Flow in a low-carbon steel at various temperatures.

Abstract

This report relates to flow (elongation) in 0.25 per cent carbon steel subjected to a fixed total load in tension at approximately constant temperature within the range 70 to 1,100°F. (20 to 595°C ). The character of flow is described, and the factors governing selection of maximum allowable stresses are discussed for service in which very long life and freedom from appreciable deformation must be considered.Comparisons are also given between maximum allowable stresses and the stress-strain relations determined in the customary short-time tension tests at various temperatures.
