1 Scope

1.1 COVERAGE

This specification covers one grade of intermediate strength steel plates, through 2½, inches thick, for use in welded construction of offshore structures. These steels are intended for fabrication primarily by cold forming and welding as per API Spec 2B. The welding procedure is of fundamental importance, and it is presumed that procedures will be suitable for the steels and their intended service. Conversely, the steel should be amenable to fabrication and welding under shipyard and offshore conditions. These steels are suitable for use in selected portions of offshore structures which must resist impact and plastic fatigue loading.

1.2 PRIMARY APPLICATION

The primary use of these steels is for Class "B" applications as defined in API RP 2A. API Specifications 2H, 2W, and 2Y cover other steels providing improved mechanical properties and toughness for Class "A" applications and should be used where substantial z-direction stresses are expected.
