What is ASTM A 572?
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.
What is ASTM A572 gr50?
A572 Grade 50 steel plate is a HSLA steel that is considered a workhorse grade of steel. Because of its strength, less material is needed to meet application requirements than with other grades of steel.
What is the difference between A36 and A572 steel?
The higher presence of strengthening alloys, such as manganese and silicon, in A572 plate grades give the material greater strength as compared to A36. This higher strength allows A572 steel to bear more weight and withstand greater forces without breaking or failing, which is crucial in structural applications.
Is A572 Grade 50 hard?
Grade 50 is a Columbium-Vanadium steel that offers a minimum yield of 50,000 PSI. In addition, ASTM A572 Grade 50 is noted for its increased resistance to atmospheric corrosion. Grade 50 contains more alloying elements than plain carbon steel and thus is somewhat more difficult to form.
What kind of steel is A572?
high-strength low-alloy
ASTM A572 steel plate is a popular grade of high-strength low-alloy (HSLA) steel that is typically used in structural applications. A572 steel contains chemical alloys that enhance the material’s hardness and ability to bear weight, and this material is lightweight relative to steel grades with similar compositions.
What is the tensile ultimate stress for ASTM A572 Gr 55 steel?

| Density | 7.80 g/cc | Typical of ASTM Steel |
| Mechanical Properties | Metric | Comments |
| Tensile Strength, Ultimate | 485 MPa | |
| Tensile Strength, Yield | 380 MPa |
What is A572 steel used for?
A572 steel is typically used in structural applications due to its high strength, ductility, weldability and corrosion resistance. These applications include structural sections, reinforcing bars, bridges, skyscrapers and houses.
What is ASTM A572 Grade 60?
ASTM A572 covers structural quality, high strength, columbium-vanadium low alloy steel. Used for structural steel shapes in the construction of bridges, building or similar structures. It may be joined by riveting, bolting or welding. Machinability of Grade 60 alloy is fair.
Is A572 better than A36?
Used in bridges, buildings, construction equipment, transmission towers and more, A572 has a higher yield point and tensile strength than A36. In other words, in can bear more weight. A572 is available in multiple grades (we look at four grades here) that offer different strength and hardness benefits.
Can you weld A572 to A36?
Weldability of the two steels is the same. Welds on the two steels (A36 and A36/A572 Gr 50 dual grade) using identical electrodes nuxcs and weld- ing parameters produced acceptable, ~quivalent welded JOints.
Can A572 be heat treated?
While their heat treatment process is not regulated, AR400 and AR500 are typically quenched and tempered….3. Quenching & Tempering.
| Grade | Yield Point | Tensile |
|---|---|---|
| A514 ≤ 2.5” to 6” thick | 90 ksi | 100-130 ksi |
| A572 Grade 50 | 50 ksi | 65 ksi |
