The martensitic precipitation-hardening stainless steel alloy used to make Stainless Steel 17-4 PH Bars contains trace amounts of niobium, manganese, silicon, and carbon in addition to chromium (15–17.5%), nickel (3–5%), and copper (3–5%). After heat treatment, these bars have exceptional mechanical qualities, such as tensile strength of up to 1100 MPa and hardness of up to 44 HRC. They provide toughness, corrosion resistance, and high yield strength over a broad temperature range. SS 17-4 PH bars are perfect for precision-engineered components because of their minimal distortion, dimensional stability, and ease of heat treatment.
