Alloy B4, Hastelloy B-4, DIN 2.4600 Fittings
The Alloy B4 Fittings from Shangdun Special Materials Co.Ltd. are manufactured from Nickel-Molybdenum Alloy UNS N10629 (Hastelloy B-4), a material engineered for superior performance in reducing acid environments. These fittings comply with ASTM B366 and DIN 2.4600 specifications, offering resistance to hydrochloric and sulfuric acids, making them ideal for chemical processing, pollution control, and acid recovery systems. The absence of iron in the composition enhances their corrosion resistance in highly aggressive media.
Hastelloy B-4 is a low-carbon variant of Alloy B, designed to minimize carbide precipitation during welding, which can compromise corrosion resistance. The alloy’s typical composition includes Ni as the balance, Mo at 26-30%, and trace amounts of other elements. Standard forms include elbows, tees, reducers, and caps, with dimensions and wall thicknesses tailored to pressure and flow requirements. The fittings are produced via forging, followed by heat treatment to achieve the desired mechanical properties and microstructure.
These fittings are sourced by industries such as chemical manufacturing, wastewater treatment, and oil refining, where reliability in corrosive environments is non-negotiable. Shangdun Special Materials Co.Ltd. is based in Shisheng Industrial Park, Jiaxing, a region known for its specialty metal production. Buyers should confirm the fittings’ compliance with project-specific standards, such as ASTM B366 for forged fittings, and request details on ultrasonic testing (100% per ASTM E2375) to ensure defect-free components.
| Material Grade | Nickel-Molybdenum Alloy UNS N10629 (Hastelloy B-4), DIN 2.4600 |
| Standard Specifications | ASTM B366, DIN 2.4600 |
| Primary Application | Reducing acid environments (hydrochloric, sulfuric acids) |
| Typical Tensile Strength | standard 830 MPa (120 ksi) for annealed condition |
| Typical Yield Strength | standard 380 MPa (55 ksi) for annealed condition |
| Typical Elongation | standard 40% in 50mm (2 in) |
| Typical Hardness | standard 220 HB max (Brinell) |
| Carbon Content | standard ≤0.01% (low-carbon variant) |
| Density | standard 9.22 g/cm³ |
| Corrosion Resistance | Excellent in reducing acids; resistant to pitting and stress corrosion cracking |
Shangdun Special Materials Co.Ltd. operates from Shisheng Industrial Park in Jiaxing, Zhejiang Province, China, a region with a strong focus on specialty metals and industrial components. The company specializes in high-performance alloy fittings, including Hastelloy B-4, catering to demanding sectors such as chemical processing and pollution control. Its location provides access to advanced manufacturing facilities and a skilled workforce for producing precision-engineered components.
The supplier’s trust tier is classified as harbor, and while response rate data is not provided, its product offerings align with the technical requirements of industries handling aggressive media. There are no stated certifications, operational histories, or client references in the listing, so buyers should directly request evidence of quality control, such as 100% ultrasonic testing per ASTM E2375, and compliance with relevant standards like ASTM B366 for forged fittings.
Hastelloy B-4 (UNS N10629) fittings manufactured to ASTM B366 and DIN 2.4600 specifications offer superior resistance in reducing acid environments including hydrochloric and sulfuric acids. These nickel-molybdenum alloy forged fittings are widely used in chemical processing, pollution control equipment, and acid recovery systems. As a specialized industrial commodity, pricing varies significantly by size, schedule, and quantity ordered, with major origins from the USA, Germany, and Japan for critical applications.

Sourcing Alloy B4 Fittings from Shangdun Special Materials Co.Ltd. - China Import Guide
Before placing an order with Shangdun Special Materials Co.Ltd., verify the material composition and mechanical properties against UNS N10629 and DIN 2.4600 standards. Request copies of the material test certificates (MTCs) and ultrasonic test reports to confirm compliance with ASTM B366 and ASTM E2375. For critical applications, such as pollution control systems, ensure the fittings meet project-specific pressure and temperature ratings to avoid premature failure.
Clarify lead times, which may vary based on the size, schedule, and quantity of fittings required. Standard lead times for specialty alloy fittings can range from 6 to 12 weeks, depending on raw material availability and production capacity. Discuss Incoterms (e.g., FOB Jiaxing or CIF destination) and payment terms (e.g., T/T with a 30% deposit) to align with your procurement processes. Confirm packaging methods, such as wooden crates or pallets, to prevent damage during transit.
Upon receipt, inspect the fittings for dimensional accuracy, surface finish, and material consistency. Use calibrated tools to verify dimensions against ASTM B366 tolerances, and check for visible defects or irregularities. Conduct a hydrostatic test or request a sample for laboratory analysis to validate corrosion resistance in your specific environment. Ensure all documentation, including MTCs, test reports, and compliance certificates, is complete and matches the supplied materials. Address any discrepancies with the supplier before installation.
