ASTM A1011. The A1011 specification is the Standard Specification for light gauge Hot-Rolled Sheet and Strip Carbon(CS and DS), Structural(SS), High-Strength Low-Alloy(HSLAS), High-Strength Low-Alloy with Improved Formability(HSLAS-F), and Ultra-High Strength(UHSS) steels in thicknesses up to 0.230"(6 mm) in coil form.
ASTM A529 GR 50,A529 GR 55 steel plate steel plate,ASTM ASTM A529 specification covers high-strength carbon-manganese steel shapes, plates, and bars of structural quality for use in riveted, bolted, or welded construction of buildings and for general structural purposes. Materials considered here are available in Grades 50  and 55 . Steel specimens shall be killed, and as such, be affirmed in the corresponding test report.
1.1 This specification covers five grades of high-strength low-alloy structural steel shapes, plates, sheet piling, and bars. Grades 42 , 50 , and 55  are intended for riveted, bolted, or welded structures. Grades 60  and 65  are intended for riveted or bolted construction of bridges, or for riveted, bolted, or welded construction in other applications.
ASTM A572 Gr.50/55/60/65 Angles - Katalor Steel SheetASTM A572 Gr.50/55/60/65 is a high-strength, low-alloy steel angles. ASTM A572 Gr.50/55/60/65 angle has high yield and tensile strength, the high tensile strength of A572 Gr.50/55/60/65 angles allows reduction of section thickness and weight in production,
ASTM A572 Steel - Ultra-High Strength - CopperloyA572 Grade 50 has a 139% greater Yield Strength than A36 steel. A572 steel does not require preheat or post heating during the welding process and standard AWS D1.1 welding standards apply. Higher grades of steels will require preheating which is not economical compared to savings in weight. Welding wire for A572 Grade 50 that is used has a yield higher than the material. With stronger steels the welding wire yield strength
yield and tensile strength can be obtained by specifying ASTM A529 Grade 55, ASTM A572 Grades 55, 60 or 65, or ASTM A913 Grades 60, 65 or 70. W-shapes with atmospheric corrosion resistance (weather-ing characteristics) can be obtained by specifying ASTM A588 Grade 50. These and other material specifications applicable to

Grade 50 is a Columbium-Vanadium steel that offers a minimum yield of 50,000 PSI. In addition, ASTM A572 Grade 50 is noted for its increased resistance to atmospheric corrosion. Grade 50 contains more alloying elements than plain carbon steel and thus is somewhat more difficult to form.
