Steel classification according to EN 10027-2.Free searchable database "European steel and alloy grades" Comparison of various steel standards Archived 2019-04-27 at the Wayback Machine; Comparison of various tool steel standards; General guide to the EN 10027 steel name and numbering systems.
In 2008, 2009, 2015 and 2016 output fell in the majority of steel-producing countries as a result of the global recession. In 2010 and 2017, it started to rise again. Crude steel production contracted in all regions in 2019 except in Asia and the Middle East. India is the 2nd leading producer of iron and steel industries. [citation needed]
Rio Tinto has said it will cancel contracts and sell the steel on the spot markets if Chinese steel mills back down on the new quarterly pricing regime. [ 16 ] In 2011 China was the largest producer of steel in the world producing 45% of the world's steel, 683 million tons, an increase of 9% from 2010. 6 of 10 of largest steel producers in the ...
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 ...
A UNS-derived system known as ISC (in Chinese 统一数字代号, literally "unified numeric designator") is used in China in parallel to the composition-based nomenclature. [6] Individual grades may receive the same number (e.g. S31603), a slightly different number (e.g. S30400/S30408, S17400/S17440), or a totally different one (e.g. S20200 ...

Tool steel is any of various carbon steels and alloy steels that are particularly well-suited to be made into tools and tooling, including cutting tools, dies, hand tools, knives, and others. Their suitability comes from their distinctive hardness , resistance to abrasion and deformation, and their ability to hold a cutting edge at elevated ...
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.
