Supplier of API 2W Grade 60 Plates, Exporters of API 2W Grade 60 Plates, Stockist of API 2W Grade 60 Plates

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

This grade is produced by the thermomechanical control process (TMCP) which yields a fine-grained steel with high strength combined with high toughness and excellent formability. The low carbon content and CEQ lead to excellent weldability. Toughness in the heat-affected zone (HAZ) and high resistance against cold cracking produce better welded structures. This can also be ABS certified.

API 2W Grade 60 Marine steel is a kind of high tensile strength marine steel. All of these steels have been engineered to be optimal long-lived shipbuilding steels.API 2WGr60 shipbuilding steel plates are mainly used for making the offshore oil drilling platform, the hull of ship building and ship repairing, the platform pipe joints and other components.

A thermo-mechanically control processed (TMCP) structural steel plate spec for the offshore industry, primarily used in shipbuilding, offshore platforms, jack-up rigs, and offshore wind parks. This spec offers a high degree of toughness and excellent weldability.

Produced vacuum degassed, fine grain, and fully killed with theromechanical rolling and accelerated cooling in grades 50 (up to 6”) and 60 (up to 4”). Weldability is critical and plates are supplied under this spec with a max carbon equivalence (CE) of 0.39-0.45 depending on grade and thickness. Tensile minimum is 65 KSI for grade 52 and 75 KSI for grade 60. Yield minimums are 50 KSI and 60 KSI for the corresponding grade. Plates are commonly ordered with Charpy Impacts at -40° F.

Our API-2W GR 60 is stocked with the following supplements:

  • S1 – Ultrasonic Examination per A578 Level C.
  • S3 – Individual Plate Testing for Mechanical Properties.
  • S4 – Through-Thickness (Z-Direction) Testing
  • S5 – Low Sulfur for Improved Through-Thickness Properties
  • S7 – Low Nitrogen for Improved Notch Toughness in Strain-Aged Condition
  • S8 – Strain-Aged Charpy V-Notch Impact Testing
  • S11 – Preproduction Qualification Per API RP 2Z with Crack Tip Opening Displacement (CTOD)
