Material properties

UNS J93503, also known as 25Cr-12Ni heat resistant stainless steel, is a high chromium nickel alloy. It is noted for its excellent resistance to oxidation and corrosion at high temperatures, making it ideal for high-temperature structural applications. This alloy provides good strength and stability in environments up to 1800°F (980°C), and is typically used in conditions where scaling resistance is required alongside high temperature strength.

Advantage

1. Excellent high-temperature strength.
2. Resists oxidation and scaling  at elevated temperatures.
3. Good corrosion resistance in high-temperature environments.
4. Suitable for complex casting applications.
5. Maintains mechanical  properties at high temperatures.

Application

UNS J93503, with its high chromium and nickel content, is particularly valued in environments requiring robust heat and corrosion resistance. This alloy is extensively utilized in the petrochemical industry, especially for constructing components that are exposed to high temperatures and corrosive gases. It is also a preferred material for parts in industrial furnaces and heat treatment plants due to its excellent high-temperature strength and oxidation resistance. Additionally, UNS J93503 finds applications in the manufacturing of components for energy production and processing industries, where materials must withstand harsh conditions while maintaining integrity and performance. This makes it suitable for use in areas such as burner tips, furnace components, and other settings where resistance to thermal degradation is crucial.
