1Cr20Ni14Si2 Stainless Steel Composition & Heat‑Resistant Properties

1Cr20Ni14Si2 is a heat‑resistant austenitic stainless steel specified in GB/T 4237 and GB/T 4238. With approximately 20% chromium, 14% nickel, and 2% silicon, it offers excellent oxidation resistance and thermal stability at elevated temperatures.

The grade is widely used in industrial furnaces, heat‑treatment equipment, combustion systems, exhaust assemblies, and high‑temperature structural components. It maintains good mechanical properties and microstructural stability under repeated thermal cycling conditions.

1Cr20Ni14Si2 is supplied as sheets, plates, tubes, bars, and strips. It is commonly used in petrochemical plants, metallurgy, thermal processing facilities, and industrial furnace construction.
