FH36 steel for offshore engineering is a high-strength, high-toughness low alloy steel, which is widely used in the field of offshore engineering, including the construction and repair of ships, offshore platforms, submarine pipelines and other structures.
FH36 steel for offshore engineering has excellent mechanical properties and welding performance, its main features are as follows:
1. High strength: the yield strength of FH36 steel reaches more than 355MPa, and the tensile strength reaches more than 490MPa, which has higher load bearing capacity than ordinary carbon structural steel.
2. High toughness: FH36 steel has better impact toughness and can maintain better toughness in low temperature environment to avoid safety accidents caused by brittle fracture.
3. good welding performance: FH36 steel has a low carbon equivalent, welding is not easy to produce cracks, and the mechanical properties of the weld metal is similar to the base material, to ensure the overall performance of the structure.
4. Good corrosion resistance: FH36 steel has a certain amount of alloying elements added, such as copper, nickel, chromium, etc., so that it has good resistance to seawater corrosion, suitable for the marine environment.
FH36 steel for marine engineering is widely used in the following fields because of its excellent performance:
1. Shipbuilding: FH36 steel is the main structural material for large ships, such as oil tankers, bulk carriers, container ships and so on. Its high strength and good welding performance make the hull structure safer and more reliable.
2. Offshore platforms: FH36 steel is used for the construction of offshore oil drilling platforms, subsea oil and gas production platforms and other marine engineering structures, which can withstand the challenges of the extreme marine environment.
3. Submarine pipeline: FH36 steel has good corrosion resistance and high strength, suitable for the manufacture of submarine oil and gas pipeline, to ensure the safe operation of the pipeline.
