DIPTI METAL INDUSTRIES
Leading AMS 5639 Stockist, AMS 5639 Supplier & AMS 5639 Exporter of 304 Stainless Steel Bar in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is the globally recognized AMS 5639 Supplier, AMS 5639 Exporter, and the foremost AMS 5639 Stockist of 304 Stainless Steel Bar, Wire, and Forging Billets in Mumbai, India. AMS 5639 outlines the rigorous aerospace requirements for Type 304, the most widely utilized "18-8" austenitic stainless steel globally. Supplied in the solution heat-treated (annealed) condition, it delivers an optimal blend of moderate structural strength, exceptional multi-environment corrosion resistance, and superb machining characteristics. Because it remains non-magnetic in the annealed state and retains immense toughness at cryogenic temperatures, we are a premier AMS 5639 Distributor supplying certified Round Bars, Hex Bars, and Machined Forgings for highly critical aerospace fittings, fasteners, and fluid-handling systems worldwide.

📘 Technical Specifications: The AMS 5639 Engineering Profile
AMS 5639 sets the strict dimensional, mechanical, and chemical boundaries for 304 Stainless Steel (UNS S30400) primarily in bar, forging, and mechanical tubing forms. Because it is an austenitic alloy, it provides excellent resistance to atmospheric corrosion, sterilizing solutions, and numerous organic/inorganic chemicals. While standard 304 is highly weldable, it is susceptible to carbide precipitation (sensitization) if subjected to heavy welding. For applications requiring intensive welding, AMS 5647 (304L) is typically recommended.
Metallurgical Composition Limits
| Element | Target (%) | Effect |
|---|---|---|
| Carbon (C) | 0.08 max | Maintains structural strength without severe embrittlement |
| Chromium (Cr) | 18.00 - 20.00 | Provides critical corrosion and oxidation resistance |
| Nickel (Ni) | 8.00 - 10.50 | Stabilizes the austenitic structure and enhances ductility |
| Manganese (Mn) | 2.00 max | Improves hot workability and serves as a deoxidizer |
| Silicon (Si) | 1.00 max | Enhances resistance to high-temperature oxidation |
| Phosphorus (P) | 0.045 max | Kept low to prevent embrittlement |
| Sulfur (S) | 0.030 max | Maintained at low levels for better forming and welding |
The austenitic structure ensures the material is virtually non-magnetic in the annealed condition. Slight magnetism may occur after severe cold working.
Mechanical Properties (Annealed Condition)
| Property | Value | Unit |
|---|---|---|
| Ultimate Tensile Strength (UTS) | ≥ 515 (75,000) | MPa (psi) |
| Yield Strength (0.2% Offset) | ≥ 205 (30,000) | MPa (psi) |
| Elongation in 2" (50mm) | ≥ 30.0 - 40.0 | % |
| Reduction of Area | ≥ 40.0 | % |
| Maximum Hardness | ≤ 288 HB / 90 HRB | Brinell / Rockwell B |
Our AMS 5639 products are strictly supplied Solution Heat Treated (Annealed). Type 304 cannot be hardened by thermal treatment; strength can only be increased via cold working.
