Inconel 713C Nickel Alloy Bar
Inconel 713C Nickel Alloy Bar Description
Half of the Inconel 713C nickel alloy bar supplied by Lork Group is in black bar form (suitable for testing material composition). If performance requirements are to be met and put into use, solution aging heat treatment is generally required. Inconel 713C nickel alloy is also known as INCO 713C or 713C, K418 (Chinese designation, also known as K18 or 518), and GH4413 (corresponding to black bar billet).
When purchasing Inconel 713C bar, Lork Group's materials engineers recommend considering the following:
1. Determine your needs and form:
First, determine the product form you require. Inconel 713C is primarily a cast alloy. It may be supplied in the following forms:
Cast bar: As-cast bar or parts obtained directly through methods such as investment casting.
Master alloy bar: Used for remelting and pouring castings.
"Black bar" (hot-worked): Bars obtained after hot rolling or forging, with a surface oxide scale, are often used as tube billets or other billets requiring further hot processing (such as hot extrusion or piercing).
Select the appropriate form based on your subsequent processing flow and end use.
2. Confirm Materials and Standards:
When purchasing, clearly specify that materials comply with relevant standards (such as China's YB/T5248-93) and require suppliers to provide material certification to ensure acceptable chemical composition and mechanical properties..
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.
Core Production Process and Price Reference
Inconel 713C Nickel Alloy Production Process
The production of Inconel 713C nickel alloy bar is a technology-intensive process, requiring extremely high standards of equipment and process control.
Melting and Refining:
Vacuum Induction Melting (VIM) is typically used to precisely control the alloy composition and effectively remove gases and impurities. To further enhance material purity and uniformity, secondary refining processes such as electroslag remelting (ESR) or vacuum autoclave remelting (VAR) are often employed.
Bar rolling:
The billet after forging is heated again to the hot working temperature range and gradually rolled into a bar of the required diameter through multiple hot rolling passes. During the high-temperature rolling process, an oxide scale will naturally form on the surface, which is often called "black bar".
Heat treatment:
Solution treatment: For example, at approximately 1180°C, this dissolves the strengthening phases and prepares for subsequent aging. Aging treatment: For example, at approximately 930°C, this allows for the uniform dispersion and precipitation of fine γ' strengthening phases, achieving peak strengthening. This alloy can also be used directly in the cast state.

Forging:
Large-sized Inconel 713C Nickel Alloy ingots are heated to a suitable temperature (e.g., 1100°C - 1150°C) and forged by free forging or rapid forging with multiple passes and large deformation. The core goal is to break up the coarse cast structure, refine the grains, weld together internal defects, and provide a uniform initial billet for subsequent rolling.
