Corrosive and Mechanical Experimental Tests for Selected Stainless Steel Pipes

Abstract

The article presents corrosion tests of small diameters pipes made of stainless steel OH17N12M2 chromium - nickel - molybdenum with material number 1.4401 EN 10088 which does not have a pronounced yield point. The samples were subjected to corrosion in a laboratory at room temperature in solutions of sulfuric and hydrochloric acid at specified concentrations and in a given time. Corrosion was observed as surface uniform. As a result of the analysis, the dependences showing the mass loss as a function of time were obtained and the corrosion rate and average speed were determined. Following that, some of the corroded and non-corroded samples were subjected to a bending test in the Instron 3382 testing machine. On the basis of the measurements, plots showing maximum deflection of a beam as a function of bending load were created and compared. It was determined that the samples which were corroded for 720 h in 5% H2SO4 were not corroded and retained the bending capacity. Samples corroded for longer period of time or in more potent acids had the bending capacity reduced which was noted
