STUDY OF THE TENACITY AND RESISTANCE TO STRESS CORROSION OF STEEL WITH STRENGTH BETWEEN 1200 AND 1400 N/MM2

ETUDE DE LA TENACITE ET DE LA RESISTANCE A LA CORROSION SOUS CONTRAINTE D'ACIERS AYANT UNE RESISTANCE COMPRISE ENTRE 1200 ET 1400 N/MM2

In order to study the influence of different metallurgic parameters on tenacity and resistance to stress corrosion, a comparison was made of the behaviour of six grades of steel. Emphasis was placed on the values introduced by fracture mechanics, and an attempt is made to relate these values and the characteristics obtained with the most common test methods. These values generally decrease when strength increases. At a given strength level, steel with the lower carbon content averages the best tenacity. The different correlations between tenacity and resilience, and tensile characteristics permit to forecast a correct order of magnitude of tenacity, if the ductile or fragile fracture behaviour is taken into account. Stress corrosion resistance tests were carried out on smooth samples (measurement of fracture time) and notched samples in a sodium chloride environment. Sensitivity to stress corrosion increases markedly when the elastic limit exceeds approximately 1000 n/mm2, but the effect is more or less noticeable depending on the composition and structure of steel.
