2017年4月18日 · This specifiation covers the standard requirements for Grades 42 [290], 50 [345], 55 [380], 60 [415], and 65 [450] 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 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 is a common high strength, low alloy (HSLA) structural steel used in the United States. [1] A572 steel properties are specified by ASTM International standards. [2]

2025年2月17日 · ASTM A572 steel is available in five grades: 42, 50, 55, 60, and 65. The grade number corresponds to the minimum yield strength in kilopounds per square inch (ksi). For example, A572 Grade 50 provides a minimum yield strength of 50 ksi.

2025年2月28日 · ASTM A572 is a type of high-strength, low-alloy steel known for its strength, versatility, and cost-effectiveness. It is widely used in structural applications where durability, load-bearing capacity, and weldability are essential. The material is available in five grades, each designed to meet specific structural needs.

The below table outlines the material properties for ASTM A572 material including the young's modulus, yield strength, ultimate strength and other relevant mechanical properties required for structural and mechanical design.

ASTM A572. The 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.

1.1 This specification covers five grades of high-strength low-alloy structural steel shapes, plates, sheet piling, and bars. Grades 42 [290], 50 [345], and 55 [380] are intended for riveted, bolted, or welded structures.

Alro stocks ASTM A572, a high strength, low alloy steel plate that offers an optimum combination of strength, weldability and notch toughness with economy. ASTM A572's Post-weld heat treatment may degrade heat-affected zone strength and toughness.
