BV/E500|BV Grade E500 STEEL PLATE

BV E500 steel plate, also written as BV/E500, BV Grade E500 or market names such as EH50 / EQ51, is the extra-high-strength hull structural steel of Bureau Veritas Rules for the Classification of Steel Ships (IACS UR W16 extra-high-strength family) with 500 MPa minimum yield, 610-770 MPa tensile strength and Charpy V-notch toughness at -40°C [-40°F]. In the grade name, "E" is the toughness class, and "500" is the yield-strength level in MPa (not AH500). Gangsteel, a steel plate exporter, supplies BV E500 plates cut to size for shipbuilding, offshore platforms and marine structures.

Data source: Per IACS UR W16 (extra-high-strength hull structural steel) as adopted in Bureau Veritas hull structural steel rules, cross-checked with LR EH50 / ABS EQ51 sibling pages on gangsteel.net. Official mill/certificate grade is BV E500. Verify the current BV edition before ordering.

Per IACS UR W16 / Bureau Veritas extra-high-strength rules. Exact maxima for Ni, Cu, Cr and Mo depend on delivery condition (N/NR, TM or QT). Carbon equivalent / CET / Pcm limits apply by thickness and condition; confirm on the mill certificate and current rule edition.

Product Analysis (Check Analysis)

 

When product analysis is required, apply ASTM A6/A6M Table A permitted variations to the heat limits unless the element is min-only or not listed in Table A.

Element	Heat analysis limit	Product analysis (heat ± A6)
C	0.20 max	0.24 max
Mn	1.70 max	see A6 Table A vs heat upper limit
Si	0.10-0.55	0.05–0.61 (approx. A6)
P	0.030 max	0.040 max
S	0.030 max	0.040 max
Al (acid sol.)	0.015 min	no A6 Table A tolerance; product value not tabulated
N	0.020 max	0.025 max (typical A6 +0.005)
Nb	0.02-0.05	0.010–0.060
V	0.04-0.10	0.030–0.110
Ti	0.02 max	0.03 max
B	0.005 max	product analysis often not applicable

Product analysis applies only when specified; for a range, results may not vary both above and below it.

BV E500 Mechanical Properties

 

Grade	Yield strength, min	Tensile strength	Elongation, min
BV E500	500 MPa [73 ksi]	610-770 MPa [88-112 ksi]	16%

Per IACS UR W16 / Bureau Veritas rules (common t≤50 mm values). Yield may step down for thicker plates per UR W16; confirm thickness-dependent values on the order.

Charpy V-Notch Impact Requirements (-40°C [-40°F])

 

Thickness	Test temperature	Longitudinal, avg min	Transverse, avg min
t≤50 mm	-40°C [-40°F]	50 J	33 J
50<t≤70 mm	-40°C [-40°F]	50 J	33 J
70<t≤100 mm	-40°C [-40°F]	50 J	33 J

Per IACS UR W16 / Bureau Veritas extra-high-strength practice. Average of three full-size specimens; transverse values apply when required. Thicker plates by agreement.

Delivery Condition and Deoxidation

Deoxidation: Killed, fine-grain practice. Delivery condition: typically TMCP or QT for extra-high-strength plates; N/NR may apply at lower extra-high levels per rules. E-class (E500) grades are supplied normalized or TMCP; as-rolled delivery is not permitted for the E toughness class. Optional extras: UT, Z15/Z25/Z35, BV survey.

Thickness Coverage

Extra-high-strength BV A/D/E/F 420-690 plates are commonly supplied from about 6 mm to 100 mm thick (thicker by agreement under UR W16). Width 1500-4000 mm and length 6000-18000 mm are typical.

Equivalent Steel Grades of BV E500

GL	GL E500 steel plate
DNV	DNV E500 steel plate

IACS societies align extra-high-strength hull grades under UR W16; naming differs (BV E500, LR EH50, ABS EQ51). Dual certification is common when ordered that way.

FAQ about BV E500 Steel Plate

What is BV E500 steel plate?

It is an extra-high-strength hull structural steel under Bureau Veritas Rules (IACS UR W16 extra-high-strength family), with 500 MPa minimum yield, 610-770 MPa tensile strength and Charpy toughness at -40°C [-40°F].

What does BV E500 stand for?

BV is Bureau Veritas. The letter E is the toughness class (Charpy at -40°C [-40°F]), and 500 is the yield-strength level in MPa. Market/LR naming often uses EH50; ABS often uses EQ51. Note: BV does not use AH500 — the grade is E500, not AH500.

What is the yield strength of BV E500?

Minimum 500 MPa (73 ksi), tensile 610-770 MPa (88-112 ksi), elongation about 16% min (for the common thickness range).

What is the impact test temperature for BV E500?

Charpy V-notch at -40°C [-40°F]. Typical longitudinal average minimum is 50 J (transverse 33 J) for the tabulated thickness range on this grade page.

What is the difference between BV A500, D500, E500 and F500?

Same 500 MPa strength class. Toughness class differs: A at 0°C, D at -20°C, E at -40°C, F at -60°C. Chemistry (C, P, S, Mn) is tightened for colder classes.

How does BV E500 differ from higher-strength BV AH40?

BV AH40 is UR W11 higher-strength (390 MPa). BV E500 is UR W16 extra-high-strength (500 MPa) with different chemistry and delivery practice (often TM/QT).

Is BV E500 the same as LR EH50 or ABS EQ51?

They are IACS counterparts in the extra-high-strength family; exact chemistry/delivery options differ by society edition. Dual certification is available when surveys are arranged.

Is BV E500 weldable?

Weldable with approved procedures for extra-high-strength ship steel. Preheat, heat input and consumable matching are critical; follow the mill WPS and BV welding requirements.

What heat treatment is required for BV E500?

Extra-high-strength grades are typically delivered TMCP or quenched and tempered (QT), sometimes normalized/normalized-rolled depending on strength level and thickness. E-class (E500) grades are supplied normalized or TMCP; as-rolled delivery is not permitted for the E toughness class. Optional extras: UT, Z15/Z25/Z35, BV survey.

What thickness is available for BV E500?

Common supply is about 6-100 mm (thicker by agreement under UR W16 / BV rules), 1500-4000 mm wide and 6000-18000 mm long.
