Due to its exceptional properties, Inconel 625 is considered an invaluable material for engineers and industries dealing with extreme operating conditions.
If you’re considering purchasing Inconel 625 round bars in India, understanding the pricing structure is essential. This blog will provide an overview of the factors that influence the price of Inconel 625 round bars, the typical price range, and how to source the best material for your needs.
What is Inconel 625?
Inconel 625 is a nickel-chromium-molybdenum alloy with a high concentration of nickel (58–72%) and smaller amounts of chromium (20–23%) and molybdenum (8–10%). This combination of elements provides excellent resistance to oxidation and corrosion, particularly in extreme environments such as high-temperature and chemical exposure.
Key Features of Inconel 625:
-
High Temperature Resistance: Inconel 625 can perform well at temperatures up to 980°C in oxidizing conditions, making it ideal for use in high-heat environments.
-
Corrosion Resistance: The material is highly resistant to acids, salts, and other aggressive substances, making it suitable for marine environments and chemical industries.
-
Strength: Inconel 625 maintains its strength at elevated temperatures, making it suitable for applications involving mechanical stress.
-
Weldability: It has excellent weldability and is often used in fabrication, which is vital for many industrial applications.
-
Fatigue and Stress-Corrosion Resistance: The alloy can withstand cyclic stresses and exposure to corrosive elements, reducing the risk of structural failure in extreme conditions.
Factors That Affect the Price of Inconel 625 Round Bar in India
The price of Inconel 625 round bar in India can fluctuate based on several factors. Understanding these can help you make an informed purchase decision.
1. Size and Dimensions of the Bar
The diameter and length of the Inconel 625 round bar significantly impact its price. Larger diameter bars and those with custom lengths will usually command higher prices due to the additional material required and the complexity of manufacturing.
-
Standard Sizes: Round bars typically range from 6mm to 150mm in diameter, but custom sizes may be available on request.
-
Length: The standard length for round bars is generally 3 meters or 6 meters, but customers can often request specific lengths depending on their project requirements.
-
Finish Type: The finish, whether hot-rolled, cold-drawn, or polished, will also influence the cost. Bars with polished surfaces are generally more expensive due to the additional processing steps.
2. Grade and Alloy Standards
Inconel 625 round bars conform to various international standards and grades. The specific grade you require—such as ASTM B446, NACE, or others—can affect the price. Higher-grade materials, which provide stricter performance requirements and enhanced mechanical properties, typically come with a higher price.
3. Supplier and Mill Origin
-
Domestic vs. Imported: Inconel 625 round bars manufactured within India may be priced differently from those imported from countries like the US, Japan, or Europe. Imported bars often come with additional import duties, taxes, and shipping charges, making them more expensive.
-
Reputation of the Supplier: Reputable suppliers who provide certified material (Material Test Certificates or MTC) and offer warranties on their products often charge a premium for the assurance of quality and reliability.
4. Bulk Purchases
Purchasing Inconel 625 round bars in large quantities or as part of a long-term supply agreement typically results in lower pricing per kilogram. Bulk orders often allow suppliers to offer competitive pricing, as they reduce logistical costs and ensure economies of scale.
5. Market Demand and Raw Material Prices
The prices of raw materials used to make Inconel alloys—such as nickel, chromium, and molybdenum—directly influence the price of the round bars. Nickel, in particular, is subject to market fluctuations due to its global supply chain, and as its price rises, the cost of Inconel 625 also increases.
What is the Typical Price Range for Inconel 625 Round Bar in India?
As of 2024, the price of Inconel 625 round bars in India typically ranges between:
-
₹3,500 to ₹6,500 per kg
This range can vary based on several factors, including those mentioned above. It’s important to note that the price may change depending on:
-
The specific supplier
-
Whether the product is imported or locally produced
-
The quantity being ordered
-
The specific grade or certification required for the project
Note: Prices tend to be higher for larger-diameter bars, bars with specific finishing, or imported stock, while smaller, standard-sized bars may be more affordable.
Industries That Use Inconel 625 Round Bars
Inconel 625 is indispensable in industries where materials face extreme conditions. Some of the primary industries that rely on Inconel 625 round bars include:
