API 2MT1 grade 50 is an API Offshore Structural Steel Grades. API spec 2MT1 is applicable for Carbon Manganese Steel Plate with Improved Toughness for Offshore Structures.
API 2MT1 specification covers one grade of intermediate strength steel plates, though 2 ½ in. thick, and suitable to use in welded construction of offshore structures. Fabrication of these API 2MT1 material can be done by cold forming and welding as per API Spec 2B. The minimum yield strength of API 2MT1 is 50 ksi [345 MPa] and a minimum transverse Charpy V-notch impact toughness of 30 ft-lbf [41 J] at 0°F [-18°C].
API 2MT1 is mainly used in offshore structures for Class “B” applications as defined in API RP 2A. API 2MT1 steel plates are workable for use in select portions of offshore structures which must resist impact and plastic fatigue loading but are not subjected to substantial through-thickness (Z-direction) stresses.
