2. 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 ...

3. 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.

4. Steel grades - Wikipedia

   en.wikipedia.org/wiki/Steel_grades

   Where x is the material type (only 1 is specified so far), yy is the steel group number (specified in EN10027-2) and zz(zz) is a sequential number designated by the certifying body, the number in brackets being unused but reserved for later use.

5. 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 ...

6. Tool steel - Wikipedia

   en.wikipedia.org/wiki/Tool_steel

   Steel of about 0.8% C gets as hard as steel with more carbon, but the free iron carbide particles in 1% or 1.25% carbon steel make it hold an edge better. However, the fine edge probably rusts off faster than it wears off, if it is used to cut acidic or salty materials.

7. 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]
