An investigation of Environment-assisted cracking in mild steel, by Justin Opoku and Christopher C. Chama, Zambia Journal of Science & Technology, Vol.4, no.2, October 1979, Pg. 45-52.


Mild steel was tested for environment-assisted cracking behaviour in various environments. The environments were sulphuric acid-nitric acid-water, pure sodium hydroxide solution and anhydrous liquid ammonia. The specimens tested in the sulphuric acid-nitric acid-water environment were found to be more susceptible to cracking. This was probably due to the expected higher hydrogen concentration in this environment.
