1.4886 Heat Resisting Austenitic Steel

1.4886 Heat Resisting Austenitic Steel is a high-performance stainless steel alloy designed for applications requiring excellent resistance to oxidation and high-temperature corrosion. With a balanced composition of chromium, nickel, aluminum, and silicon, 1.4886 maintains its mechanical strength and structural stability at continuous operating temperatures up to 1050°C. Its fully austenitic microstructure ensures superior toughness, thermal fatigue resistance, and durability in harsh industrial environments. Commonly supplied in bars, plates, tubes, and sheets, this alloy is ideal for furnace components, heat exchangers, high-temperature exhaust systems, and chemical processing equipment. Reliable, heat-resistant, and easy to fabricate, 1.4886 is a preferred choice for industries demanding long-term high-temperature performance.

1.4886 stainless steel is widely used in high-temperature industrial furnaces, heat exchangers, and chemical processing equipment. It is ideal for furnace trays, tubes, exhaust systems, and combustion components due to its excellent oxidation and sulfur resistance. Its fully austenitic structure ensures high-temperature strength, thermal fatigue resistance, and long-term durability in harsh environments.
