Products FAQ

Yes. As a Grade E high-strength structural steel for marine applications, CCS EH32 shipbuilding steel plate has undergone Charpy V-notch impact testing at -40°C. For applications requiring even lower temperatures, we can supply plates certified for impact toughness at -60°C upon request.

The main difference between the two lies in the temperature at which the impact toughness test is conducted.

CCS DH32 requires impact testing to be carried out at -20°C;

CCS EH32 requires impact testing to be carried out at -40°C.

Consequently, EH32 offers superior low-temperature impact resistance, making it more suitable for extremely cold marine environments and providing greater safety.

Depending on your project requirements, we supply CCS DH36 shipbuilding steel plates in normalized (N), thermomechanically controlled process (TMCP), controlled rolled (CR) or hot rolled (HR) conditions.

Of course. We can customize dimensions, heat treatment, and surface treatment based on customer drawings to meet the specific construction requirements of various marine projects.

The DH36 has better low-temperature toughness (impact at -20°C) than the AH36 (impact at 0°C), making it suitable for cold waters.

The CCS DH36 and ABS DH36 have consistent key mechanical properties: a minimum yield strength of 355 MPa and a tensile strength range of 490 - 630 MPa.

The difference between the two lies in the certifying classification societies: CCS stands for China Classification Society, and ABS stands for American Bureau of Shipping.

Both materials are widely recognized and accepted by the international shipbuilding industry.

Of course. We can arrange for third-party inspections (SGS, BV, LR) at our factory prior to shipment, as requested by the customer.

Yes. All of our CCS DH32 shipbuilding steel plates are officially certified by CCS and are subject to inspection by third-party agencies such as SGS.

We provide customised processing services including ultrasonic testing, Z-direction testing, low-temperature impact testing, cut-to-size cutting, surface treatment (sandblasting, rust removal, oiling and painting, etc.), and heat treatment, to meet a wide range of engineering and construction requirements.

The key difference between the two lies in the certification body and the corresponding flag state requirements.

CCS DH32: Applicable to vessels flying the Chinese flag, certified by the China Classification Society (CCS).

ABS DH32: More widely recognised for projects in the United States, South Korea and the Middle East, certified by the American Bureau of Shipping (ABS).

DH32 is a high-strength marine steel plate, and certification from multiple classification societies may be applied for simultaneously as required.
