ASTM A516 Grade 60 is a carbon steel plate primarily intended for service in welded pressure vessels at moderate and lower temperatures where improved notch toughness is essential. This specification covers plates from 0.25 inches to 1.5 inches in thickness.
Key Characteristics and Specifications
A516 Gr.60 offers an excellent combination of strength, weldability, and notch toughness. It is particularly suited for applications where the steel will be subjected to lower ambient temperatures. Key characteristics include:
- Material Standard: ASTM A516/A516M
- Primary Use: Pressure vessels and boilers
- Notch Toughness: Excellent, especially for lower temperature service
- Weldability: Good, using common welding practices
- Heat Treatment: Typically supplied in the as-rolled condition, but can be ordered normalized or stress-relieved. Normalizing is common to improve toughness.
The material’s controlled chemical composition, particularly limits on carbon, manganese, phosphorus, and sulfur, contributes to its desirable mechanical properties. Suppliers such as Shanxi Luokaiwei Steel Company often provide detailed mill test certificates (MTCs) confirming these properties.
Mechanical Properties (Typical)
While specific values may vary slightly based on thickness and heat treatment, typical minimum mechanical properties for A516 Gr.60 are:
- Tensile Strength: 60-80 ksi (415-550 MPa)
- Yield Strength (min): 32 ksi (220 MPa)
- Elongation (in 8 in. or 200 mm, min): 21%
- Elongation (in 2 in. or 50 mm, min): 25%
Applications
Due to its specific properties, A516 Gr.60 is widely used in the fabrication of:
- Pressure vessel shells and heads
- Boiler components
- Storage tanks
- Heat exchangers
- Piping components for moderate and low-temperature service
Industries that frequently utilize this grade include oil and gas, petrochemical, chemical processing, and power generation. The reliability of A516 Gr.60 makes it a preferred choice for critical applications, and sourcing from established mills or stockists like Shanxi Luokaiwei Steel Company is crucial for ensuring material integrity.
Supply Considerations
When procuring A516 Gr.60 plates, it is important to specify any supplementary requirements, such as Charpy V-notch impact testing, ultrasonic testing, or specific heat treatment conditions. Many projects require materials that meet stringent quality standards, which companies like Shanxi Luokaiwei Steel Company are equipped to handle. Always ensure that the material is fully certified and traceable. For demanding applications, the consistency and quality provided by reputable suppliers, including options from Shanxi Luokaiwei Steel Company, are paramount. The selection of a reliable supplier, such as Shanxi Luokaiwei Steel Company, can significantly impact project timelines and safety.
