DH32 steel is widely used in:
Its high strength and good low-temperature toughness make it ideal for these applications.
DH32 steel is typically manufactured as plate steel. Available dimensions include:
Grade | Yield Strength (min) | Impact Test Temperature |
---|---|---|
AH32 | 315 MPa | 32°F (0°C) |
DH32 | 315 MPa | -4°F (-20°C) |
EH32 | 315 MPa | -40°F (-40°C) |
DH32 offers improved low-temperature toughness compared to AH32, making it suitable for a wider range of operating conditions.
DH32 undergoes rigorous testing, including:
At HL Steel Company, we ensure that all our ASTM A131 Grade DH32 steel meets or exceeds these quality standards, providing our customers with reliable and high-performance products for their shipbuilding and offshore structural needs.
