ASTM A514 steel has several grades, each optimized for specific thickness and mechanical properties, though they all share a high yield strength and are often used in applications requiring a high strength-to-weight ratio. Here are the primary A514 grades:
A514 Grade A
A514 Grade B
A514 Grade E
A514 Grade F
A514 Grade H
A514 Grade P
A514 Grade Q
A514 Grade S
A514 Grade B and A514 Grade E are commonly used for heavy equipment and structural applications.
A514 Grade Q is the most popular due to its balance of thickness and mechanical properties, used frequently in construction.
A514 Grade H is often used in situations that require additional thickness, as it maintains strength at a higher gauge.
Each grade differs slightly in thickness limitations and has specific mechanical properties tailored to various industrial applications.
All grades share a minimum yield strength of 100 ksi (690 MPa) and tensile strength ranging from 110–130 ksi (760–895 MPa), though these values can vary slightly based on the specific grade and thickness.
