Heat Resistant Stainless Steel Pipe

Heat Resistant Stainless Steel Pipe is a high-performance alloy pipe designed to maintain structural stability,mechanical strength,and oxidation resistance under prolonged high-temperature environments.By adding high contents of chromium,nickel,silicon,niobium,and other alloying elements,it forms a dense and stable oxide film on the surface,effectively resisting scaling,creep deformation,and high-temperature corrosion.It is widely used in high-temperature fluid and gas transmission in industrial furnaces,boilers,petrochemical facilities,and power generation equipment.

Key Features

Excellent high-temperature oxidation resistance and thermal stability

Strong resistance to creep and stress rupture at elevated temperatures

Good mechanical properties at both high and room temperatures

Outstanding corrosion resistance to high-temperature gases and media

High weldability and formability for reliable fabrication and installation

Long service life with low maintenance under harsh thermal conditions

Common Grades

304H:Heat-resistant grade with higher carbon content,suitable for general high-temperature applications

316H:Molybdenum-bearing,better high-temperature corrosion resistance than 304H

321:Stabilized with titanium,excellent resistance to intergranular corrosion after heating

347:Stabilized with niobium,ideal for frequent high-temperature cycling

310S(2520):High chromium-nickel austenitic stainless steel,usable up to 1150°C,for extreme high-temperature conditions

Main Applications

Boiler tubes,furnace pipes,heat exchanger tubes

Petrochemical cracking tubes and high-temperature pipelines

Flue gas ducts,incinerator piping,thermal power plant systems

Industrial heating equipment,kilns,and high-temperature conveying pipelines

Automotive exhaust systems and engine components
