DIPTI METAL INDUSTRIES
Leading AMS 5630 Stockist, AMS 5630 Supplier & AMS 5630 Exporter of 440C Stainless Steel Bar in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is the globally recognized AMS 5630 Supplier, AMS 5630 Exporter, and the foremost AMS 5630 Stockist of 440C Stainless Steel Bar, Wire, and Forging Billets in Mumbai, India. AMS 5630 dictates the rigorous aerospace requirements for Alloy 440C (UNS S44004), a high-carbon martensitic stainless steel. Renowned for attaining the highest hardness, wear resistance, and strength of all stainless steel grades after heat treatment, 440C is essential for aerospace bearings, valve components, and high-wear structural parts. Supplied in the Annealed condition to allow for complex CNC machining, AMS 5630 can be subsequently oil-quenched and tempered by the fabricator to achieve extreme hardness levels up to 58-60 HRC. We are a premier AMS 5630 Distributor supplying certified Round Bars, Hex Bars, and Forgings specifically engineered for frictionless operations and severe mechanical wear resistance worldwide.

📘 Technical Specifications: The AMS 5630 Engineering Profile
AMS 5630 specifies the chemistry and mechanical properties for Alloy 440C (UNS S44004) solid products. As a martensitic stainless steel, it relies on a very high carbon content (approximately 1.00%) combined with high chromium to form dense carbide networks when heat-treated. This metallurgical structure makes 440C extremely hard, highly magnetic, and exceptionally wear-resistant. However, because it is so hard in its final state, it must be supplied in the Annealed condition (softened) so fabricators can drill, turn, and shape the material before executing the final quench and temper.
Metallurgical Composition Limits
| Element | Target (%) | Effect |
|---|---|---|
| Carbon (C) | 0.95 - 1.20 | Highest of stainless grades; enables extreme post-heat treat hardness |
| Chromium (Cr) | 16.00 - 18.00 | Provides necessary corrosion resistance and forms hard chromium carbides |
| Molybdenum (Mo) | 0.75 max | Enhances deep hardening and provides additional pitting resistance |
| Manganese (Mn) | 1.00 max | Improves hot workability and acts as a deoxidizer |
| Silicon (Si) | 1.00 max | Aids in the steel deoxidation process |
Phosphorus and Sulfur are tightly restricted to 0.040% max and 0.030% max respectively to maintain fatigue strength. The remaining balance is Iron. 440C is strongly magnetic in all conditions.
Mechanical Properties (Annealed & Capable Of)
| Property | Supplied Annealed | Capable Of (Hardened) |
|---|---|---|
| Hardness Limit | ≤ 269 HBW (~28 HRC) | 58 - 60 HRC |
| Ultimate Tensile Strength | ~ 758 MPa (110,000 psi) | ≥ 1896 MPa (275,000 psi) |
| Yield Strength (0.2%) | ~ 448 MPa (65,000 psi) | ≥ 1310 MPa (190,000 psi) |
| Elongation in 2" | ≥ 14.0 % | ~ 2.0 % |
Our AMS 5630 products are explicitly supplied in the Annealed condition (max 269 HBW) for machinability. The "Capable Of" properties are achieved when the fabricator heats the component to ~1900°F (1038°C), quenches in warm oil, and tempers.
