DIPTI METAL INDUSTRIES
Leading AMS 5645 Stockist, AMS 5645 Supplier & AMS 5645 Exporter of 321 Stainless Steel Bar in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is the globally recognized AMS 5645 Supplier, AMS 5645 Exporter, and the foremost AMS 5645 Stockist of 321 Stainless Steel Bar, Wire, and Forging Billets in Mumbai, India. AMS 5645 specifies the highly stringent aerospace requirements for Alloy 321 (UNS S32100), an austenitic stainless steel intrinsically stabilized with Titanium (Ti). This unique addition prevents the precipitation of chromium carbides at grain boundaries during welding or prolonged exposure to high temperatures (800°F - 1500°F). By using AMS 5645, aerospace and chemical engineers guarantee complete immunity to intergranular corrosion in the heat-affected zone without the need for post-weld annealing. We are a premier AMS 5645 Distributor supplying solution heat-treated Round Bars, Hex Bars, and Forgings specifically engineered for jet engine exhaust assemblies, expansion joints, and high-heat petrochemical applications worldwide.

📘 Technical Specifications: The AMS 5645 Engineering Profile
AMS 5645 specifies the chemistry and mechanical properties for Alloy 321 (UNS S32100) solid products. As an austenitic stainless steel, it is non-magnetic and highly ductile. The defining metallurgical characteristic is the addition of Titanium, which acts as a stabilizing element. The carbon in the alloy preferentially binds with titanium rather than chromium, leaving the chromium fully available to form the protective oxide layer even after heavy welding and continuous exposure to 1500°F heat.
Metallurgical Composition Limits
| Element | Target (%) | Effect |
|---|---|---|
| Chromium (Cr) | 17.00 - 19.00 | Provides foundational oxidation and general corrosion resistance |
| Nickel (Ni) | 9.00 - 12.00 | Maintains austenitic structure and promotes toughness |
| Titanium (Ti) | 5x(C) min - 0.70 max | Stabilizes the alloy; prevents carbide precipitation and intergranular attack |
| Carbon (C) | 0.08 max | Must be tied to Titanium for effective stabilization |
| Manganese (Mn) | 2.00 max | Enhances hot workability and acts as a deoxidizer |
| Silicon (Si) | 1.00 max | Promotes resistance to high-temperature oxidation |
Phosphorus and Sulfur are tightly restricted to 0.040% max and 0.030% max respectively to prevent hot shortness during welding and high-temp service. The remaining balance is Iron.
Mechanical Properties (Solution Treated)
| Property | Minimum Values (Typical) |
|---|---|
| Ultimate Tensile Strength | ≥ 517 MPa (75,000 psi) |
| Yield Strength (0.2%) | ≥ 207 MPa (30,000 psi) |
| Elongation in 2" | ≥ 40.0 % |
| Reduction of Area | ≥ 50.0 % |
| Hardness Limit | ≤ 255 HBW (Dependent on section size) |
Our AMS 5645 products are typically supplied in the Solution Heat Treated condition. This process dissolves any existing unstabilized carbides and maximizes ductility and corrosion resistance.
