Stainless Steel 17-4 PH Plates

Stainless steel 17-4 PH Plates is a martensitic, chromium-nickel stainless steel alloy. It contains 4% copper and has substantial niobium for high strength and hardness in heat-treated conditions. The chemical composition of 17-4 PH includes Carbon: 0.07%, Manganese: 1.00%, Phosphorus: 0.04%, Sulfur: 0.03%, Chromium: 15–17 %, Nickel: 3–5 %, Copper : 3–5 % and Niobium/ Columbuim: 0.15 -0.45%. This makes it suitable for use in applications that require high strength, such as aerospace, nuclear reactors, industrial equipment components and petrochemical processing plants, due to its resistance to both corrosion and oxidation at elevated temperatures ranging from 600°F up to 1400 °F (316°C – 760°C).

Stainless Steel 17-4 PH plates have a wide range of useful properties, making them an attractive choice for many applications. These include high strength, good corrosion resistance, excellent fatigue resistance, wear and abrasion resistance, easy formability, and a great balance between workability and machinery. The stainless steel provides general corrosion resistance superior to the hardenable martensitic grades and is well suited for operations involving mild acids or atmospheric exposures. Additionally, they can be provided with special finishes tailored to meet precise fabrication requirements.
