UNS R30556,Super Alloy Haynes 556
The UNS R30556 alloy, commonly known as Haynes 556, is a nickel‑cobalt‑chromium superalloy supplied as seamless pipe and butt‑welding fittings. It meets ASTM and ASME specifications such as B622 and SB622 for seamless tubing and SB‑366 for buttwelding components. The alloy is prized for its high‑temperature strength and oxidation resistance, making it a frequent choice for aerospace gas turbines, chemical reactors and power‑generation equipment. Its composition includes nickel, cobalt, chromium and small amounts of aluminium and titanium to enhance creep resistance.
Shangdun offers Haynes 556 in a variety of forms, including plates (B435) and welded tubing, all derived from internally smelted slabs and bars. Typical industry dimensions for this superalloy range from 10 mm to 250 mm in outer diameter with wall thicknesses between 1.5 mm and 25 mm, and a diameter tolerance of ±0.05 mm is common. The material is usually solution‑annealed and subsequently age‑treated to achieve the required high‑temperature mechanical properties, with a typical maximum service temperature of about 1150 °C. These parameters align with the performance expectations for superalloys used in extreme environments.
Potential buyers include turbine manufacturers, petrochemical plant engineers and high‑temperature furnace builders who require a material that can sustain prolonged exposure to temperatures above 1000 °C. The product is offered in bulk quantities, with packaging formats that can be clarified with the supplier. Since the listing does not disclose trade terms, incoterms or payment conditions, interested importers should negotiate these details directly with Shangdun.

Shangdun Special Materials Co.Ltd. operates from Shisheng Industrial Park in the Jiangding District of Jiaxing, Zhejiang Province, China (postal code 314000). The company is classified as an imported tier supplier with a harbor trust tier, indicating reliance on overseas specialty metal sources. Its recorded response rate is 0 % and there is no average response time, suggesting that communication may be limited and should be verified before proceeding.
The supplier’s product range includes the Haynes 556 superalloy in seamless pipes, welded tubing, butt‑welding fittings and plate forms, all manufactured from slabs and bars produced in‑house. The listing does not provide specific certifications, production capacity or client references, so buyers are advised to request any needed documentation directly from Shangdun.
UNS R30556 (Haynes 556) is a nickel-cobalt-chromium superalloy with outstanding high-temperature strength and oxidation resistance, supplied as ASTM/ASME B622 seamless pipes and SB-366 buttwelding fittings. This specialty alloy is widely used in aerospace gas turbines, chemical processing, and power generation where corrosion and thermal fatigue are critical concerns. Available in plates (B435) and welded tubing configurations, Haynes 556 commands a significant price premium over standard stainless steel due to its superior performance in extreme environments, making it a high-value commodity in the international special metals trade.

Sourcing UNS R30556, Super Alloy Haynes 556 from Shangdun Special Materials Co.Ltd. - China Import Guide
Confirm that the alloy grade, heat‑treatment condition and dimensional tolerances meet the design requirements of your high‑temperature equipment. Request the mill test report and any relevant certification to substantiate the chemical composition and mechanical properties of the UNS R30556 material.
Discuss and agree on the incoterm, expected lead time and payment schedule with the supplier, as these are not disclosed in the listing. Verify whether the shipment will be in coil form, bundled sections or individual pieces, and arrange freight forwarding accordingly for the China export route.
Plan for an independent inspection at the loading port or upon arrival to ensure that the pipe dimensions, surface condition and heat‑treatment state conform to the agreed specifications. Ensure that the commercial invoice, packing list, certificate of origin and any test reports accompany the cargo before final acceptance.
