What is Nickel-Based Superalloy K403

As the world deals with potential supply shortages, oil prices are soaring again, with more dramatic spikes and sudden drops expected.

For consumers, that means more expensive gas for longer - prices at the pump remain above $4 a gallon. For the economy, that means more inflation. In addition to the pressure on consumers, any business that relies on oil -- from airlines and truck drivers to chemical companies and plastics producers -- will face higher costs.

Mr Pickering estimates that 2m to 3m barrels a day of Russian oil shipped by water are frozen out of the market with no direct buyers. Due to the soaring oil price, the price of the Alloy K403 in the chemical industry will also

 be greatly affected. He said China and India are continuing to buy Russian crude. "I'm sure there will be others willing to take on more over time," he said. Mr Pickering said he did not expect oil to return to $130 a barrel, but added that it could happen. West Texas Intermediate for April settled 7% higher at $112.12 a barrel on Monday.

Francisco Branch, head of commodities and derivatives at Bank of America, said the US market was ready for cyclical price spikes and price swings in the product name.

What is K403 alloy?

Alloy K403 is a cast nickel-based superalloy. The alloy has high high temperature strength and is widely used for casting guide vanes and working blades of turbojet, turbopulder, turboshaft and turbofan series engines. The γ' phase is the main strengthening phase of nickel-based alloys and affects the high temperature properties of the alloys. The K403 alloy has a higher content of γ' phase forming elements Al, Ti, etc., so the volume fraction of the γ' phase in the alloy structure is higher.

Solution treatment of K403 alloy

1. After the alloy undergoes incomplete solution treatment at 1140 and 1180 °C, the microstructure is γ' phase of two sizes; after complete solution treatment at 1210 °C, air-cooled, 0.2 μm γ' phase is uniformly precipitated. With the increase of the solution temperature, the primary γ' phase gradually decreases, and the dendrite structure becomes inconspicuous.


2. For the alloy after solution treatment at 1190 ℃ for 4h, the size of γ' phase particles changes little after aging at 900, 940 ℃ for 16h, but the distribution is more uniform; after aging at 980 ℃ for 16h, the particle size of γ' phase decreases It became larger to 0.3-0.6 μm, and the shape changed from square to irregular, nearly circular. After aging, the tensile properties and hardness of the alloy are improved.


3. The alloy obtained the relative maximum tensile strength and room temperature hardness after aging at 940℃. The recommended heat treatment process for K403 alloy is 1190 ℃, 4h, AC+ 940 ℃, 16h, AC.
