Tensile strength, s447, ksi [MPa] Elongation in 2 in. Combining values from the two systems may result in non-conformance with the standard. The specimen shall be mounted in the testing furnace and held within this range of temperature for 1 h, and the test load then applied. The xstm shall undergo tension test after aging and short-time high-temperature tension test and shall conform to the required values of tensile strength and elongation.
