What is 17-4 PH Stainless Steel?
17-4 PH stainless steel is a precipitation-hardening martensitic stainless steel known for its high strength, excellent toughness, and corrosion resistance. It's a widely used alloy in demanding applications across aerospace, medical, chemical processing, and food industries. The "17-4 PH" designation refers to its approximate composition: about 17% chromium and 4% nickel. The PH signifies its ability to be heat-treated to achieve very high strength levels through a precipitation hardening process, unlike some other stainless steels.
This alloy offers a unique combination of properties, making it a preferred choice when high performance under challenging conditions is critical. Its ability to achieve high strength without sacrificing ductility or corrosion resistance is a key differentiator. Understanding its weight and density is crucial for structural calculations, material selection, and cost estimations in various engineering projects.

Key Factors That Affect 17-4 PH Results
While the core calculation is straightforward, several factors can influence the perceived or actual weight and the material's suitability. Our calculator uses standard values, but real-world considerations are important.
- Dimensional Accuracy: The precision of the supplied 17-4 PH material's dimensions is critical. Variations from the nominal values (e.g., diameter, thickness) will directly impact the calculated volume and, consequently, the weight. Tight tolerances are crucial for high-precision applications.
- Machining Allowance: Raw 17-4 PH stock is often oversized to allow for machining. The calculator provides the weight of the nominal dimensions, but the actual finished part will weigh less after machining. Factor in this material removal for accurate finished weight.
- Heat Treatment Condition: While the density of 17-4 PH remains relatively constant across different heat treatment conditions (like Condition A, H900, H1025, etc.), other properties like strength and hardness change significantly. The calculator assumes standard density regardless of condition.
- Surface Finish: Minor variations in surface roughness typically have a negligible impact on the overall weight calculation for larger components. However, for very small or intricate parts, surface texture could theoretically contribute minuscule weight differences.
- Presence of Internal Defects: Porosity or voids within the material, though uncommon in quality 17-4 PH, would reduce the actual weight compared to the calculated value. Our calculator assumes a solid, defect-free material.
- Material Grade Variations: Although 17-4 PH is a standardized grade, slight variations in composition between different manufacturers might lead to minuscule differences in density. The calculator uses the industry-standard 7.75 g/cm³.
- Temperature Effects: Density has a slight thermal expansion coefficient. While negligible at typical operating temperatures, extreme temperature variations could theoretically alter density and thus weight slightly. This calculator operates at standard room temperature assumptions.
Frequently Asked Questions (FAQ)
Q1: What is the standard density of 17-4 PH stainless steel used for weight calculation?
A1: The standard density for 17-4 PH stainless steel is approximately 7.75 grams per cubic centimeter (g/cm³) or 7750 kilograms per cubic meter (kg/m³). Our calculator uses this value.
Q2: Does the heat treatment condition affect the weight of 17-4 PH?
A2: No, the heat treatment process (like aging to achieve different hardness levels such as H900, H1025, etc.) primarily affects the mechanical properties (strength, hardness) and does not significantly change the density or weight of the 17-4 PH material itself.
Q3: Can I use this calculator for hollow parts or custom shapes?
A3: The calculator includes options for common shapes like bars, sheets, and tubes. For complex hollow sections or truly custom geometries, you would need to calculate the volume of the specific shape manually or use specialized CAD software before applying the density for weight calculation.
Q4: What units should I use for dimensions?
A4: The calculator is designed to accept dimensions in millimeters (mm). The output weight will be in kilograms (kg).
Q5: How accurate is the weight calculation?
A5: The accuracy depends on the precision of your input dimensions and the consistency of the material's density. For standard 17-4 PH and accurate measurements, the calculation is highly accurate for estimating raw material weight.
Q6: What is 'Unit Weight' in the results?
A6: 'Unit Weight' (typically displayed as kg/m) represents the weight of the material per linear meter. This is particularly useful for bars and tubes, helping estimate costs for standard lengths of stock material.
Q7: Can this calculator be used for other stainless steel grades?
A7: No, this calculator is specifically tuned for the density of 17-4 PH stainless steel (7.75 g/cm³). Other stainless steel grades (like 304 or 316) have different densities and would require a different calculator or a manual adjustment of the density value.
Q8: What does 'PH' stand for in 17-4 PH?
A8: 'PH' stands for Precipitation Hardening. This indicates that the alloy can be heat-treated to achieve very high strength levels by forming fine precipitates within the metal matrix.
