Ferritic Oxidation-Resistant Steel:
Grades like 1Cr13Si2, 1Cr18Si2, and 1Cr25Si2 are rich in chromium and silicon, offering excellent oxidation resistance but not suited for impact loads. Ideal for temperatures ranging from 800ยฐC to 1000ยฐC, commonly used in furnace components such as heater hangers and nozzles.
Austenitic Oxidation-Resistant Steel:
Grades such as Mn18A15 and 3Cr18Mn12Si2N are capable of operating at temperatures between 850ยฐC and 1200ยฐC. These steels are frequently used in pipes for the petroleum and chemical industries, such as heating furnace tubes. They also offer good welding properties and high-temperature strength.
Fe-Al-Mn Series Heat Resistant Steel:
This category includes alloys with added aluminum, manganese, silicon, titanium, and rare earth elements, enhancing oxidation and carburization resistance. These steels are more cost-effective than Cr-Ni austenitic heat resistant steels and are suitable for environments exceeding 900ยฐC, commonly used in heat treatment furnace components.
Exceptional High-Temperature Performance:ย Maintains stability at temperatures ranging from 600ยฐC to 800ยฐC, making it ideal for various heat treatment processes.
Superior Physical Properties:ย Enhanced resistance to creep and oxidation due to special alloy compositions and heat treatment processes.
Strong Chemical Stability:ย Alloy elements such as chromium, nickel, and molybdenum enhance stability in corrosive environments.
Excellent Workability:ย Despite being a high-strength material, heat resistant steel can be processed and formed using conventional metalworking methods.
Versatile Applications:ย Available in various types, making it suitable for multiple industrial sectors, including energy, automotive, and aerospace.
Due to its unique properties, heat resistant steel is widely used in the following industries:
Boilers and Pressure Vessels:ย Essential for manufacturing key components that must withstand high pressure and high temperature.
Automotive Industry:ย High-performance heat resistant steel is used in the production of exhaust systems and turbochargers.
Aerospace:ย In the aerospace sector, it is utilized in the production of engine components and thermal barrier systems.
Energy Sector: Plays a crucial role in traditional coal-fired power plants, waste incineration plants, and nuclear power plants.
Petrochemical Industry:ย Used in the manufacturing of pipelines, reactors, and other equipment in oil refining and chemical production.
Our heat resistant steel products come in various standard sizes, with customization options available to meet specific needs.
Length Range:ย Typically 1000mmย to 7000ย mm, with custom lengths available upon request.
