DIPTI METAL INDUSTRIES
Leading AMS 6414 Stockist, AMS 6414 Supplier & AMS 6414 Exporter of 4340 VAR Steel Bar in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is a globally recognized AMS 6414 Supplier, AMS 6414 Exporter, and the foremost AMS 6414 Stockist of 4340 VAR Alloy Steel in Mumbai, India. AMS 6414 represents the pinnacle of 4340 steel, produced exclusively via Vacuum Arc Remelting (VAR) or Consumable Electrode Vacuum Melting (CEVM). This highly specialized melting process dramatically reduces non-metallic inclusions and dissolved gases, creating an ultra-clean steel that delivers immense fracture toughness and unmatched fatigue life. Capable of being heat-treated to 260,000 psi, AMS 6414 is mandated for fracture-critical aerospace components. We are a premier AMS 6414 Distributor supplying certified Bars, Billets, and Custom Forgings to mission-critical engineering sectors worldwide.

📘 Technical Specifications: The AMS 6414 Engineering Profile
AMS 6414 strictly governs the vacuum-melted version of 4340 alloy steel (UNS G43400). Its chemistry matches that of the deep-hardening nickel-chromium-molybdenum 4340 family, but the vacuum remelting process introduces incredibly strict limitations on phosphorus and sulfur. This prevents the formation of non-metallic stringers and grain boundary embrittlement. As a result, AMS 6414 can be heat-treated to higher strength levels (up to 260,000 psi) while maintaining a level of ductility, transverse toughness, and fatigue resistance that standard air-melted steel simply cannot match.
Metallurgical Composition & Purity Limits
| Element | Target (%) | Effect |
|---|---|---|
| Carbon (C) | 0.38 - 0.43 | Provides base hardness and strength |
| Nickel (Ni) | 1.65 - 2.00 | Delivers toughness and deep hardenability |
| Chromium (Cr) | 0.70 - 0.90 | Improves wear resistance and hardness |
| Molybdenum (Mo) | 0.20 - 0.30 | Maintains strength at elevated temperatures |
| Manganese (Mn) | 0.60 - 0.80 | Deoxidizer, contributes to strength |
| Silicon (Si) | 0.15 - 0.30 | General deoxidizer |
Critical Cleanliness: Sulfur and Phosphorus are strictly limited to max 0.010% (significantly lower than standard grades) due to the VAR processing.
Typical Mechanical Properties (Heat Treated)
| Property | Value | Unit |
|---|---|---|
| Ultimate Tensile Strength (UTS) | 1790 - 1930 (260,000 max) | MPa (psi) |
| Yield Strength (0.2% Offset) | ≥ 1380 (200,000) | MPa (psi) |
| Elongation in 2 inches | ≥ 10.0 | % |
| Reduction of Area | ≥ 35.0 (highly directional) | % |
| Hardness (Annealed Supply) | Max 235 | Brinell (HB) |
Our stock is typically supplied Annealed (max 235 HB) or Normalized & Tempered for easy rough machining before the final quench and temper cycle.
AMS 6414 Cross-Reference & Global Equivalents
Because AMS 6414 represents the premium, vacuum-remelted standard, it frequently cross-references with strict military and proprietary aerospace designations.
| Standard | Designation / Grade | Sector Focus |
