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

大多数常见的不锈钢成型方法都可用于 2507 的冷加工。与奥氏体钢相比，这种合金的屈服强度较高，延展性较低，因此制造者可能会发现有必要提高成形力、增加弯曲半径并增加回弹余量。与奥氏体不锈钢相比，在 2507 上进行深拉、拉伸成形和类似加工更为困难。当成型需要超过 10% 的冷变形时，建议进行固溶退火和淬火。.

热处理

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.
