Stainless steel About 16–18% chromium, 6.5–7.75% nickel, 0.75–1.5% aluminium, and a maximum carbon content of 0.09% make up 17-7 PH pipes. The goal of this precipitation-hardening alloy is to provide exceptional strength and hardness while preserving strong corrosion resistance. Depending on heat treatment, these pipes usually have a tensile strength of up to 1310 MPa, a yield strength of about 1170 MPa, and an elongation of 6–10%. Because of their exceptional fatigue resistance and low post-formation distortion, 17-7 PH pipes are appropriate for high-pressure, high-stress, and precision-driven applications.
