BV-FH32 steel plate Z-direction performance:

Z-direction performance can also be called anti-layered tear steel, Z-direction performance implementation standard refers to GB/T5313 technical standard, which for the steel plate thickness direction after the average elongation after fracture and the relevant provisions of the harmful element sulfur content of the steel plate, Z-direction performance levels have three Z15, Z25, Z35, for FH32 steel plate grade Z-direction performance expression method is FH32Z15, FH32Z25, FH32Z35, or FH32-Z15, FH32-Z25, FH32-Z35.

BV-FH32 ship plate introduction

general strength hull structure steel is divided into A, D, E, F, 4 grades, the yield strength of these 4 grades of steel (not less than 235N/mm^2) and tensile strength (400~520N/mm^2) are the same, but the impact work at different temperatures is different;

The steel used for high-strength hull structure is divided into strength grades according to its minimum yield strength, and each strength grade is divided into A, D, E, and F4 grades according to its impact toughness.

The yield strength of A32, D32, E32 and F32 is not less than 315N/mm^2, and the tensile strength is 440~570N/mm^2, and A, D, E, and F respectively represent the impact toughness that can be achieved under the conditions of 0°, -20°, -40° and -60° respectively;

The yield strength of A36, D36, E36 and F36 is not less than 355N/mm^2, and the tensile strength is 490~620N/mm^2, and A, D, E, F represent the impact toughness that can be achieved at 0°, -20°, -40° and -60° respectively;

The yield strength of A40, D40, E40 and F40 is not less than 390N/mm^2, and the tensile strength is 510~660N/mm^2.

BV-FH32 Ship Plate Practical Applications:

BV-FH32 ship plate is a high-strength and high-strength hull structural steel. Shipbuilding steel generally refers to the steel used for the hull structure, which refers to the steel used to make the hull structure produced according to the requirements of the production specifications of the classification society.
