Applications of ASTM A131 Grade E in Shipbuilding

Grade E steel is commonly used in:

1. Ship hull structures
2. Deck plating
3. Bulkheads
4. Mobile offshore drilling units and structures

Its moderate strength and excellent low-temperature toughness make it suitable for various marine structural applications.

Manufacturing Process and Available Dimensions

Grade E steel is typically manufactured as plate steel. Available dimensions include:

• Thickness: 0.197″ – 3.94″ (5.00 – 100 mm)
• Width: 75″ – 129.9″ (1900 – 3299 mm)
• Length: 240″ – 590″ (6100 – 15000 mm)

Comparison of Grade E with Other ASTM A131 Grades

Grade E offers superior low-temperature toughness compared to other grades, making it suitable for a wider range of operating conditions.

Quality Standards and Testing for ASTM A131 Grade E

Grade E undergoes rigorous testing, including:

1. Tensile strength testing
2. Chemical composition analysis
3. Charpy V-notch impact testing (27 J @ -40°C for plates up to 50 mm thick)
4. Ultrasonic testing for internal defects
