The ASTM B622 N06225 nickel alloy tube from ARK Steel Tube Company is a seamless tubular product engineered for extreme service conditions. Made from UNS N06625, this Inconel 625 grade contains approximately 58% nickel, 21% chromium, 9% molybdenum, and 3.5% niobium plus tantalum, with trace titanium and aluminum. It is designed to withstand temperatures up to 1,800°F and resists chloride-ion stress corrosion cracking and pitting, making it suitable for chemical processing, offshore oil and gas, aerospace, and power generation.
This alloy offers enhanced corrosion resistance, toughness, and strength at both high and low temperatures, outperforming stainless steel in demanding environments. The tubes are typically supplied in random lengths or cut-to-order, with plain or beveled ends, and are traded globally under HS code 7504.00 for seamless nickel pipes and tubes. The material’s composition ensures superior performance in aggressive media, including oxidizing and reducing acids.
Primary buyers include chemical plants, oil and gas operators, and aerospace manufacturers seeking reliable materials for high-temperature and high-pressure applications. The product’s compliance with ASTM B622 and related standards such as B163, B407, and B444 ensures consistency in mechanical properties and dimensional tolerances. ARK Steel Tube Company sources its tubes from mills in Asia, providing a cost-effective option for global importers.

Before ordering, verify the alloy’s chemical composition and mechanical properties against ASTM B622 and B444 standards. Request mill test certificates (MTCs) to confirm compliance with the specified grade (UNS N06625) and ensure the tubes meet your application’s temperature and corrosion resistance requirements. Cross-check dimensions and tolerances to avoid mismatches with your system.
Confirm logistics details such as lead time, which can vary based on tube length and quantity. ARK Steel Tube Company typically ships from Taizhou, China, so discuss Incoterms (e.g., FOB Ningbo or Shanghai) and packaging to protect the tubes during transit. Clarify payment terms, as these are often negotiable for bulk orders.
Inspect the tubes upon arrival for surface defects, dimensional accuracy, and end finish. Perform non-destructive testing (NDT) such as eddy current or ultrasonic testing if required for critical applications. Ensure all documentation, including MTCs and HS code 7504.00 classification, is provided to facilitate customs clearance.
