Dr. Haider Mahdi Layth, Dr. Basil Shaneen Manahi, and Dr. Haider Moaz Muhammad, teachers from the College of Engineering, University of Basra, published a joint research entitled Improving the corrosion behavior and mechanical properties of stainless steel AISI 316 under heat treatment and previous cold work. In the reputable German magazine Nonlinear Engineering Q2, which is one of the reputable international magazines, stainless steel is considered an important innovation in the field of petroleum in particular. The study of the effect of heat treatments (HT) and cold forming on corrosion behavior, surface hardness, and microstructure in a different corrosion environment, such as Seawater and crude oil. Corrosion rates (CRs) were obtained using a weight loss approach, Which was then improved using the Taguchi method. The specimens used in this study are made of 316 stainless steel bar, which was first annealed. The characteristics of the raw material were obtained before and examined through tensile testing to evaluate the mechanical properties of the metal. After cold forming, the hardness was tested, corrosion tested using the lost weight method, as well as All microstructure tests were performed. By performing these tests, the metal shows excellent mechanical properties such as yield stress, tensile stress, and hardness and also the raw metal showed higher corrosion resistance in seawater than crude oil, while in cold working and in-work thermal treatments, the samples show higher corrosion in treated samples. Thermal only.
The aim of the research is to improve the corrosion resistance of stainless steel 316, and stainless steel is considered an important innovation in the field of petroleum in particular.
