Offshore Steel Plate – API 2H Grade 50

API 2H Grade 50 is an offshore steel grade which is regulated by the American Bureau of Shipbuilding (ABS).

Applications of API 2H Grade 50 Offshore Steel Plate

Whilst originally designed as a structural steel for use in the welded construction of offshore platforms, the material is also used in other applications due to the tight controls placed on the chemical composition of the steel at the mill stage.

The primary use of API 2H Grade 50 is in critical areas of the construction where good impact and fatigue resistance is required. API 2H Grade 50 can be found in stiffened plate construction, tubular joints, and other intersections where parts of the plates are subjected to through-thickness tension.

The steel is also used as a piling material for bridge construction due to its fracture, vibration and torque resistance. API 2H Grade 50 is therefore not only in effective material for floating and rigid offshore platform construction, it also has other uses as a high yield and highly specified structural grade material.
