Stainless Steel 17-7 PH Sheets and Plates are a type of precipitation-hardening stainless steel, primarily made up of about 17% Chromium and 7% Nickel, with some Aluminum added to enhance hardening. This alloy delivers impressive tensile strength, typically ranging from 960 to 1,100 MPa, along with outstanding spring-like properties after heat treatment. It maintains solid mechanical performance across a wide temperature range. Additionally, 17-7 PH shows moderate corrosion resistance, making it suitable for both atmospheric and mild chemical environments. Its excellent formability and stability during thermal processing further enhance its versatility.
