At Mitchell Stainless in Hamilton, New Zealand, we supply high-performance stainless steel sheets and plates engineered for strength, corrosion resistance, and durability. Our Stainless Steel 17-4 PH Sheets and Plates are precipitation-hardening stainless steel, offering excellent tensile strength, hardness, and mechanical performance. Ideal for aerospace, chemical, petrochemical, and high-performance industrial applications, these sheets and plates provide reliable structural integrity and long-term durability. Supported by Mitchell Stainless’ commitment to quality and local expertise, 17-4 PH Sheets and Plates deliver corrosion-resistant, high-strength solutions for demanding industrial, structural, and engineering projects.
Stainless Steel 17-4 PH Sheets and Plates are manufactured from a precipitation-hardening austenitic-ferritic stainless steel alloy containing chromium, nickel, and copper. This composition allows heat treatment to achieve superior tensile and yield strength while maintaining excellent corrosion resistance. The material offers high hardness, toughness, and dimensional stability under stress, performing reliably in high-load and high-stress applications. Stainless Steel 17-4 PH maintains mechanical integrity across a wide temperature range, making it suitable for aerospace, chemical, and industrial projects where strong, durable, and corrosion-resistant stainless steel components are required.
