Stainless steel s31254 Chemical Composition

The production process of S31254 254SMO Duplex Steel Pipes involves the use of advanced melt refining techniques such as the AOD, ESR, or VOD. The use of these techniques helps to achieve higher purity levels, which results in improved mechanical and corrosion-resistant properties. The pipes are then subjected to various hot and cold working processes that help to shape and refine their internal and external surfaces. The final pipes are subjected to strict quality checks, including mechanical testing, ultrasonic testing, and eddy current testing.
