In the U.S., the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its gauge. The larger the gauge number, the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Gauge differs between ferrous metals and nonferrous metals such as aluminum or copper. Copper ...
In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications. The number is in the following format: x.yyzz(zz)
The SAE steel grades system is a standard alloy numbering system (SAE J1086 – Numbering Metals and Alloys) for steel grades maintained by SAE International. In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels. These efforts were similar ...
Sverker 21 is a tool steel manufactured by Uddeholms AB. It is primarily used for Cold Work applications such as blanking, piercing, cropping, bending, forming and cutting. It's a proprietary equivalent to D2 [tool steel].

Between each step the diameter, or thickness, diminishes by 10.557%, and the area and weight diminish by ~ 20%. None of the above systems of measurement is part of the metric system . The current British Standard for metallic materials including wire is BS 6722 :1986, which is a solely metric standard, superseding 3737:1964, which used the SWG ...
A6, a grade of tool steel which air-hardens at a relatively low temperature (approximately the same temperature as oil-hardening grades) and is dimensionally stable. Therefore, it is commonly used for dies, forming tools, and gauges that do not require extreme wear resistance but do need high stability. [4] A7 [5] tool steel is an A7 type air ...
There are four types of materials available: O-1 tool steel, A-2 tool steel, A-6 tool steel, and 1018 steel (low-carbon or low-carb steel). Lengths are either 18 or 36 in (457 or 914 mm) long, various widths up to 16 in (406 mm) are available, and thicknesses range from 1 ⁄ 64 to 2.875 in (0.40 to 73.03 mm).
