As you can see, APPA 73 is a structural steel grade with a yield strength of 50, 60, 70, 80, or 90 ksi and an ultimate tensile strength of 65, 75, 85, 95, or 105 ksi. It has an elongation in 2 inches of 19, 20, 21, 22, or 23% and a Charpy V-notch impact energy of 20, 22, 24, 26, or 28 ft-lbs at -20°F. APPA 73 is comparable to ASTM A709 and ASTM A572, which are also structural steel grades with similar properties. APPA 73 is typically used in applications where high strength and toughness are required, such as bridges, buildings, and other structures.

Here are some additional details about each of the three grades:

• APPA 73: This grade is known for its high strength and toughness. It is often used in applications where heavy loads or impact forces are present, such as bridges, buildings, and other structures.
• ASTM A709: This grade is similar to APPA 73 in terms of strength and toughness. It is often used in applications where high strength is required, such as bridges and buildings.
• ASTM A572: This grade is slightly less strong than APPA 73 and ASTM A709. It is often used in applications where cost is a factor, such as non-load-bearing structures.

Ultimately, the best grade for your application will depend on the specific requirements of the project. If you need a high-strength steel with good toughness, then APPA 73, ASTM A709, or ASTM A572 would all be good options. If you are on a tight budget, then ASTM A572 may be the best choice.

APPA 73 Pros/Cons and My Thought
