Mitchell Stainless, a trusted manufacturer and supplier in Hamilton, New Zealand, provides premium Stainless Steel 17-4 PH coils, engineered for high-strength and corrosion-resistant applications. This precipitation-hardening stainless steel offers excellent tensile strength, hardness, and durability after heat treatment, making it ideal for aerospace, chemical, and industrial applications. Mitchell Stainless ensures each coil meets strict quality standards, providing uniform thickness, smooth surface finishes, and consistent mechanical performance. 17-4 PH coils are designed for precision forming, fabrication, and manufacturing processes, delivering reliable and long-lasting components capable of performing under demanding mechanical and environmental conditions.
Stainless Steel 17-4 PH coils are composed primarily of iron, with 15–17% chromium, 3–5% nickel, 3–5% copper, and small amounts of manganese, silicon, and carbon. This alloy provides high tensile strength, excellent hardness, and good corrosion resistance after precipitation hardening. Chromium and nickel ensure toughness and oxidation resistance, while copper enhances hardness and mechanical performance. These coils maintain superior strength, durability, and dimensional stability, making them suitable for critical structural, mechanical, and high-stress applications.
