A high-strength low-alloy steel plate that is utilized in a variety of structural applications. This specification is produced in Grades 42, 50, 55, 60 & 65, the grades representing the yield strength. Plates that are 4 and thicker are made to a 42 KSI yield, although material can be modified to reach the 50 KSI min yield.

ASTM A572 Grade 50 Steel Equivalent, Gr 65, 60 Properties 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. ASTM A572 Steel Plate - A572 Grade 42, 50, 55, 60, 65 ASTM A572 is Recommended for 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.

A572 steel is available in five different grades:42, 50, 55, 60, and 65. Each grade number indicates the yield strength of this high strength, low alloy steel. Its multiple favorable properties make it a staple for construction applications. Strength, Weldability, and Machinability. One of the most commonly used A572 grades is A572-50. SPECIFICATIONSThe establishment of specific welding techniques depends upon many factors such as temperature of A572 Gr.50 KFG 4 & HSS 100 4 16 5/8 380T* 55T* A572 Gr.55 KFG HSS-- 16 5/8 400T 60T A572 Gr.60 KFG 2 20 Plates and bars of all CSA G40.21M grades can be Steel Reference Guidestrength but higher tensile strength than A572 due to the addition of copper and slightly higher carbon content. ASTM A572 - High-Strength Low-Alloy Structural Steel This specification covers high-strength structural quality shapes generally suitable for use in riveted, bolted, or welded construction, and for general structural purposes.

The main horseshoe itself was formed from two box girders of A572 grade 50 carbon steel. The fabrication is performed in accordance with the structural welding Code of AWS D1.1. The girder sections are 2 inches thick, 6 feet long and 2.5 feet wide. They were shipped in 40-foot sections and assembled on site. a572 grade 50 coil used in bridge engineering tolerance One of the most commonly used A572 grades is A572-50.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. Bridge Standards and Procedures Manual - Volume 1 6.Grades of steel used in bridge construction shall preferably be based on their availability.The following sections and grades ASTM A572 Grade 50 Steel Plates and A572m 55/ 60/ 65 hshr plate astm a572 grade 50 is a high strength, low alloy steel plate that offers an optimum combination of strength, weldability and notch toughness with economy. post-weld heat treatment of sa572 grade 50 may degrade heat-affected zone strength and toughness. Pretesting of specific welding and post-weld heat-treating procedures is suggested to assure perfection of final property levels.
