API 2H Grade 50 is a structural steel plate that is used in offshore structures. Kloeckner Metals routinely supplies API 2H Grade 50 across our 40+ branches nationwide.
This grade offers intermediate strength. It has high impact toughness and high resistant to fatigue loading. It is also tough classed as a marine & offshore steel plate grade and can be used in different of applications because of its stringent specifications.
It is often used in the construction industry as well as the marine and shipbuilding industry.
It is typically used in applications where good impact and fatigue strength is required. Examples are tubular joints, stiffened plate construction, and bridge construction.
For the industries and applications it serves, weldability is critical, since it is typically used in welded construction for offshore structures.
It is heat treatable.
