Steel is extensively used in many applications that include construction because of its unique properties and the ease with which its properties can be enhancedfor improved performance. Due to its high malleability and strength, it can be easily machined and welded compared to other types of steel. However, the susceptibility to low performance has been associated with its low resistance to environmental degradation when exposed to corrosive or polluted environments. This study focuses on mild steel heat treatment quenched in four mediums of engine oil, water, palm oil, and air, along with its properties and corrosion susceptibility. The high temperature used for the procedure is 800 °C, 900 °C, and 1000 °C, respectively. After the heat treatment procedure, the test samples undergo corrosion testing in the sodium chloride solution for two weeks to observe the presence of corrosion products rust on its surface. The tensile machine was utilized to obtain the mechanical properties, including yield strength, tensile strength, and percentage elongation. The hardness values were obtained using the Rockwell hardness machine, and the optical microscope (OM) was used to observe the effect of the corrosion activity on the sample surface. The results obtained indicate an increase in the hardness, yield, and tensile strength, but the elongation reduces as the temperature increases.

The article presents a technology of TIG longitudinal welding without filler material (142) of heat exchanger tubes made of Lean Duplex 2101. The results of studies on the effect of heat treatment (solution annealing) on tensile strength, plasticity, delta ferrite and the structure of smooth tubes are shown. It was found, that the change in solution annealing temperature across the tested range has an impact on mechanical properties of welded tubes and the most advantageous solution annealing temperature (1050 °C) was determined.
