Chemical Composition and Mechanical Properties of ASTM A131 Grade AH32

ASTM A131 Grade AH32 is a high-strength structural steel with the following properties:

The chemical composition includes a maximum carbon content of 0.18% and a maximum CEV of 0.36%.

Applications of ASTM A131 Grade AH32 in Shipbuilding and Offshore Structures

AH32 steel is widely used in:

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

Its high strength and good impact toughness make it ideal for these applications.

Manufacturing Process and Available Forms of AH32 Steel

AH32 steel is typically manufactured as plate steel. Available dimensions include:

• Thickness: 0.251″ – 1.50″ (6.38 – 38.1 mm)
• Width: 72″ – 120″ (1800 – 3050 mm)
• Length: 240″ – 1020″ (6100 – 25910 mm)

Comparison of AH32 with Other ASTM A131 Grades

AH32 offers a balance of strength and toughness suitable for most shipbuilding applications.

Quality Standards and Testing for ASTM A131 Grade AH32

AH32 undergoes rigorous testing, including:

1. Tensile strength testing
2. Chemical composition analysis
3. Charpy V-notch impact testing (23 ft-lbs @ 32°F)
4. Ultrasonic testing for internal defects
