■ Overview
Oil and offshore platform steel plate in API 2H specification,the steel grade API 2H Gr50 is with yield strength above 345 Mpa and tensile strength within 483 Mpa to 620 Mpa when rolling.API 2H Grade 50 steel plates are intended for fabrication primarily by cold forming and welding. API 2H Gr50 steel plate produced to this specification are used for welded construction of offshore structures in selected critical sections that must exhibit good impact properties and resistance to fatigue and through-thickness or lamellar tearing. The primary use of these steels is in tubular joints, stiffened plate construction, and other intersections whereportions of the plates will be subjected to tension in the through-thickness (Z) direction.
