DIPTI METAL INDUSTRIES
Leading AMS 5647 Stockist, AMS 5647 Supplier & AMS 5647 Exporter of 304L Stainless Steel Bar in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is the globally recognized AMS 5647 Supplier, AMS 5647 Exporter, and the foremost AMS 5647 Stockist of 304L Stainless Steel Bar, Wire, and Forging Billets in Mumbai, India. AMS 5647 dictates the rigorous aerospace and defense requirements for Type 304L Stainless Steel (UNS S30403). This highly formable austenitic stainless steel is strictly formulated with an extra-low carbon limit (0.03% max). This crucial metallurgical difference prevents the precipitation of harmful chromium carbides at the grain boundaries during heavy welding and thermal cycling. By choosing AMS 5647 over standard grades, fabricators ensure full immunity against intergranular corrosion in the heat-affected zone, entirely bypassing the need for post-weld annealing. Supplied strictly in the Solution Heat Treated condition (Condition A), this alloy is completely non-magnetic and retains exceptional toughness down to cryogenic temperatures. We are a premier AMS 5647 Distributor supplying certified Round Bars, Hex Bars, and Forgings to the global aerospace, cryogenic, and high-purity chemical sectors.

📘 Technical Specifications: The AMS 5647 Engineering Profile
AMS 5647 governs Type 304L (UNS S30403) solid products. As a highly stable austenitic stainless steel, it provides a versatile blend of corrosion resistance, weldability, and cryogenic toughness. The key to the AMS 5647 specification is the incredibly strict 0.03% max carbon limit. This low carbon profile prevents sensitization—a phenomenon where chromium reacts with carbon at high heat to form localized boundaries depleted of chromium—ensuring that welded components retain full corrosion resistance. It is strictly supplied in Condition A (Solution Annealed at 1850°F to 2050°F followed by rapid quenching).
Metallurgical Composition Limits
| Element | Target (%) | Effect |
|---|---|---|
| Carbon (C) | 0.03 max | Strictly minimized to prevent carbide precipitation during welding |
| Chromium (Cr) | 18.00 - 20.00 | Provides foundational oxidation and general corrosion resistance |
| Nickel (Ni) | 8.00 - 12.00 | Maintains austenitic structure, promotes ductility and cryogenic toughness |
| Manganese (Mn) | 2.00 max | Enhances hot workability and stability |
| Silicon (Si) | 1.00 max | Improves resistance to scaling at high temperatures |
| Phosphorus (P) | 0.045 max | Kept low to avoid brittleness |
Sulfur is restricted to 0.030% max. The primary base metal is Iron (Balance). Note: Because of its lower carbon content, 304L has slightly lower absolute yield/tensile strength compared to standard 304.
Mechanical Properties (Condition A)
| Property | Minimum Values (Solution Annealed) |
|---|---|
| Ultimate Tensile Strength | ≥ 483 MPa (70,000 psi) |
| Yield Strength (0.2%) | ≥ 172 MPa (25,000 psi) |
| Elongation in 2" | ≥ 40.0 % |
| Reduction of Area | ≥ 50.0 % |
| Hardness Limit | ≤ 201 HBW (typically max 92 HRB) |
Our AMS 5647 products are supplied Solution Heat Treated (Condition A). This guarantees a soft, highly ductile state with a uniform grain structure, making the bars fully optimized for forming, cold heading, and high-speed CNC machining.
