General Description

When it comes to building tough ships and offshore platforms that can handle freezing cold and heavy loads, BV Grade FH36 steel plate is a top pick.

This high-strength steel is made for extreme marine conditions, offering great toughness in super cold weather, easy welding, and good resistance to rust from saltwater. It’s part of the “FH” family, which means it’s built for high performance in freezing temps.

At SHH STEEL, we make and send out BV FH36 plates that follow strict Bureau Veritas (BV) rules. These plates are often used in ship hulls, decks, and other parts for vessels in polar areas.

What makes BV Grade FH36 special? It keeps its strength even at -60°C, helping ships stay safe and last longer in icy seas. If you’re in shipbuilding or engineering, knowing about BV FH36 steel plate can help you choose the right material for your project.

Material Specification

BV Grade FH36 is classified as a high-strength steel under BV rules, in the “FH” group for better tensile and extreme cold toughness.

It’s usually hot-rolled and can use thermo-mechanical controlled processing (TMCP) to get a fine structure that boosts its qualities. It follows BV Rules for the Classification of Steel Ships, perfect for ships in very cold waters.

At SHH STEEL, every BV FH36 plate is certified and ready for worldwide use.

Thickness and Sizes Available

We offer BV FH36 steel plates in different sizes for ship projects in cold areas. This range helps with custom builds and cuts down waste.

Note: Traces like copper or chromium may add for better rust fight.

Mechanical Properties

BV FH36 steel plate has strong features for heavy loads in freezing ship work.

It has high yield to fight bending, solid tensile for lasting power, and good stretch for shaping without snaps.

It also passes impact tests at -60°C for tough in ice-cold. These help BV Grade FH36 handle waves, bumps, and wear in polar.

Vs. basic steels, BV/FH36 gives top performance for cold marine jobs.

Delivery Conditions

At SHH STEEL, we deliver BV FH36 steel plates ready for your needs.

Main states: normalized rolling (heat to 900°C, air cool) for better toughness.

For thick plates, thermo-mechanical controlled processing (TMCP) mixes rolling and cooling for strength without weld loss.

Plates include BV cert, with MTC per EN 10204 3.1 or 3.2, proving spec match.

Packed with waterproof and wood crates.

Times 15-30 days, rush options. Global shipping.

FAQ

What is the difference between BV FH36 and BV EH36 steel plates?
BV FH36 and EH36 are both high-strength steels with 355 MPa yield and 490-620 MPa tensile, but FH36 is impact-tested at -60°C for extreme cold toughness, while EH36 is at -40°C. FH36 is better for polar regions to avoid brittleness, but EH36 suffices for less severe arctic conditions. Both weld well, but choose based on temperature requirements.
What are the chemical composition requirements for BV FH36 marine grade steel?
BV FH36 limits carbon to 0.16%, manganese between 0.90-1.60%, silicon up to 0.50%, phosphorus and sulfur to 0.025% each for good weldability and toughness. Aluminum is min 0.015% for grain refinement, with niobium 0.02-0.05% and vanadium 0.05-0.10%. Check the MTC for your batch's exact ladle or product analysis.
How does BV FH36 steel perform in low-temperature environments compared to other grades?
BV FH36 performs excellently at -60°C with 34J impact, making it superior for extreme cold; compared to EH36 (-40°C) or DH36 (-20°C), it's better for polar routes, while AH36 (0°C) is for milder conditions. It's a staple for ice-class ships.
What are the typical applications and uses of BV Grade FH36 steel plate in shipbuilding?
BV Grade FH36 is typically used for hulls, decks, and bulkheads in ice-class vessels due to its high strength and cold toughness. It's also ideal for offshore platforms, risers, and marine gear in freezing waters. It handles fatigue and salt well, making vessels safer.
Is BV FH36 steel plate suitable for welding, and what precautions should be taken?
Yes, BV FH36 is highly weldable with methods like SMAW or GMAW. For thicker plates (over 50mm), preheat to 100-150°C to prevent cracking, use low-hydrogen electrodes. Post-weld heat treatment may be optional but follow BV guidelines for strong, defect-free joints.

Conclusion

BV FH36 steel plate is a powerhouse in the shipbuilding world, offering unmatched strength, reliability, and value for extreme cold applications.

From its precise specifications to versatile applications, it’s clear why this marine grade is a top pick for professionals.
