The product is a superaustenitic stainless steel offered as pipe and plate under the UNS N08031 designation, commonly known as Nicrofer 3127 or Alloy 31. Its nominal composition is Ni 30-32 %, Cr 26-28 %, Mo 6-7 %, Cu 1-2 % with the balance being iron. Huanan Special Steel Co. supplies the material in both seamless pipe and welded plate forms that meet ASTM B625. The size range listed by the supplier covers thicknesses from 0.1 mm to 300 mm, widths 500-2000 mm and lengths 3000-6000 mm.
These dimensions place the alloy within the typical envelope used for high temperature and highly corrosive process equipment. Industry practice rates the alloy’s tensile strength around 620 MPa and its density near 8.0 g/cm3, values that are standard for this nickel-chromium-molybdenum family. The material retains oxidation resistance up to approximately 1200 °C, a temperature capability that aligns with standard specifications for super austenitic grades. Typical heat treatment procedures involve solution annealing to optimise corrosion performance.
Customers such as chemical-process plants, offshore oil-and-gas facilities and marine-service manufacturers commonly specify this alloy for heat exchangers, pressure vessels and seawater-exposed components. The supplier’s catalogue does not disclose minimum order quantities, lead times or payment terms, so buyers should request these details directly. Trade is usually conducted on FOB or CIF terms, with inspections arranged prior to shipment.

Before placing an order, verify that Huanan Special Steel Co. can furnish a current mill test certificate that details the chemical composition and mechanical properties of the UNS N08031 batch. Request a sample or a recent inspection report to confirm surface finish and dimensional tolerances. Check the company’s harbour-level trust tier and ask for references or third‑party audit results to substantiate its manufacturing capability.
Discuss the preferred Incoterms with the supplier; common choices for steel shipments from China are FOB Shanghai or CIF Ningbo. Because the listing does not specify lead time, ask for an estimated production schedule and shipping duration for the required dimensions. Clarify payment conditions, such as a letter of credit at sight or a partial advance, and ensure that any banking fees are agreed in advance.
Arrange an independent third‑party inspection before loading, focusing on thickness, width, length and surface defects. Non‑destructive testing, such as ultrasonic or radiographic examination, can be requested to verify internal integrity, especially for pressure‑vessel pipe. Ensure that the final shipment includes the mill test certificate, a compliance statement to ASTM B625 and any required customs documentation for steel imports into your destination country.
