17-4Ph Stainless Steel Plate Sheet
The martensitic, precipitation-hardening stainless steel known as 17-4 PH Sheet Plate (AMS 5604) contains chromium, nickel, and copper in addition to the standard stainless steel elements. The combination of 17-4 stainless steel's high strength, strong corrosion resistance, and toughness in base metals and welds makes it a beneficial material.
