ASTM A572 Grade 42 50 55 60 65 Low Alloy Pipe
High-Strength Low-Alloy Structural Steel Tube for Transporting Fluid
Specification
ASTM A572 is a specification for high-strength low-alloy structural steel plates and bars for use in building structures and other applications. The grades of A572 steel are categorized based on their yield strength, with Grade 42, 50, 55, 60, and 65 being the most common. These grades are designed to provide improved mechanical properties and greater resistance to atmospheric corrosion compared to conventional carbon steels.
Key Features
- High Strength: Offers excellent yield and tensile strength.
- Low Alloy: Contains a small percentage of alloying elements, enhancing strength and toughness.
- Versatility: Suitable for a wide range of structural applications.
- Weldability: Good weldability makes it ideal for construction and fabrication.
- Corrosion Resistance: Better resistance to corrosion compared to standard carbon steels.
