ASTM A790 UNS 32750 Seamless Pipes

In ASTM A790 UNS 32750, the Seamless Pipes are a variation of the Seamless Pipes. Seamless is composed of chrome and molybdenum alloys. Due to its metallurgical microstructure, Seamless has both ferritic and austenitic properties. We are calling duplex because it has both properties. Seamless materials come in three categories: duplex, super duplex, and lean duplex. Each has a different composition and mechanical properties. As the Super Duplex UNS S32750 Pipe belongs to the excellent duplex category, it uses high-strength and corrosion applications. With 25% chromium, 4% molybdenum, and 7% nickel, it has a material composition that makes it more robust and much more corrosion-resistant than ordinary duplex steel.

In this category, seamless pipes and hot-rolled welded pipes are available. The seamless pipes are more precise in their dimensions but less robust than their hot-rolled counterparts. This Duplex S32750 Seamless Pipe fits precisely without needing special tools, so you can use it in applications that require high precision in dimensions. In contrast, ASTM A790 UNS S32750 Welded Pipe is much stronger. Tubes like this have some higher absolute roughness than seamless tubes, but they’re helpful for applications that don’t require high precision. Due to its high corrosion resistance, SA 790 UNS S32750 Tube is commonly used in the chemical processing industry and in handling organic acids. SA790 S32750 UNS Bush Hex Pipe in special applications requiring hex shapes. UNS S32750 Stainless Steel ERW Pipe is electrically resistant and easily welded.
