  3. ASTM A992 - Wikipedia

    en.wikipedia.org/wiki/ASTM_A992

    ASTM A992 steel is a structural steel alloy often used in the US for steel wide-flange and I beams. Like other carbon steels, the density of ASTM A992 steel is approximately 7850 kg/m 3 (0.2836 lb/in 3). ASTM A992 steel has the following minimum mechanical properties, according to ASTM specification A992/A992M.

    A572 steel properties are specified by ASTM International standards. [2] Grades. A572 steel has five different grades: 42, 50, 55, 60 and 65. [2]

  7. Unified numbering system - Wikipedia

    en.wikipedia.org/wiki/Unified_numbering_system

    Many material or standard specifications include a number of different UNS numbers that may be used within that specification. For example: UNS S30400 (SAE 304, Cr/Ni 18/10, Euronorm 1.4301 stainless steel) could be used to make stainless steel bars or stainless steel plates for pressure vessels or pipes . Conversely, A312 pipes could be made ...

  8. High-strength low-alloy steel - Wikipedia

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

    Microalloyed steels: Steels which contain very small additions of niobium, vanadium, and/or titanium to obtain a refined grain size and/or precipitation hardening. A common type of micro-alloyed steel is improved-formability HSLA. It has a yield strength up to 80,000 psi (550 MPa) but costs only 24% more than A36 steel (36,000 psi (250 MPa)).

  9. 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.
