Processing
Hot Forming
2507 should be hot worked between 1875 F and 2250 F. This should be followed by a solution anneal at 1925F minimum and a rapid air or water quench.
Cold Forming
Most of the common stainless steel forming methods can be used for cold working 2507. The alloy has a higher yield strength and lower ductility than the austenitic steels so fabricators may find that higher forming forces, increased radius of bending, and increased allowance for springback are necessary. Deep drawing, stretch forming, and similar processes are more difficult to perform on 2507 than on an austenitic stainless steel. When forming requires more than 10% cold deformation, a solution anneal and quench are recommended.
Perlakuan panas
2507 should be solution annealed and quenched after either hot or cold forming. Solution annealing should be done at a minimum of 1925 F. Annealing should be followed immediately by a rapid air or water quench. To obtain maximum corrosion resistance, heat treated products should be pickled and rinsed.
