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.
A572 H beam is a high strength low alloy steel used in a variety of structural applications. A572 H beam is produced in Grades 42, 50, 60 & 65the grades representing the yield strength. The most common grade Chapel stocks is Grade 50 which is produced up to 4 thick. ASTM A992 Steel Beam & Channel / A572 Grade 50 Steel A992 is the most commonly used structural steel in construction and is used to make I beams, Wide Flange, as well as channels, plates, angles and other shapes. It is a structural steel containing small additions of vanadium or columbium, copper, nickel, chrome, and molybdenum, which provide A992 with better material definition. In most cases it can be dual certified to A572 grade 50, exhibiting the high strength and improved weight-to-strength found in A572 ASTM Structural Steel Standards Infra-Metals Co.This grade has an ultimate tensile strength of 65,300 psi and a high tensile yield strength of 50,000 psi. It is used in a broad array of structural applications, some of which include buildings, transmission towers, bridges, construction equipment, and truck frames. In addition to its strength, A572 maintains excellent ductility, allowing it to be machined by multiple techniques and easily welded.
This specifiation covers the standard requirements for Grades 42 , 50 , 55 , 60 , and 65  of high-strength low-alloy columbium-vanadium structural steel shapes, plates, sheet piling, and bars for applications in bolted, welded, and riveted structures in bridges and buildings. Astm A572 Steel Sheet Plate Grades 42,50,55,60,65 A572-50 plate is ductile and easy to form. It can be successfully machined with the appropriate techniques and is easy to weld. It is a high strength low alloy (HSLA) columbium-vanadium steel and is available in grades 42, 55, 60 and 65. ASTM A572 steel plate is used in a variety of structural applications including bridges, buildings, construction equipment, freight cars, machinery, truck parts Effect of temperature on creep in ASTM A572 high range 1155 % of room temperature yield stress. 3.1 Test specimens For high-temperature creep tests, rectangular steel coupons were cut from A572 Gr. 50 steel sheets. The chemical composition of A572 steel is different from that of conventional A36 steels. The chemical compo-sition of both types of steel, together with actual

Jun 26, 2007 · Good Answers:3. # 6. Re:Welding ASTM 572 grade 65. 06/17/2007 11:35 AM. I am not sure about the carbon content of Grade 65. If the tensile strength of the base metal is 80,000 psi, then it is advisable to heat the base metal to min. 100 0 C (210 0 ASTM A572 Steel Beam - Excellent Weight-Strength RatioIts low content of alloy elements such as columbium & vanadium optimize the properties in strength and atmospheric corrosion. Owing to its high strength of 50,000 ksi yield strength, A572-50 steel I sections are increasingly replacing common carbon steel beam like A36 which should be thicker to satisfy the strength requirement.
