ASTM B753 Ni-Span-C 902 Precision Alloy
ASTM B753 Ni-Span-C 902 Precision Alloy Description
Ni-Span-C 902's properties are highly dependent on heat treatment (aging) and cold working deformation. Common alternative names for Ni-Span-C 902 include 3J53 (China National Standard), Ni-Span C, Alloy 902, UNS K94610, or N09902. ASTM B753 Ni-Span-C 902 Precision Alloy is a stocked product at Lork Group, with a variety of specifications and customer examples available.
When purchasing ASTM B753 Ni-Span-C 902 Precision Alloy bar, we recommend focusing on the following:
1. Clarify performance requirements:
Determine the specific range of the coefficient of thermal expansion (CTE) and the temperature range of constant elastic modulus required for your application. This is key to material selection.
2. Verify materials and standards:
Require suppliers to provide material certification documents (CMTR) that comply with standards such as AMS 5226 or ASTM B753, and verify the chemical composition and heat treatment status.
3. Focus on heat treatment status:
Determine the desired delivery state (e.g., solution-finished for subsequent processing, or aged for direct use) and confirm this with the supplier.
(Lork Group's Purchasing Department and Materials Engineers remind you: When signing the final purchase order, ensure that all standard requirements for heat treatment are met. - Due to this material, customers have experienced the scrapping of products purchased from other suppliers due to failure to meet the heat treatment temperature. This is a special reminder.)
Core Production Process and Price Reference
Ni-Span-C 902 Precision Alloy Production Process
The manufacturing of ASTM B753 Ni-Span-C 902 precision alloy bar is a technology-intensive process that requires extremely high equipment and process control. The core challenges lie in ensuring high material purity, precise dimensional control, and achieving target properties through rigorous heat treatment.
Vacuum Melting：
Vacuum induction melting (VIM) or vacuum induction melting + electroslag remelting (VIM + ESR) processes are used to maximize the removal of gases and impurities, resulting in a high-purity ingot. This is the foundation for subsequent performance.
Aging (a key step):
Performed within a specific temperature range (e.g., 600°C - 750°C) to induce the precipitation of the γ'-strengthening phase (Ni₃(Ti, Al)). Controlling the parameters of this aging process directly determines the material's constant elasticity and low expansion properties.
Finishing and Testing:
Lork Group conducts special testing on materials such as Ni-Span-C 902, including centerless grinding testing to ensure dimensional accuracy, and conducts comprehensive chemical composition, mechanical properties, and non-destructive testing.
