Product information

Grade: Haynes HR-160
Origin: USA

Haynes HR-160 is a nickel-cobalt-chromium-silicon solution-strengthened high-temperature alloy. Its unique high-silicon composition forms a double-layer protective oxide film, giving it top-notch resistance to high-temperature sulfide, carburization, chlorine-containing flue gas, and molten vanadium salt corrosion. It can withstand temperatures up to 1204°C for long periods, with excellent high-temperature creep resistance. Its cold and hot bending, as well as welding performance, are stable. For many years, it has been widely used in demanding high-temperature corrosion environments such as waste incineration heat recovery boilers, paper mill alkali recovery furnaces, gasification units, cement rotary kilns, heat treatment radiant tubes, and sulfur recovery equipment.

Product parameter

Chemical Composition

Nickel (Ni) is the main component of Haynes HR-160 alloy, present in the remainder amount, stabilizing the austenitic matrix and providing high-temperature toughness and basic corrosion resistance. 
Cobalt (Co) content ranges from 29.00% to 33.00%, strengthening the matrix through solid solution and greatly enhancing resistance to sulfidation and high-temperature creep strength. 
Chromium (Cr) content is between 28.00% and 30.00%, forming a dense chromium oxide layer that resists high-temperature oxidation and sulfidation attack. 
Silicon (Si) content is 2.50% to 3.00%, creating an inner silica protective layer that blocks sulfur and chlorine from penetrating. 
Iron (Fe) content does not exceed 3.00%, strictly controlling impurities to avoid weakening high-temperature corrosion resistance. 
Carbon (C) content is no more than 0.10%, with trace carbon strengthening grain boundaries while low carbon suppresses welding intergranular corrosion. 
Manganese (Mn), Phosphorus (P), Sulfur (S), and Boron (B) do not exceed 1.00%, 0.030%, 0.015%, and 0.005% respectively, strictly limiting impurities to ensure long-term high-temperature stability.

Mechanical Properties

Tensile Strength: 735 MPa, indicating the maximum pull force the material can withstand. 
Yield Strength: 305 MPa, the force at which the material begins to deform permanently. 
Elongation: 50%, showing how much the material can stretch before breaking, making bending and stamping less likely to crack. 
Hardness: 215 HB, the material’s resistance to surface indentation, with easier machining in the annealed state. 
Fatigue Strength: maintains stable fatigue life under high-temperature sulfur and chlorine alternating heat environments, resisting fatigue cracks during long-term thermal cycling. 
Elastic Modulus: 208 GPa, reflecting the material's stiffness; it deforms less under high-temperature stress, ensuring strong dimensional stability for furnace components.
