■ Overview
Oil and offshore platform steel plate in En 10225 specification,the steel grade S355G2+N with normalized heat treatment.S355G2+N oil platform 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.
