FAQ

Q1:

Is ABS EH32 marine steel plate easy to weld?

ABS EH32 marine steel plate has good weldability with low carbon equivalent. It is suitable for SAW, GMAW and SMAW processes.

Q2:

What is the equivalent grade of ABS EH32?

The international equivalent grades of ABS EH32 are as follows:

Chinese standard: GB/T 712 EH32

American standard: ASTM A131 EH32

Class society equivalents: CCS EH32, DNV EH32, BV EH32, LR EH32

All grades possess the same chemical and mechanical properties.

Q3:

What are the delivery conditions for ABS Grade EH32 marine steel plates?

This depends on the thickness. Typically, it is supplied in a TMCP or normalised condition to meet the mechanical property requirements.

Q4:

Do you offer Z-direction performance testing (Z15, Z25, Z35)?

Yes, we can supply EH32 steel plates with Z-direction performance testing in accordance with customer requirements.

Q5:

What is the maximum thickness of your ABS EH32 shipbuilding steel plates?

The ABS EH32 shipbuilding steel plates we supply are typically available in thicknesses ranging from 5 to 150 mm. For extra-thick plates (over 100 mm), we use the TMCP process to ensure product performance.

Q6:

What is the main difference between ABS Grade EH32 and DH32?

The main difference between the two lies in the minimum impact test temperature.

DH32: The impact test temperature is -20°C.

EH32: The impact test temperature is -40°C, which is a more stringent requirement.

Consequently, EH32 is suitable for lower ambient temperatures or colder marine environments, whilst DH32 is suitable for milder marine environments.

Q7:

What is the difference between ABS AH32, DH32, EH32 and FH32?

ABS Grade AH32, DH32, EH32 and FH32 shipbuilding steel plates have the same strength. The core difference is low-temperature impact resistance.

Grade	Impact Test Temperature	Impact Energy, KV₂ / J	Suitable for Marine Environments
ABS AH32	0°C	31(Longitudinal), 22(Transverse)	Standard marine environments.
ABS DH32	-20°C	31(Longitudinal), 22(Transverse)	Cold-water marine environments.
ABS EH32	-40°C	31(Longitudinal), 22(Transverse)	Polar marine environments with extremely low temperatures.
ABS FH32	-60°C	31(Longitudinal), 22(Transverse)	Polar/ice regions and ultra-low-temperature deep-sea environments.

Q8:

Do you provide ABS certification documents for your ABS shipbuilding plates?

Yes, all our ABS shipbuilding plates are certified by the American Bureau of Shipping (ABS). We will provide full certification documents and a Material Test Certificate (MTC) to ensure that our ABS steel plate products comply with international maritime industry regulations and meet the acceptance requirements for our customers’ projects.

Q9:

Can ABS shipbuilding steel plates be supplied in normalized conditions?

Yes. Depending on the thickness (typically 40 mm or more), we can supply ABS shipbuilding steel plates in either normalized (N) or thermomechanically controlled process (TMCP) conditions to improve the grain structure.
