DIPTI METAL INDUSTRIES
Leading AMS 5653 Stockist, AMS 5653 Supplier & AMS 5653 Exporter of 347 Stainless Steel Bar in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is the globally recognized AMS 5653 Supplier, AMS 5653 Exporter, and the foremost AMS 5653 Stockist of 347 Stainless Steel Bar, Wire, and Forging Billets in Mumbai, India. AMS 5653 specifies the highly stringent aerospace requirements for Alloy 347 (UNS S34700), an austenitic stainless steel intrinsically stabilized with Niobium (Columbium) and Tantalum. 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 5653, 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 5653 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 5653 Engineering Profile
AMS 5653 specifies the chemistry and mechanical properties for Alloy 347 (UNS S34700) solid products. As an austenitic stainless steel, it is non-magnetic and highly ductile. The defining metallurgical characteristic is the addition of Columbium (Niobium) and Tantalum, which act as stabilizing elements. The carbon in the alloy preferentially binds with these stabilizers 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 - 13.00 | Maintains austenitic structure and promotes toughness |
| Columbium (Nb) + Ta | 10x(C) min - 1.10 max | Stabilizes the alloy; prevents carbide precipitation and intergranular attack |
| Carbon (C) | 0.08 max | Must be kept low and tied to Niobium 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 0.030% max each 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 5653 products are typically supplied in the Solution Heat Treated condition. This process dissolves any existing carbides and maximizes ductility and corrosion resistance.
