Mitchell Stainless, a trusted manufacturer and supplier in Hamilton, New Zealand, provides high-quality Stainless Steel 17-7 PH tubing designed for high-strength and corrosion-resistant applications. This precipitation-hardening alloy offers excellent mechanical properties, including high tensile and yield strength, combined with good corrosion resistance. 17-7 PH tubing is precision-engineered for consistent dimensions, smooth surface finish, and reliable performance under demanding industrial conditions. Mitchell Stainless ensures that each tube meets strict quality standards, making it ideal for aerospace, chemical, and industrial applications where durability, strength, and resistance to stress corrosion cracking are essential.
Stainless Steel 17-7 PH tubing is composed primarily of iron, with 16–18% chromium, 6–7% nickel, 0.5–0.7% copper, and small amounts of manganese, silicon, and carbon. This alloying provides excellent strength, hardness, and corrosion resistance after precipitation hardening. The combination of chromium and nickel ensures resistance to oxidation and stress corrosion cracking, while copper enhances hardness and mechanical performance. The tubing maintains high tensile and yield strength, making it suitable for demanding structural and high-stress applications.
