Products FAQ

The key difference between the two lies in their low-temperature impact toughness ratings:

LR EH36: Suitable for extremely cold polar environments, with stable ultra-low-temperature impact toughness at -40°C;

LR DH36: Suitable only for conventional low-temperature environments down to -20°C; it does not meet the safety requirements for polar projects.

Both have a minimum yield strength of 355 MPa, but EH36 offers greater adaptability to extreme environments and broader engineering applicability, covering all application scenarios for DH36.

Yes. LR EH36 shipbuilding steel is the core structural steel used in polar icebreakers and heavy-duty polar offshore facilities. It features high load-bearing capacity and impact toughness at temperatures as low as -40°C, enabling it to effectively withstand extreme cold and impact loads from ice waves, and fully meet the stringent safety and durability requirements of polar navigation projects.

Yes. Our LR Grade EH36 marine steel plate fully complies with the relevant marine steel standards of major classification societies, including CCS, ABS, BV, NK, and DNV. We can provide dual or multiple classification society joint certifications based on customer requirements to meet the acceptance standards for offshore engineering projects in ultra-cold regions across different countries or regions.

Yes. All of our LR Grade EH36 shipbuilding steel plates hold valid official certification from Lloyd’s Register (LR) and EN 10204 3.2 factory test reports. These certificates are recognized worldwide and meet the requirements for international shipyard tenders, polar offshore engineering acceptance, and cross-border customs clearance.

There are two main standard delivery conditions that comply with LR specifications:

Thermomechanically Controlled Processed (TMCP): Suitable for steel plates with a thickness of ≤ 50 mm; offers short delivery lead times and high cost-effectiveness;

Normalized (N): Suitable for plates with a thickness > 50 mm, or for applications with special requirements for low-temperature toughness, such as polar vessels; it provides more stable low-temperature impact performance.

In addition, we can provide LR EH32 shipbuilding steel plates with Z15 / Z25 / Z35 full-thickness laminar tear resistance upon request.

Both possess ultra-low-temperature impact toughness at -40°C. The key differences lie in their strength grades and intended applications:

LR EH32: Minimum yield strength of 315 MPa; excellent formability; better value for money; suitable for conventional ultra-low-temperature offshore structural engineering;

LR EH36: Minimum yield strength of 355 MPa; offers greater load-bearing capacity and is specifically designed for heavy-duty cryogenic offshore engineering projects with higher structural safety requirements and load demands.

The key difference between the two lies in their low-temperature impact toughness ratings.

LR EH32: Requires impact toughness at -40°C, offers excellent resistance to brittle fracture, and is suitable for polar and extremely cold marine environments;

LR DH32: Requires impact toughness at -20°C only; it is suitable for conventional low-temperature scenarios but does not meet the safety standards for polar projects.

Both have a minimum yield strength of 315 MPa, but LR EH32 has a broader low-temperature operating range and is suitable for more severe polar conditions.

LR Grade EH32 is a Grade 32 high-strength structural steel plate for shipbuilding that offers excellent low-temperature impact toughness at -40°C and stable load-bearing capacity. It is primarily used in the core load-bearing structures of polar ocean-going vessels, oil tankers, and bulk carriers operating in cold regions, as well as in critical support components for polar deep-sea offshore platforms and marine engineering facilities in extremely cold regions. It is the ideal material for shipbuilding and polar marine engineering projects in extremely cold regions worldwide.

LR DH36 shipbuilding steel plates are designed with an optimized composition featuring low carbon and low impurities, providing excellent low-temperature weldability and compatibility with all conventional, high-standard shipbuilding welding processes. At temperatures as low as -20°C, stable and reliable joint quality can be achieved by following standard welding procedures. No complex preheating or special crack-prevention measures are required, effectively reducing the difficulty of construction in cold regions and improving project efficiency.
