About Danyang HB Special Alloy Co., Ltd - Nickel Alloy Supplier in China

China‑based Danyang HB Special Alloy Co., Ltd, located in Danyang, Jiangsu, lists fifteen distinct alloy products in its current catalogue. The catalogue groups the items under the HS‑code families 7504, 7505, 7507 and 7508, covering nickel‑copper, nickel‑chromium and nickel‑based super‑alloys used in high‑temperature and corrosive environments. Each entry specifies either a commercial name such as Hastelloy C‑276 or an UNS designation like N08811 for Incoloy 800HT, providing a clear reference for buyers. The supplier’s top categories also include stainless steel pipe components, agriculture and petroleum by‑products, indicating a broader industrial focus beyond the alloy list.

The product list features well‑known grades: Hastelloy C‑276 (UNS N10276), Incoloy 800HT (UNS N08811), Incoloy 825 (UNS N08825), Inconel 600, 625, 718 and X‑750, Nimonic 75 and 80A, Monel 400 and K‑500, as well as generic Nickel 200 entries. HS codes are provided for each alloy where applicable, for example 7507.12 for Hastelloy C‑276 and 7508.90 for Inconel 625. The presence of both named and UNS‑coded items gives buyers the ability to match specifications to international standards such as ASTM B575, AMS 5609, or EN‑ISO 15156.

Product Range and Specialties of Danyang HB Special Alloy Co., Ltd

The catalogue concentrates on nickel‑based alloys that are widely used in chemical processing, aerospace, oil‑field and power‑generation sectors. Typical grades include Hastelloy C‑276 (high‑temperature corrosion resistance), Incoloy 800HT (high‑temperature strength), Inconel 718 (high‑strength super‑alloy), and Monel 400 (nickel‑copper alloy with excellent seawater resistance). Industry specifications often reference ASTM standards (e.g., ASTM B575 for Hastelloy, ASTM B443 for Incoloy 800HT) and AMS/ISO grades for aerospace applications. Buyers also encounter material condition designations such as annealed, solution‑annealed, or aged, which affect mechanical properties like tensile strength (typically 620‑1 150 MPa for Inconel 718) and elongation (15‑30%).

Trade and Export Information - Danyang HB Special Alloy Co., Ltd

China is a major exporter of nickel alloys, and shipments from Jiangsu province frequently target North America, Western Europe, the Middle East and Southeast Asian petrochemical hubs. The HS‑code families 7504‑7508 are monitored under the World Customs Organization’s tariff schedule, and many importing countries require REACH registration and compliance with ISO 9001 quality‑management systems for alloy shipments. Export logistics commonly use 20‑ft or 40‑ft containers packed on wooden pallets, with moisture‑controlled packaging to prevent corrosion during transit. Typical Incoterms are FOB Danyang Port or CIF destination port, and buyers should verify that the shipment includes a mill test report, certificate of conformity and, where required, a third‑party inspection certificate (e.g., SGS, Bureau Veritas).

Sourcing from Danyang HB Special Alloy Co., Ltd - Buyer Guidance

When sourcing from Danyang HB Special Alloy Co., Ltd, request a detailed Mill Test Report (MTR) that lists chemical composition, heat number, mechanical property test results and compliance with the relevant ASTM/ISO standard. Verify the presence of certification such as ISO 9001 or product‑specific AMS/EN certifications; if not supplied, ask the supplier to provide evidence of third‑party testing. Buyers should also confirm packaging details (e.g., double‑wrapped steel bundles, moisture‑proof bags) and ask for a pre‑shipment inspection report to ensure the alloy grade matches the purchase order. Typical minimum order quantities for bulk alloy bars or plates range from 500 kg to 1 ton per grade, with lead times of six to eight weeks from order confirmation, depending on heat availability and export documentation.

What alloy grades does Danyang HB Special Alloy Co., Ltd list with HS codes?

The catalogue includes Hastelloy C‑276 (HS 7507.12), Incoloy 800HT (HS 7304.49), Incoloy 825 (HS 7508.20), Inconel 600 (HS 7505.12), Inconel 625 (HS 7508.90), Inconel 718 (HS 7507.12), Inconel X‑750 (HS 7508.90), Nimonic 75 (HS 7507.20), Nimonic 80A (HS 7507.12), Monel 400 (HS 7504.00) and several others without HS codes listed.

Which international standards are typically applied to the listed nickel alloys?

Common standards include ASTM B575 for Hastelloy C‑276, ASTM B443 for Incoloy 800HT, ASTM B443/B444 for Incoloy 825, ASTM B670 for Inconel 600/625, and AMS 5609/5607 for Inconel 718. ISO 15156 (NACE MR0175) is also referenced for alloys used in sour‑service environments.

What documentation should a buyer request before placing an order?

Buyers should request a Mill Test Report, a Certificate of Conformity referencing the applicable ASTM/ISO standard, and proof of any required REACH registration. If the buyer needs third‑party verification, an inspection certificate from SGS, Bureau Veritas or an equivalent body is advisable.

What are typical packaging and shipping methods for these alloys?

Alloys are usually shipped in 20‑ft or 40‑ft containers, packed on wooden pallets with steel bundles wrapped in moisture‑proof film. Export terms often use FOB Danyang Port or CIF to the buyer’s destination port.

Which regions most frequently import Chinese nickel alloys?

Major import regions include North America (USA, Canada), Europe (Germany, UK, France), the Middle East (UAE, Saudi Arabia) and Southeast Asia (Singapore, Malaysia) where petrochemical and aerospace industries are strong consumers.

What are common lead times and minimum order quantities for these products?

Lead times typically range from six to eight weeks after order confirmation, depending on heat availability. Minimum order quantities are generally 500 kg per alloy grade, though larger orders are common for bulk plate or bar shipments.

Are there any specific certifications buyers should verify for aerospace applications?

Aerospace buyers usually require AMS or ISO certifications, such as AMS 5609 for Inconel 718, along with a full MTR and heat‑treatment records. Compliance with ASME SA‑182 (for forged fittings) may also be necessary for certain component forms.

How can a buyer confirm the alloy’s chemical composition?

The Mill Test Report provides the exact chemical analysis, typically expressed in weight percent for each element (e.g., Ni 72 %, Cr 14‑17 % for Inconel 600). Buyers can cross‑check these values against the relevant ASTM or ISO specification limits before acceptance.
