These stainless steel 321/321H electropolished pipes are made up of chromium (17–19%), nickel (9–13%), and titanium (0.3–0.8%), with the 321H variant featuring a higher carbon content for enhanced strength at elevated temperatures. This unique blend offers remarkable resistance to intergranular corrosion, oxidation, and thermal fatigue. The pipes boast impressive tensile strength ranging from 515 to 700 MPa, yield strength between 205 and 275 MPa, elongation of 35 to 40%, and hardness below 90 HRB. The electropolishing process takes the surface smoothness up a notch, minimizes contamination, and boosts the pipes’ resistance to corrosion and scaling.
