17-7 Stainless Steel is a good corrosion resistant PH grade stainless. This grade is a higher strength and hardness stainless with superior fatigue properties, good formability and minimal distortion upon heat treatment. 17-7PH is used widely in aerospace applications. To achieve the highest mechanical properties this material would be cold worked to condition C and then heat treated.
