API 2Y Grade 60 STEEL PLATE

High Strength Structural API 2Y Grade 60,API 2YGr60,API 2YGr60 steel plate is for welded construction of offshore structures/offshore platforms in selected critical portions which must resist impact, plastic fatigue loading, and lamellar tearing. API 2Y Grade60 high strength steel plates are delivered in the Roller Quenched and Tempered (QT) condition. The final levels of strength and toughness are achieved by tempering heat treatments performed in furnaces with uniform temperature distribution and close temperature control. Using this method, plates satisfying grades requiring nominal yields of 420 MPa,450 MPa and 460 MPa can all be produced from steel slab or ingots of similar target compositions.
