Committed to excellence, Aaron ensures that each product meets stringent standards, making it desirable for customers around the world.
Stainless steel 17-4 PH angle is a precipitating alloy consisting mainly of iron, chromium (15–17%), nickel (3–5%), and copper (3–5%), as well as elements such as niobium in small amounts. This alloy combines high strength with excellent corrosion resistance, especially in seawater, chemical and high temperature conditions. Its mechanical properties include tensile strength of 100–160 ksi (690–1100 MPa), yield strength of 90–120 ksi (620–830 MPa), good hardness from 35 to 45 HRC Commonly used in aerospace, petrochemical and military applications due to durability and resistance to stress corrosion cracking occurs .
