Abstract:
Tests were made of the corrosion cracking tendency of high strength steel in solutions of 20 H2SO4 with NaCl 30 g1 admixture with results of testing in a fresh humid chamber, salt haze chamber, imitating tropical conditions, and in an atmosphere of an industrial region. It was established, that with the increase in critical stress, derived when testing stressed samples in a 20 H2SO4 solution with an admixture of 30 gl NaCl, the time until the beginning of cracking of the stressed steel 145 kg sq mm increases in the mentioned media. Steel of various fusions having critical stress values, when testing in a pickling solution, of more than 50 kgsq mm is not inclined toward corrosion cracking in an atmosphere of an industrial region. Tests in 20 H2SO4 with addition of 30 gl NaCl solution may serve as bases for the development of a rapid method for the determination of the tendency of high strength steel toward corrosion cracking.
