BIS Indian Standards For Designation Of Steels Designation of Plain carbon steels. These are denoted like x, C, y. Where, x Number 100 times the average percent of carbon. y Number 100 times the average percent of Manganese. Example:30C8. Where, 30 = 100 times average % of Manganese. 8 = 100 times average % of Carbon. Average % of Carbon = 30/100 = 0.3%. Average % of Manganese = 8/100 = 0.08%
This article addresses classifications and designations for carbon steels and low-alloy steels, particularly high-strength low-alloy (HSLA) steels, based on chemical composition, manufacturing methods, finishing method, product form, deoxidation practice, microstructure, required strength level, heat treatment and quality descriptors.
Designation of Carbon and Low-Alloy Steels - Steel
SAE-AISI DesignationsAMS DesignationEuropean and Japanese Designation SystemsThe SAE-AISI system is applied to semi-finished forgings, hot-rolled and cold-finished bars, wire rod and seamless tubular goods, structural shapes, plates, sheet, strip, and welded tubing. Carbon steelscontain less than 1.65% Mn, 0.60% Si, and 0.60% Cu; they comprise the lxxx groups in the SAE-AISI system and are subdivided into four distinct series as a result of the difference in certain fundamental properties among them. Designations for merchant quality steels include the prefix M. A carbon steel designatiSAE/AISI Carbon Steel Naming Conventions

Engineering Materials and How They Are designated.Designation of SteelsDesignation of Steel Castings and ForgingsSome Examples Asked in ExaminationIntroduction to the SAE-AISI Designation System ::Total 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.
Fundamentals of the Heat Treating of Steelcarbon steel and low-alloy steel, the maximum carbon is about 2.0%; in high-alloy steel, about 2.5%. The dividing line between low-alloy and high-alloy steels is generally regarded as being at about 5% metallic al-loying elements (Ref 1). Fundamentally, all steels are mixtures, or more properly, alloys of iron and carbon.

Steel grades:cross-reference of designation standards Jun 17, 2019 · AISI uses a basic four-digit system to show the chemical composition of carbon and alloy steels. The first digit indicates the main alloying element, The second digit of the series indicates the top grade element, and The last two digits of the series indicate the carbon concentration in percentage.
Jul 19, 2018 · AISI standards is one of the most popular methods of designation in the field of stainless steel (American Iron and Steel Institute). The latter is is an association of North American steel producers. In our todays post we want to learn more about this designation system that allows the identification of types of steel. Carbon steel Designation of Carbon Steels - TubewebAISI/SAE Carbon Steels First two digits indicate grade of carbon steel. Last two digits represent middle of carbon range. If carbon over 1.00%, a third digit is added.
