The chemical composition analysis of 2304 is ideal after solution annealing treatment at 950°/1050°C(1742°/1922°F) to obtain the microstructure of 50α / 50γ.
The microstructure of 2304 is more stable than that of the duplex stainless steel containing molybdenum.
Intermetallic phases do not appear until 10 hours of placement in the temperature range of 750°/850°C (1382°/1562°F).
After heat treatment in the 350°/500°C (662°/932°F) range, the copper element in 2304 alloy increases the hardness of the steel.
Hot forming
Hot forming must be performed in the temperature range of 1150/900°C(2100/1650°F).
After forming, solution annealing treatment is recommended in the temperature range of 950°/1050°C(2100°/1650°F) to restore the corrosion resistance and mechanical properties.
Care must be taken during heating to avoid creep of the product.
Cold forming
Cold forming of 2304 alloy is not difficult.
The 304L and 316L cold forming equipment is also suitable for the 2304.
Due to its high mechanical properties, including yield strength, high pressure is required during cold forming.
Finally, the solution annealing treatment is recommended to restore the mechanical properties and corrosion resistance, which is the same as hot forming.
derusting
The solution and paste used are the same as 304L/316L.
Due to its corrosion resistance, pickling time is slightly longer than the austenite grade.
machinability
When drilling,2304 duplex stainless steel shows stronger machinability.
Its performance is comparable to 316LEZ*.
En outre,2304 corrosion resistance and cleanliness is stronger.
The local corrosion resistance is also improved.
