ASTM A572, specification for High-strength low-alloy Columbium-Vanadium structural steel plate. This specification covers 5 grades and 4 types of high strength low alloy structural steel shapes, plates, piling, bars. Grade 42, 50, 55, 60, 65 and type 1, 2,2 3, 5. Low alloy and high strength structural steel plate is widely used in engineering structure applications, such as building structure, construction machinery, mine machinery, truck, bridge, pressure vessel, etc.
Hot Rolled Steel A36 (ASTM A36) is the most commonly available grades of the hot-rolled steels which has good overall mechanical properties, is easily fabricated and may be formed hot or cold. Due to the hot roll process the surface on this steel will be rough when compared to cold rolled. ASTM A36 yield strength is also less than C1018.
Q235 ordinary carbon structural steel, also known as A3 steel. Ordinary carbon structural steel - plain plate is a type of steel material. Q represents the yield limit of this material, followed by 235, which refers to the yield value of this material, around 235MPa. And as the thickness of the material increases, its yield value will decrease. Due to its moderate carbon content, good comprehensive performance, and a good combination of strength, plasticity, and welding performance, it is the most widely used.
Q195 is a carbon structural steel with a yield strength of 195MPA, which has the advantages of high plasticity, toughness, and welding performance. Usually applied in fields such as architecture, structure, and vehicles.
