Abstract
High strength low alloy (HSLA) steels are a relatively new group of alloys having higher strength as a result of composition and processing variations. Because these HSLA steels are being widely used in applications susceptible to a few cycles of stress or strain in the plastic region, the low cycle fatigue (LCF) properties of these steels are very important to design engineers; and as a result, a knowledge of the extent of the effects of several steel variables (viz, thickness, composition, processing variables, and so forth) and cold-work on the LCF properties of a single steel grade is very desirable from design safety considerations. Specimens obtained from a commercial grade of hot-rolled, pickled and oiled Nb-bearing, fine grained HSLA steel covering three thicknesses, two heats and four coil-positions were characterized as regards to their monotonie and cyclic properties. The present study indicates that the LCF behavior of this commerical grade steel is very insensitive to “steel variables” such as composition, thickness and coil-position. The large increase in monotonie strength obtained by cold-work is not retained under cyclic loading and the LCF behavior of cold-worked samples approached that of undeformed material.
