For Numbering System. There is a UNS designation for each steel some steels, it may be easier to use the AISI/SAE system, for composition, and it consists of a letter followed by five digits. The others, the ASTM system. We first examine the way the steels are system fully incorporates the AISI/SAE system. 17-7PH Stainless Steel:An Introduction to this Workhorse In the 1930s and 40s, a standardized numbering system for the different stainless steel grades was developed by the American Iron and Steel Institute (AISI) and SAE to categorize the various stainless steel types. The AISI/SAE stainless steel numbering system is as follows:200 series -
French (AFNOR) standards for steel materials Introduction to the Unified Numbering System of Ferrous Metals and Alloys #AISI The American Iron and Steel Institute has established a designation system for structural shapes, which has been adopted by steel producers. AISI/SAE steel classification System SHEW-E STEELJul 25, 2018 · AISI / SAE 4330 indicates a Ni-Cr-Mo alloy steel containing 1.82% Ni , 0.50-0.80% Cr and 0.25% Mo, AISI 4330V is a modification of the 4330 alloy steel grade, with hardenability and other characteristics improved by the addition of vanadium.

Chemical compositions of AISI (ASTM/ASME) and UNS Chemical compositions of AISI (ASTM/ASME) and UNS austenitic stainless steel grades Introduction AISI ASTM ASME and UNS. Most ASTM and ASME standards list the steel grades by their UNS (Unified Numbering system) numbers, but also make reference, where appropriate, to the more general AISI, (American Iron and Steel Institute), grade designations.
The SAE/AISI system classifies all other alloy steel using the same four digit index as follows:2 - Nickel steels; 3 - Nickel-chromium steels; 4 - Molybdenum steels; 5 - Chromium steels; 6 - Chromium-vanadium steels; 7 - Tungsten-chromium steels; 9 - Silicon-manganese steels. In general way for steel Metals & Alloys in the Unified Numbering System, 13th EditionMay 09, 2017 · The Unified Numbering System for Metals and Alloys (UNS) provides a means of correlating many internationally used metal and alloy numbering systems administered by societies, trade associations, and individual users and producers of metals and alloys. Jointly developed by SAE International and the American Society for Testing and Materials (ASTM), it provides the uniformity Steel Identification Charts PearltreesIntroduction to the SAE-AISI Designation System. The SAE system uses a basic four-digit system to designate the chemical composition of carbon and alloy steels. The first digit (1), of this designation indicates a carbon steel; i.e., carbon steels comprise 1xxx groups in the SAE-AISI system and are subdivided into four categories due to the variance in certain fundamental properties among them.
- IntroductionDevelopment of The Unified Numbering SystemGuidelines For System FormationSummary of The SystemImportance and Use of The UnsThe traditional designation systems for metals and alloys in the United States have been developed by a large group comprising trade associations (Aluminum Association (AA), the American Iron and Steel Institute (AISI), and the Copper Development Association (CDA)), metal producers, professional societies (ASTM International, the American Welding Society (AWS), and the Society of Automotive Engineers (SAE)), and the U.S. government. In the 1960s the traditional system was found to have some problemMetals Bundle - SAE TrainingThis class also discusses how refractory metals and how nonferrous metals are classified in the Unified Numbering System (UNS). Classification of Steel This course introduces you to steel designations systems, particularly AISI-SAE and UNS methods, and describes classifications for plain carbon, alloy, high-strength low alloy, stainless, and tool steels, with a focus on AISI-SAE designations.
