The Stainless Steel 15-5 PH Bars from Ed Stainless are martensitic precipitation-hardening stainless steels, primarily made up of around 15% chromium and 5% nickel, along with small amounts of copper and other elements. These bars are known for their impressive mechanical strength, hardness (reaching up to HRC 40–45), and excellent corrosion resistance. They can be heat-treated to various conditions, ranging from H900 to H1150, allowing for fine-tuning of their performance characteristics. The alloy maintains good toughness even under high-strength conditions and offers superior transverse properties compared to 17-4 PH, thanks to its finer microstructure. Ed Stainless guarantees consistency and reliability across all their 15-5 PH Bars, making them ideal for demanding applications.
