Offshore Steel Plate – API 2W Grade 50 from Masteel

Thermo-mechanically rolled for extra strength and toughness, API 2W Grade 50 is a structural offshore steel grade which is regulated by the American Bureau of Shipbuilding (ABS).

Applications of API 2W Grade 50 Offshore Steel Plate

The material is used in the production of floating and rigid offshore oil and gas platforms and is used commonly in intersections of the structure due to the materials superior strength combined with good impact and fatigue resistance.

Properties of API 2W Grade 50 Offshore Steel Plate

API 2W Grade 50 provides good toughness around the heat affected zone (HAZ) so is an ideal material for use in the welded joints of the construction.

The stringent chemical composition of the material makes API 2W Grade 50 an excellent structural steel where resistance to fracture, vibration or torque is required (as found in bridge construction).

The steel has arguably better welding characteristics than API 2H Grade 50 due to the materials lower carbon content.

Key Features of API 2W Grade 50 Offshore Steel Plate

Key features of API 2W Grade 50 Offshore Steel Plate include:

  • Structural offshore grade for critical applications
  • Lower carbon content for improved weldability
  • Thermo-mechanically rolled for extra strength and toughness
  • Good impact resistance in heat affected zone (HAZ)
  • Resistance to lamellar tearing
