checking the bases for allowable stresses per K302.3.2 for unlisted material (B31.3 - B705 N06625)in which allowable stress should not exceed 2/3 of Syt, where do you find values for Ry: ratio of avg temp dependent trend curve value of yield strength to room temp yield strength?

per eq (31): Syt = Sy * Ry

many thanks.
