Stockist of Offshore Steel Plates, Supplier of Offshore Steel Plates & Exporters of Offshore Steel Plates

API 2W Grade 50T steel plate is produced in accordance with the fifth edition (December 2006) of API’s Specification 2W. This specification allows for the production of intermediate strength steel plate utilizing Thermo-Mechanical Control Processing (TMCP). Depending on customer preference, API 2W can normally be directly substituted for plate ordered to API Specification 2H or API Specification 2Y. In many situations, customers actually prefer API 2W because due to its low-carbon content it offers superior weldability to that of either API 2H or API 2Y.

Structural steel plate API 2W Grade 50T is intended primarily for use in offshore structures in critical portions that must exhibit good impact toughness and resistance to plastic fatigue loading and lamellar tearing. The primary use of API 2W Grade 50T is in tubular joints, stiffened plate construction and other intersections where portions of the plates will be subjected to tension in the through-thickness (Z) direction.The test Z15,Z25,Z35 shall be done for these API oil and offshore platform steel plate API 2W Gr50T.

API Monogram
Arrow Pipes & Plates Industries API 2W Grade 50T plate is licensed by the American Petroleum Institute to carry the API monogram.
Typical Applications
API 2W Grade 50T steel plates are intended for fabrication primarily by cold forming and welding. Plate produced to this specification is used for welded construction of offshore structures in selected critical sections that must exhibit good impact properties and resistance to fatigue and lamellar tearing.

Charpy Impact Properties
One Charpy V-notch test, consisting of three transverse specimens, is made on each plate rolled that is produced by TMCP. The specimens are taken from the mid-width and mid-thickness locations of the plate. Due to the low carbon and sulfur contents of API 2W plates, the energy of the full-size specimens will often exceed the limits of ASTM E23; therefore, sub-sized specimens are allowed per the following table:
