May 30, 2020 · Both ASTM A36 carbon steel and ASTM A572 grade 50 are iron alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a very high 99% of their average alloy composition in common. For each property being compared, the top bar is ASTM A36 carbon steel and the bottom bar is ASTM A572 grade 50.
ASTM A572 Grade 55 high strength low alloy structure steel ASTM A572 Grade 55 high strength low alloy structure steel plates are produced under ASTM A572/ A572M standard, just as same as grade A572 Gr.42, A572 Gr.50, A572 Gr60 and A572 Gr65. Compare with A572 Gr.42 and A572 Gr.50 steel plates, ASTM A572 Grade 55 high strength low alloy structure steel plates have higher yield strength and tensile strength.
ASTM A572 steel plate is made of ASTM AA572, a High-Strength Low-Alloy, Columbium-Vanadium Structural Steel. There are five grades of high-strength low-alloy structural steel shapes, plates, sheet piling, and bars. Grades 42 , 50 , and 55  are best for riveted, bolted, or welded structures.

The article you have selected begins on the next page = 58 ksi), although ASTM A572 grade 50 (F y = 50 ksi; F u = 65 ksi) is increas-ingly very common. M-shapes with higher yield and ten-sile strength can be obtained by specify-ing ASTM A572 grade 42, 50, 60 or 65, or A529 grade 42 or 50. M-shapes with atmospheric corrosion resistance (weathering) characteristics can be obtained by specifying ASTM

ASTM A36 (F y = 36 ksi, F u = 58 ksi) remains common, but 50 ksi grades increasingly are being used, including ASTM A572 Grade 50, ASTM A529 Grade 50 or ASTM A992; eachASTM A572 - SSAB high-strength steelThe ASTM A572 specification is the Standard Specification for High-Strength Low-Alloy Columbium-Vanadium Structural Steel for plates used in general construction and structural applications. ASTM A572 includes five grades with specified minimum yield strengths of 42, 50, 55, 60, and 65 ksi, respectively.
