With state-of-the-art manufacturing facilities, rigorous quality control measures, and a team of skilled technical professionals, Walid Stainless guarantees that their products adhere to international standards. Their Stainless Steel 17-7 PH Coils are extensively supplied to industries such as aerospace, automotive, electronics, and precision engineering, ensuring consistent quality, precise dimensions, reliable performance, timely delivery, and dedicated customer-focused technical support around the globe.
Stainless Steel 17-7 PH Coils are a type of precipitation hardening stainless steel, enriched with chromium, nickel, and aluminum. The typical chemical makeup consists of about 16–18 percent chromium and 6.5–7.75 percent nickel, along with aluminum additions that facilitate effective precipitation hardening. Mechanically, these coils boast high tensile and yield strength, excellent fatigue resistance, good toughness, and dimensional stability after heat treatment. They also offer solid corrosion resistance and formability in the solution-treated state, making them perfect for high-performance applications that demand both strength and flexibility.
