Type 304 Stainless Steel

An analysis of tensile behavior of Type 304 stainless steel was conducted for specimens in the solution-annealed condition and after exposure to a sodium environment. The Voce equation was used to describe tensile flow curves for plastic strains above 0.005 at temperatures between 550 and 700°C and strain rates of 3.81 × 10−6 to 1.90 × 10−3 s−1. The results show that, when compared with solution-annealed specimens, the tensile flow behavior of the sodium-exposed specimens is characterized by a higher strain-hardening rate, which decreases rapidly with an increase in flow stress. The values of the saturation stress for uniform elongation predicted from the Voce model are higher for the sodium-exposed specimens than for those in the solution-annealed condition at strain rates ≲5 × 10−5 s−1 and lower for strain rates ≳5 × 10−5 s−1. Metallographic examination of the fracture surfaces shows a transition from a complete ductile fracture to a partial intergranular failure as the strain rate decreases. Carburization of the specimens appears to inhibit the intergranular failure.

Strength And Ductility

The high strain rate tensile properties of solution annealed Type 304 stainless steel have been determined experimentally. Tests were performed at strain rates ranging from 3 × 10−5 to 1 × 102 in./in./sec at temperatures from 600 to 1600 deg F. At temperatures to 1000 deg F, the strength and ductility are largely insensitive to variations in strain rate, whereas at temperatures from 1200 to 1600 deg F, significant increases in both strength and ductility are observed with increasing strain rate.
