ASTM A572 steel plate is made of A572, 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 [290], 50 [345], and 55 [380] are best for riveted, bolted, or welded structures.

ASTM A572 65 is a high strength low alloy columbium vanadium structural steel. This specification provides for a 65ksi minimum yield strength and an 80ksi minimum tensile strength. The primary application for ASTM A572 65 is galvanized transmission and lighting poles.

HSLA steel encompasses a large range of grades, but three grades comprise a large percentage of HSLA steel demand in North America. ASTM A572. Like A36, ASTM A572 is a widely used, economically priced structural steel material.

A572 is a high strength low alloy steel plate used in a variety of structural applications. The most common grade Chapel Steel stocks is Grade 50.

Tolerance under specified thickness .010". A 3/4 x 52" wide plate, for example, would have a tolerance range of .740/.780" Because of tolerances, i.e. thickness, flatness and camber, as well as the hot roll condition, ASTM A572 Grade 50 generally does not finish to specified thickness.

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 covers five grades of high strength, low alloy structural steel shapes, plates, and bars. All grades are intended for riveted, bolted, or welded structures, with the exception that grades 60 and 65 are not intended for welded bridge applications.

Jul 02, 2007 · Actually, many steel producers in the early 90's started "dual certifying" their steel so that it satisfied the minimum requirements of both A36 and A572. That way they didn't have to produce and stock two different grades.

The comparisons were used to calculate the DIF of each steel at strain rates ranging from 0.002 to 2.0 inch/inch/second. Experiments revealed that A572 50 steel exhibited an increase in yield strength up to 35% and ultimate tensile strength up to 20% as strain rate increased over the range tested.

Jan 31, 2005 · Hello All, I'm in the middle of purchasing materials for use in making built up beams in which the end service is frames for a metal building. These frames are engineered to be made from carbon steel with a minimum yield strength of 50 KSI. We typically use A572 grade 50 and sometimes use "A36 modified" or A36 material that has a 50 KSI min yield or greater.
