DIPTI METAL INDUSTRIES
Leading AMS 5644 Stockist, AMS 5644 Supplier & AMS 5644 Exporter of 17-7 PH Stainless Steel Bar in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is the globally recognized AMS 5644 Supplier, AMS 5644 Exporter, and the foremost AMS 5644 Stockist of 17-7 PH Stainless Steel Bar, Wire, and Forging Billets in Mumbai, India. AMS 5644 dictates the rigorous aerospace requirements for Alloy 17-7 PH (UNS S17700), a highly advanced semi-austenitic precipitation-hardening stainless steel. In its supplied Solution Heat Treated condition (Condition A), 17-7 PH is easily formed, drawn, and machined. Following fabrication, components undergo a specialized aging process (such as TH1050 or RH950) where Aluminum and Nickel react to form intermetallic precipitates, achieving extraordinary tensile strengths exceeding 200 ksi alongside excellent fatigue life and corrosion resistance. By using AMS 5644, aerospace engineers secure the perfect balance of pre-fabrication ductility and massive post-treatment strength. We are a premier AMS 5644 Distributor supplying certified Round Bars, Hex Bars, and Forgings specifically engineered for high-stress aerospace springs, flexures, and structural hardware worldwide.

📘 Technical Specifications: The AMS 5644 Engineering Profile
AMS 5644 specifies the chemistry and mechanical properties for Alloy 17-7 PH (UNS S17700) solid products. As a semi-austenitic precipitation-hardening stainless steel, it is highly ductile in its Condition A (Solution Treated) state. Following complex forming operations, fabricators utilize specific heat treatment cycles (Condition TH1050, RH950, or CH900) to precipitate Aluminum-Nickel compounds within the microstructure. This transforms the steel into a martensitic phase, granting it immense yield and tensile strength while minimizing dimensional distortion.
Metallurgical Composition Limits
| Element | Target (%) | Effect |
|---|---|---|
| Chromium (Cr) | 16.00 - 18.00 | Provides foundational oxidation and general corrosion resistance |
| Nickel (Ni) | 6.50 - 7.75 | Maintains austenite stability; reacts with Aluminum to harden alloy |
| Aluminum (Al) | 0.75 - 1.50 | Primary hardening agent forming strengthening intermetallic precipitates |
| Carbon (C) | 0.09 max | Maintains toughness and controls martensite formation |
| Manganese (Mn) | 1.00 max | Enhances hot workability and acts as a deoxidizer |
| Silicon (Si) | 1.00 max | Improves resistance to scaling at high temperatures |
Phosphorus and Sulfur are tightly restricted to 0.040% max and 0.030% max respectively to prevent brittleness. The remaining balance is Iron.
Mechanical Properties (Condition A & Capable Of)
| Property | Condition A (Supplied) | Condition TH1050 (Aged) |
|---|---|---|
| Ultimate Tensile Strength | ≤ 896 MPa (130,000 psi) | ≥ 1172 MPa (170,000 psi) |
| Yield Strength (0.2%) | ~ 275 MPa (40,000 psi) | ≥ 965 MPa (140,000 psi) |
| Elongation in 2" | ≥ 20.0 % | ≥ 6.0 % |
| Hardness Limit | ≤ 207 HBW (~92 HRB) | 38 - 44 HRC |
Our AMS 5644 products are typically supplied in Condition A (Solution Treated) for maximum pre-fabrication ductility. Note: Aging to Condition RH950 can yield ultimate tensile strengths exceeding 1448 MPa (210,000 psi).
