Sep 18, 2002 · ASTM A36 steel is classified as AWS Group I material and, as such, may be welded with non-low-hydrogen processes. In contrast, ASTM A572 Grade 50 steel is classified as AWS Group II material, which, because of its higher yield strength, must be welded using low-hydrogen processes. A572 Steel Plate - Grade 50, 42, 55, 60 & 65 Lapham Lapham-Hickey Steel delivers durable, versatile ASTM A572 steel plate in five grades including Grade 50 - for a wide variety of uses; from building transmission towers and train cars to creating truck frames. Lapham-Hickey Steels ASTM A572 steel plate is available in five grades:42, 50, 55, 60 & 65.
ASTM A572. The ASTM A572 specification is the Standard Specification for High-Strength Low-Alloy Columbium-Vanadium Structural Steel for plates, structural shapes, sheet pilings and bars. ASTM A572 includes five grades with specified minimum yield strengths of 42, 50, 55, 60, and 65 ksi, respectively. For applications where notch toughness is ASTM A572 Grade 50 Plate, ASME A572 GR. 50 Carbon Steel A572 Grade 50 Plates have high strength, form-ability, and excellent welding properties making it suitable for a large variety of different applications.A572 Grade 50 Sheets and Plates are commonly used in structural applications including cranes, truck frames, building structures, heavy construction equipment, bridges, liners, freight cars ASTM A572 Grade 50 Steel Equivalent, Gr 65, 60 Properties ASTM A572 Grade 50 Steel ASTM A572 grade 50 steel is a low-alloy high-strength structural steel with a yield strength of 50 ksi (345 MPa) and a tensile strength of 65 ksi (450 MPa). It has better mechanical properties than ASTM A36 steel. ASTM A572 contains 5 yield point grades:Grade 42, Grade 50, Grade 55, Grade 60 and Grade 65.
Applications of A572 Steel Plates:Grades 42, 50, 55 are intended for riveted, bolted or welded structurals, Grade 60 and 65 are for riveted and bolted construction of bridges, welded constructions and more applications.
