BV EH32 steel plate, also written as BV/EH32, BV Grade EH32, Bureau Veritas EH32 or EH32 ship steel plate, is the higher-strength hull structural steel of Bureau Veritas Rules for the Classification of Steel Ships (IACS UR W11 higher-strength family) with 315 MPa minimum yield, 440-590 MPa tensile strength and Charpy V-notch toughness at -40°C [-40°F]. In the grade name, "E" is the toughness class, "H" means higher strength and "32" refers to the strength level (historically about 32 kgf/mm²). Gangsteel, a steel plate exporter, supplies BV EH32 / Grade EH32 plates cut to size for shipbuilding, offshore platforms and marine structures.

Data source: Per IACS UR W11 (ordinary/higher-strength hull structural steel) as adopted in Bureau Veritas hull structural steel rules. Official mill/certificate grade is BV EH32 (BV Grade EH32). Verify the current BV edition before ordering.

Per IACS UR W11 / Bureau Veritas hull structural steel rules (higher-strength grades). Nb, V and Al grain-refining elements may be used singly or in combination; when used in combination the individual minima do not apply. Where acid-soluble Al is not less than 0.015%, the Si minimum does not apply. Carbon equivalent: Ceq = C + Mn/6 + (Cr+Mo+V)/5 + (Ni+Cu)/15 (%).

Product Analysis (Check Analysis)

 

IACS UR W11 / BV rules do not separately tabulate product (check) analysis limits for higher-strength grades. When product analysis is required, the finished plate shall meet the heat limits subject to ASTM A6/A6M Table A permitted variations (same practice as other IACS societies).

Per IACS UR W11 / Bureau Veritas hull structural steel rules. Average of three full-size Charpy V-notch specimens; not more than one value below the average and none below 70% of it. Longitudinal values shown; transverse values apply when required by the rules or purchase order. Thicker plates (above 100 mm) may be supplied by agreement with adjusted impact requirements.

Delivery Condition and Deoxidation

Deoxidation: Killed, fine-grain practice. Delivery condition: E-class (EH32) grades are supplied normalized or TMCP; as-rolled delivery is not permitted for the E toughness class. Optional extras by agreement include ultrasonic testing, Z-direction (Z15/Z25/Z35) through-thickness testing and third-party Bureau Veritas survey.

Thickness Coverage

Higher-strength BV AH/DH/EH/FH 32/36/40 plates are commonly supplied from about 6 mm to 100 mm thick (up to 150 mm by agreement). Width 1500-4000 mm and length 6000-18000 mm are typical.

FAQ about BV EH32 Steel Plate

What is BV EH32 steel plate?

It is a higher-strength hull structural steel under Bureau Veritas Rules for the Classification of Steel Ships (IACS UR W11), with 315 MPa minimum yield, 440-590 MPa tensile strength and Charpy toughness at -40°C [-40°F]. The mill certificate grade is BV EH32 (BV Grade EH32).

What does BV EH32 / Grade EH32 stand for?

BV is Bureau Veritas. The letter E is the toughness class (Charpy at -40°C [-40°F]), H means higher strength, and 32 is the strength level (historically about 32 kgf/mm², now 315 MPa min yield).

What is the yield strength of BV EH32?

Minimum 315 MPa (46 ksi), tensile 440-590 MPa (64-85 ksi), elongation about 22% min.

What is the impact test temperature for BV EH32?

Charpy V-notch at -40°C [-40°F]. Longitudinal average minima are 31 J up to 50 mm, 38 J for 50-70 mm and 46 J for 70-100 mm.

What is the difference between BV EH32 and other 32-class grades?

Same 315 MPa strength class. BV AH32 at 0°C [32°F]; BV DH32 at -20°C [-4°F]; BV EH32 at -40°C [-40°F]; BV FH32 at -60°C [-76°F]. Delivery condition follows the toughness letter rules.

What is the difference between BV EH32 and BV EH36?

Same E-class toughness (Charpy at -40°C [-40°F]). BV EH32 is strength class 32 (315 MPa min yield); BV EH36 is strength class 36 (355 MPa min yield).

Is BV EH32 the same as ABS EH32 or LR EH32?

Requirements are essentially harmonized under IACS UR W11. ABS EH32, LR EH32, DNV E32 and ASTM A131 EH32 (where listed) are counterparts; dual certification is common when ordered with the required surveys.

Is BV EH32 weldable?

Yes. Controlled carbon and Ceq give good weldability; preheat may be required for thick sections depending on Ceq and restraint.

What heat treatment is required for BV EH32?

E-class (EH32) grades are supplied normalized or TMCP; as-rolled delivery is not permitted for the E toughness class.

What thickness is available for BV EH32?

Typical supply is about 6-100 mm thick (up to 150 mm by agreement), 1500-4000 mm wide and 6000-18000 mm long.
