WebAustenitic Stainless Steel – Definition. Austenitic stainless steel contains between 16 and 25% of chromium and can also contain nitrogen in solution, both of which contribute to their relatively high corrosion resistance. In metallurgy, stainless steel is a steel alloy with at least 10.5% chromium with or without other alloying elements and ... WebApr 11, 2024 · Hydrogen inside the pipe steel is produced due to the corrosion reaction between hydrogen sulfide and metal matrix.
