Surface heat treatment methods for LR EH32 shipbuilding steel plates

Our quality control department will do inspection for details of the steel materials LR EH32 shipbuilding steel plates before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.

The yield strength of AH36, DH36, LR EH32 shipbuilding steel plates, EH36, and FH36 Steel for high-strength hull structure is not less than 355MPa, and the tensile strength is 490 ~ 620MPa. The letter A, D, E, and F indicate the impact toughness that they can achieve at 0°C, -20°C, -40°C and -60°C respectively. The yield strength of Grade AH40, DH40, EH40, FH40 hull structural steel is not less than 390MPa, the tensile strength is 510 ~ 660MPa.

Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. LR EH32 shipbuilding steel plates Heat treatment process refers to the ability to change the microstructure and properties of LR EH32 shipbuilding steel plates after heat treatment, including hardenability, hardenability, temper brittleness, etc.
