Steel Plate: High Strength Low Alloy (HSLA)
High Strength Low Alloy or (HSLA) steel plate, is easy to form and weld, while providing greater corrosion resistance than conventional carbon steel. They are used in a variety of uses, including construction, bridges, buildings, machinery, truck frames, crane booms, and general fabrication.
Common Characteristics of High-Strength Low-Alloy Steel (HSLA)
HSLA steel is a popular and excellent choice aplications requiring a good strength-to-weight ratio. HSLA steel is resistant to rust, corrosion resistance is increased through the addition of copper, silicon, nickel, chromium, and phoshporus. The strength of the steel plate is increased by adding copper, niobium, titanium, and vanadium. This increased strength typically requires a range of 25 to 30 % more power to form. However, formability of the steel is increased through the addition of calcium, zirconium, and rare earth elements.
ASTM A36 Steel Plate
A36 steel is used in the construction of bridges, pre-fabricated buildings, industrial and commercial buildings.
ASTM A572 Steel Grade 42, 50, 60, 65
A572 is another common structural steel used in the construction of bridges, buildings, and construction equipment.
