Uniaxial tensile test data for P91 n t material at 200 °C (specimen identifier T9-1-44)

The data collection consists of tensile and fracture toughness test data which were performed in the frame of MATTER project (Grant agreement number 269706). Tensile test data includes tests in air, ArH2 and LBE environments at strain rates ranging from 5E-4 to 5E-7 between RT and 400 Celsius. Fracture toughness test data includes reference tests in air with a speed of 0.2 mm/min at 250 Celsius.
