40 Years of Experience in Special Alloy Manufacturing
When your stainless steels start to soften scale or lose spring force in high temperature environments, then you definitely should choose high temperature alloy. High temperature alloys possess creep resistance, oxidation resistance, hot corrosion and thermal cycling stability not only room temperature corrosion performance. So high temperature alloy is your safest choice. SparkX provides high temperature alloy like rods, wires, strips, plates and coils that meet all your required specifications. We can also match heat treatment conditions, finish treatments and TÜV certified EN 10204 3.1. Typical grades we provide for this category include Inconel 718, Inconel X 750, Nimonic 80A and Nimonic 90, so please free to contact us if you have any other requirements.
Multiple Grades of High Temperature Alloys
If you have any other needs or require customization, please feel free to contact us.
Precipitation hardening nickel alloy, suitable for high temperature springs, fasteners and has excellent relaxation and oxidation resistance.
High strength nickel alloy has excellent fatigue and creep resistance, withstanding temperatures up to 700℃, ideal for key super high temperature parts.
Age-hardening alloy, optimized for creep strength and stress fracture properties at high temperatures, it’s always used for turbine blades and turbine disks.
Heat treatable nickel alloy has excellent oxidation resistance and high temperature strength, commonly used in fasteners, springs and valves.
Why High Temperature Alloy Not Stainless Steel
For high temperature parts the real question is not whether they will corrode, but also whether they can maintain their shape and load-bearing capacity at high temperatures. Especially these applications such as gas turbines, fuel nozzles, heat treatment fixtures and furnace linings, these must be able to withstand high temperatures, extremely oxidizing conditions and repeated use. Many malfunctions come from creep deformation relaxation of spring force oxidation scale spallation and thermal fatigue cracking during start stop cycles. SparkX provides high temperature alloy to reduce these malfunctions so your equipment can maintain its tolerances, sealing force and strength over a long service life. If your application involves continuous high temperature loads, frequent thermal cycling or corrosive high temperature gases, then choose SparkX high temperature alloys is absolutely the right choice.
Furnace Route of High Temperature Alloys
Even some high temperature alloy are the same materials, their performance can still much different. Because different furnace temperature controls can significantly affect the performance of high temperature alloys. SparkX decides the melting and heat treatment processes based on the grade and application, choose the appropriate melting processes such as vacuum melting, electroslag remelting, vacuum arc remelting and others. This is very important, the suitable melting process can significantly reduce impurities in your high temperature alloy and ensure the accuracy of the chemical composition. Each batch of material is tracked by furnace number and retained records, so the microstructure and performance you verify as same as you receive in production.
Reproducibility of High Temperature Alloys
High temperature alloys are very sensitive to heat treatment conditions and process parameters, so their reproducibility is extremely important. SparkX through established process routes, retained inspection records and traceability compliant with EN 10204 3.1. During the engineering review phase, we can adjust the sampling plan for chemical composition, mechanical properties and corrosion and oxidation related inspections as needed. SparkX ensures consistency for each batches through a stable manufacturing process and matches the appropriate delivery condition to your downstream processes such as machining, forming, spring manufacturing. If you are sourcing high temperature alloys for your new project, SparkX can provide samples and collect initial production feedback, and we can stable production based on the same process route. This is especially important for heat treated springs, fasteners and high temperature components.
We need some commonly information such as service temperature range, temperature holding time, duty cycle, load type, creep or stress relaxation, environmental description, target product shape, dimensions, standards and any required subsequent heat treatment conditions.
Different nickel and cobalt content, grades, forms, sizes, yields and heat treatments and inspection scopes have different prices. The best cost control is not only negotiating high temperature alloy price but choose the right form and condition to cut machining time scrap and rework after heat exposure.
Of course we can. SparkX can production trial for tooling and process validation, and ensure a stable route for production. We both supply the traceability EN 10204 3.1 certified by TÜV. If you need we can also additional third party inspections, but you will need to pay the extra costs.
Inconel 718 is often used in applications where high strength is required even after precipitation hardening. Inconel X 750 is commonly use for springs and fasteners that require strength retention at high temperatures. Nimonic 80A is a reliable high temperature alloy with excellent oxidation resistance. If you need to improve creep and thermal fatigue limits to meet long time service, Nimonic 90 is a good choice. Please send us your requirements and applications and we will provide you the best solution.
