Inconel alloys have nickel as their base element, which improves the performance of Inconel 625 Seamless Pipe at elevated temperatures. Inconel 625 is an alloy that also performs well at lower temperatures. A change in temperature causes alloyed pipes to expand or contract.
China made Nickel Alloy N06625 Welded Pipe & ASTM B444 Inconel 625 Pipes With good mechanical strength at elevated temperatures, alloy 625 is known as a high temperature alloy. Inconel alloys have nickel as their base element, which improves the performance of Inconel 625 Seamless Pipe at elevated temperatures.
Alloy 625 is a nickel based alloy that offers flexible weldability and incredible corrosion resistance that is suitable for many different industrial applications. It has been specifically engineered to be used in some of the world’s most demanding conditions. The alloy is used in a variety of fields such as chemical processing, aerospace engineering, marine engineering, pollution control and even nuclear reactors.

Seamless and Welded
Alloy 625 provides the perfect mix of corrosion resistance and strength. When oxidation is a concern, it provides good resistance up to temperatures of 1093°C. Due to the nickel content, it’s virtually immune to corrosion by chloride as well, which is why it’s used in many seawater applications and also chemical processing. If you need to use Alloy 625 pipes with hazardous materials or extreme temperatures, it can withstand the punishment and retain its shape, giving you confidence in its ability.
Alloy 625 is also incredibly resistant to extreme temperatures. Compared to most varieties of steel, alloy 625 does not lose tensile strength at extreme temperatures, making it one of the most temperature-tolerant materials that can be used in industrial applications such as heat treatments thanks to its ability to hold its shape despite the temperatures. This is what makes it such a suitable material for jet engines, but it’s not just heat that Alloy 625 can withstand. Even in environments where the alloy is exposed to extremely cold temperatures, Alloy 625 strengthens itself faster than stainless steel to become tougher and easier to work with.
Despite all of these incredible advantages, Alloy 625 still manages to have good welding capabilities and can be shaped and formed to your needs. In short, if you’re looking for a material that can withstand extreme temperatures both hot and cold, is still flexible enough to be shaped to your needs and can even resist corrosion in seawater, then Alloy 625 is the perfect material for your needs. It might be an expensive material, but as one of the toughest metals available in the industry and the countless applications for its use, it’s worth the cost
We manufacture Inconel 625 seamless pipe & tube strictly according to ASTM B444. Inconel 625 has high strength, which makes the cold rolling process of seamless pipe & tube more difficult. We have a complete seamless pipe & tube production line, which can fully guarantee the quality of pipes. In addition, we do a complete hydrostatic test on all pipes. If you have requirements for the grain size of the material, we can also meet your requirements.
