17-7 is a precipitation hardening, chromium-nickel-aluminum steel, characterized by high strength and being moderately resistant to corrosion.
In general, 17-7’s corrosion resistance is similar to 304 stainless steel and the alloy is known for its ability to withstand high temperatures.
17-7 can be strengthened through heat treatment and is commonly used for extremely detailed, intricate parts due to its low distortion in heat treatment.
17-7’s high strength and hardness, in addition to excellent fatigue properties and good corrosion resistance make it perfect for applications in aerospace as well as for washers, springs, blades, pressings, and encapsulated bellows.
