, and boron. Less common elements include aluminium, cobalt, copper, cerium, niobium, titanium, tungsten, tin Difference Between Alloy Steel and Stainless Steel Alloy steel can be classified into two main types, i.e., high strength low alloy steel, which has less than 8% of alloying elements in the composition, and high alloy steel, which has more than 8% of alloying elements in the mix.
The roster of stainless steel classifications is vast. Fortunately, this metal is easily distinguished from the others, because three-digit numbers are used instead of four. Most fall in Nickel Alloys Nickel InstituteThe best-known is alloy 800 (UNS N08800) and its variants 800H (UNS N08810) and 800HT (UNS N08811). (Recently, these alloys were classified as stainless steels reflecting their high Fe content) Ni Cr Fe (with Mo and Cu) alloys with excellent corrosion resistance in specific applications. Property Information for Steel AlloysYou can find typical values such as tensile strength, density, and thermal conductivity for steel alloys under the name Steels, General Properties. If you know the alloy number in which you are interested (i.e. 1020 Steel or DIN 1.0402), type it in the search box
The figure below shows the TTT diagram for a 4340 steel alloy. The numbers tell us about the composition of the steel. The '43' refers to alloy composition. 165 - 200 wt% Ni, 0.4-0.9 wt% Cr, 0.2-0.3 wt% Mo. The '40' refers to the carbon concentration, which is 0.40 wt% Stainless Steel What Do All The Numbers Mean? SteelmorMost steel sheet, plate, bar, tube, pipe, and structural products are made from 300 series alloys. Sometimes youll see 18/0 stainless steel, meaning there is 18% chromium but no nickel. This metal falls into the 400 series, and is commonly called 430 stainless steel. 400 series alloys lack the corrosion resistance of those in the 300 series Stainless Steel Grades - Continental Steel & Tube CompanyStainless Steel Alloy 254; Stainless Steel Alloy 347H; Stainless Steel Alloy 904L; Stainless Steel Alloy Zeron® 100, Super Duplex Stainless , Super Duplex; Stainless Steel Alloy 17-4 PH, UNS S17400; Stainless Steel Alloy 255, Ferralium® Alloy 255; Stainless Steel Alloy 309S; Stainless Steel Alloy 304-H; Stainless Steel Alloy 410S; Stainless Steel Alloy 321H

Unified Numbering System (UNS) for Metals and AlloysThe numbers assigned must integrate numbers from existing numbering systems whenever possible so as to enable easy recognition. The numbering system must be designed to adapt current metals and alloys, and to anticipate the need to furnish numbers for new alloys for the future.
