DIPTI METAL INDUSTRIES
Leading AMS 5659 Stockist, AMS 5659 Supplier & AMS 5659 Exporter of 15-5 PH Stainless Steel Bar in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is the globally recognized AMS 5659 Supplier, AMS 5659 Exporter, and the foremost AMS 5659 Stockist of 15-5 PH Stainless Steel Bar, Wire, and Forging Billets in Mumbai, India. AMS 5659 dictates the rigorous aerospace requirements for Alloy 15-5 PH (UNS S15500). This martensitic precipitation-hardening stainless steel is renowned for providing high strength, excellent corrosion resistance, and remarkably superior transverse toughness compared to standard 17-4 PH. To achieve this, AMS 5659 mandates Consumable Electrode Remelting (VAR or ESR), which severely limits inclusion content and prevents the formation of delta ferrite stringers. Supplied predominantly in Condition A (Solution Treated) for optimal machinability, 15-5 PH can then be easily age-hardened to achieve tensile strengths up to 190 ksi. We are a premier AMS 5659 Distributor supplying certified Round Bars, Hex Bars, and Forgings to the global aerospace, petrochemical, and high-performance engineering sectors.

📘 Technical Specifications: The AMS 5659 Engineering Profile
AMS 5659 governs Alloy 15-5 PH (UNS S15500) long products and forgings, representing a martensitic precipitation-hardening stainless steel engineered for structural integrity. The defining feature of AMS 5659 is the strict requirement for consumable electrode remelting, which suppresses the formation of delta ferrite stringers, ensuring isotropic (uniform) mechanical properties in both longitudinal and transverse directions. It is typically supplied in Condition A (Solution Treated) and can be easily age-hardened at various temperatures to achieve the desired balance of strength and toughness.
Metallurgical Composition Limits
| Element | Target (%) | Effect |
|---|---|---|
| Chromium (Cr) | 14.00 - 15.50 | Provides excellent corrosion resistance |
| Nickel (Ni) | 3.50 - 5.50 | Stabilizes structure and contributes to toughness |
| Copper (Cu) | 2.50 - 4.50 | Primary element forming copper-rich precipitates for hardening |
| Columbium (Cb) + Tantalum (Ta) | 0.15 - 0.45 | Refines grain size and prevents intergranular corrosion |
| Carbon (C) | 0.07 max | Kept very low to prevent carbide precipitation and improve ductility |
| Manganese (Mn) | 1.00 max | Improves hot workability |
| Silicon (Si) | 1.00 max | Acts as a deoxidizer during melting |
Phosphorus and Sulfur are restricted to 0.040% max and 0.030% max, respectively. Iron is the balance. The composition is strictly balanced to minimize delta ferrite formation.
Mechanical Properties (Condition A vs. H900)
| Property | Condition A (Typical) | Condition H900 (Min limits) |
|---|---|---|
| Ultimate Tensile Strength | ~ 1034 MPa (150,000 psi) | ≥ 1310 MPa (190,000 psi) |
| Yield Strength (0.2%) | ~ 758 MPa (110,000 psi) | ≥ 1172 MPa (170,000 psi) |
| Elongation in 2" | ≥ 8.0 % | ≥ 10.0 % (Longitudinal) |
| Reduction of Area | N/A | ≥ 35.0 % (Longitudinal) |
| Hardness Limit | ≤ 363 HBW | 40 - 47 HRC |
Our AMS 5659 products are typically supplied Solution Treated (Condition A), allowing for straightforward machining prior to the customer's age-hardening furnace cycle (e.g., H900, H1025, H1150).
