2. SAE steel grades - Wikipedia

   en.wikipedia.org/wiki/SAE_steel_grades

   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 ...

4. High-strength low-alloy steel - Wikipedia

   en.wikipedia.org/wiki/High-strength_low-alloy_steel

   High-strength low-alloy steel (HSLA) is a type of alloy steel that provides better mechanical properties or greater resistance to corrosion than carbon steel. HSLA steels vary from other steels in that they are not made to meet a specific chemical composition but rather specific mechanical properties.

5. Alloy steel - Wikipedia

   en.wikipedia.org/wiki/Alloy_steel

   Researches created an alloy with the strength of steel and the lightness of titanium alloy. It combined iron, aluminum, carbon, manganese, and nickel. The other ingredient was uniformly distributed nanometer-sized B2 intermetallic (two metals with equal numbers of atoms) particles. The use of nickel team avoided problems with earlier attempts ...

6. Low-alloy special purpose steel - Wikipedia

   en.wikipedia.org/.../Low-alloy_special_purpose_steel

   Low-alloy special purpose steel is a grade of tool steel characterized by its proportion of iron to other elements, the kind of elements in its composition, and its treatment during the manufacturing process. The three ASTM established grades of low-alloy special purpose steel are L2, L3, and L6. [1]

7. Unified numbering system - Wikipedia

   en.wikipedia.org/wiki/Unified_numbering_system

   The Unified Numbering System for Metals and Alloys (UNS) is an alloy designation system widely accepted in North America. Each UNS number relates to a specific metal or alloy and defines its specific chemical composition , or in some cases a specific mechanical or physical property .
