Packaging of Hastelloy N Round Bar:

Shanghai Metal Products are packed and labeled according to the regulations and customer's requests. Great care is taken to avoid any damage which might be caused during storage or transportation. In addition, clear labels are tagged on the outside of the packages for easy identification of the product I. D. and quality information.

1) Shanghai Metal Standard

2) Customization


Q1.How long does sample preparation take?

A: Stock sizes: 5–7 working days. Custom diameters or nuclear-grade VIM+ESR material: 25–35 working days.

 

Q2.What information do you need for a quotation?

A: Section shape (round / square / hex), diameter or across-flat size, length, quantity, condition (solution-annealed or cold-finished), surface (peeled / ground / turned), required NDE level, and destination port.

 

Q3.What is the MOQ and lead time?

A: MOQ is 100 kg for commercial grades and 500 kg for VIM+ESR nuclear-grade material. Standard orders ship in 20–30 working days; customized or nuclear-grade orders take 35–50 working days.

 

Q4.What standards and certifications are available?

A: Bars are supplied per ASTM B335 / ASME SB-335 and project-specific MSR specifications, with MTC EN 10204 3.1 or 3.2, including chemical composition, mechanical properties and ultrasonic test reports.

 

Q5.Why use Hastelloy N instead of 316H or Inconel 600 in molten fluoride service?

A: 316H suffers rapid intergranular attack and chromium depletion in molten fluorides above 600°C, and Inconel 600 forms unstable fluoride scales. Hastelloy N was specifically developed for LiF-BeF2-ZrF4 service and shows corrosion rates orders of magnitude lower.

 

Q6.What condition should the bar be supplied in for reactor welding?

A: Solution-annealed at 1175°C and water-quenched, with peeled or ground surface. After welding, the component should receive the same 1175°C water quench to dissolve weld-zone carbides and restore corrosion resistance.

 

Q7.Is Hastelloy N suitable for chlorides or seawater?

A: It is only moderately resistant. Its Mo content (about 7%) is much lower than C-276 (16% Mo), so it is not recommended for pitting-critical seawater or chloride service; use a higher-Mo alloy in those cases.
