The ASTM A992/A992M -11 (2015) specification defines rolled steel sections for use in building structures, bridge structures, and other commonly used structures. The standard specifies the ratios used to determine the required chemical composition for thermal analysis aspects such as: carbon, manganese, phosphorus, sulfur, vanadium, titanium, nickel, chromium, molybdenum, niobium, and copper. The standard also specifies the compressive properties required for tensile testing applications such as yield strength, tensile strength, and elongation.
ASTM A992 (Fy = 50 ksi, Fu = 65 ksi) is the preferred profile specification for wide flange sections and now replaces ASTM A36 and A572 Grade 50. ASTM A992/A992M -11 (2015) has several distinct advantages: it specifies the material's ductility, which is the maximum tensile to yield ratio of 0.85; in addition, at carbon equivalent values up to 0.5 percent, it specifies that the material's ductility is 0.85 percent. , improves the weldability of the steel at carbon equivalent values up to 0.45 (0.47 for the five profiles in Group 4); and ASTM A992/A992M -11(2015) applies to all types of hot-rolled steel profiles.
Differences between ASTM A572 Grade 50 material and ASTM A992 Grade material
ASTM A572 Grade 50 material is similar to ASTM A992 material but there are differences. Most wide flange sections used today are ASTM A992 grade. While ASTM A992 and ASTM A572 Grade 50 are generally the same, ASTM A992 is superior in terms of chemical composition and mechanical property control.
ASTM A992 has a minimum yield strength value and a minimum tensile strength value, as well as a maximum yield strength to tensile strength ratio and a maximum carbon equivalent value. ASTM A992 grade is less expensive to purchase than ASTM A572 Grade 50 (and ASTM A36 grade) for wide flange sections.
