API 2Y Gr60 oil platform steel plate
Source:Xin Steel Industry Date:2013/07/31
API 2Y Grade60 is High Strength Structural Steel Plate, 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.
