GET PRICEAPI 2W grade 50 is a thermo-mechanical controlled steel plate for marine structures. API 2W grade 50 has a good impact resistance, plastic fatigue load, lamellar tearing ability and very good welding process. API 2W grade 50 steel plate is mainly used for cold forming and welding process, the marine structure of the welded structure. API 2W grade 50steel plate should be suitable for welding in shipyards and marine conditions.
