At Mitchell Stainless in Hamilton, New Zealand, we supply premium stainless steel bars designed for high-strength and corrosion-resistant applications. Our Stainless Steel 17-4 PH Bars are precipitation-hardening stainless steels offering exceptional mechanical properties, excellent corrosion resistance, and outstanding toughness. Ideal for aerospace, chemical, and high-stress industrial components, these bars maintain dimensional stability under cyclic loading and elevated temperatures. Backed by Mitchell Stainless’ commitment to quality and local expertise, 17-4 PH bars provide reliable, high-performance materials for critical applications where strength, durability, and long-term reliability are essential.
Stainless Steel 17-4 PH Bars are manufactured from a precipitation-hardening austenitic stainless steel alloy containing chromium, nickel, and copper. The alloy can be heat-treated to achieve high tensile and yield strength while maintaining excellent corrosion resistance. These bars offer superior hardness, toughness, and dimensional stability, performing reliably under repeated loading and stress. Stainless Steel 17-4 PH retains mechanical properties across a wide temperature range, making it suitable for demanding applications where high strength, fatigue resistance, and structural integrity are required.
