Import A790 Tube — Buy in Bulk from Supplier in China

The A790 tube from Sable Trade Co., Ltd is a seamless duplex stainless steel tube manufactured from UNS S32205, a grade known for its high strength and exceptional corrosion resistance. The tube is supplied in an annealed and pickled condition, with dimensions of 88.9 mm outer diameter and 5.49 mm wall thickness, making it suitable for high-pressure and high-temperature applications. It meets the requirements of ASTM A790, which governs duplex stainless steel tubular products for general corrosion-resistant service.

UNS S32205 typically contains 22-23% chromium, 4.5-6.5% nickel, 3-3.5% molybdenum, and 0.14-0.20% nitrogen, providing a balanced microstructure of approximately 50% ferrite and 50% austenite. This composition delivers superior resistance to stress corrosion cracking, pitting, and crevice corrosion compared to 316L austenitic stainless steel. The tube’s seamless construction ensures uniform mechanical properties, while the annealed and pickled finish removes scale and enhances corrosion resistance.

This A790 tube is engineered for use in oil and gas exploration, chemical processing, and construction industries where reliability and longevity are critical. Its precise dimensions and material properties make it ideal for applications such as heat exchangers, pressure vessels, and hydraulic systems. Sable Trade Co., Ltd, based in Xiamen, Fujian, specialises in supplying such tubular products for international markets. Buyers should confirm packaging, MOQ, and lead time directly with the supplier, as these details are tailored to individual orders.
