DIPTI METAL INDUSTRIES
Leading AMS 5640 Stockist, AMS 5640 Supplier & AMS 5640 Exporter of 303 Stainless Steel Bar in Mumbai, India
Dipti Metal Industries (A KMR Group Company) is the globally recognized AMS 5640 Supplier, AMS 5640 Exporter, and the foremost AMS 5640 Stockist of 303 Free-Machining Stainless Steel Bar, Wire, and Forging Billets in Mumbai, India. AMS 5640 dictates the rigorous aerospace requirements for Alloy 303 (UNS S30300). Designed explicitly for heavy, high-speed automated machining, Type 303 incorporates a crucial addition of Sulfur (Type 1) which acts as a built-in lubricant and chip-breaker. This prevents the long, stringy chips typically associated with austenitic stainless steels, allowing CNC Swiss lathes and multi-spindle screw machines to run at maximum speeds with drastically reduced tool wear. By specifying AMS 5640, manufacturers of aerospace fasteners, bushings, and highly intricate shafts achieve exceptional surface finishes and tight tolerances. We are a premier AMS 5640 Distributor supplying certified Cold Finished Round Bars and Precision Hex Bars engineered for unparalleled production efficiency worldwide.

As a leading AMS 5640 Supplier in Mumbai, Dipti Metal Industries maintains a highly specialized supply chain dedicated to free-machining aerospace alloys. We source our AMS 5640 exclusively from Certified Tier-1 Mills utilizing precise melting and inclusion-control practices. This ensures the sulfur inclusions responsible for chip-breaking are uniformly distributed, preventing hard spots that can shatter delicate CNC tooling during unmanned "lights-out" manufacturing.

📘 Technical Specifications: The AMS 5640 Engineering Profile
AMS 5640 specifies the chemistry and mechanical properties for Alloy 303 (UNS S30300) solid products. It is the most readily machinable of all the austenitic grades of stainless steel. The machinability rating of 303 is approximately 78% compared to standard B1112 free-machining carbon steel. The primary modifier is Sulfur (Type 1) which forms manganese sulfide inclusions. These inclusions act as stress raisers during the cutting action, allowing the chip to break cleanly and reducing friction on the cutting tool face. Due to this chemistry, AMS 5640 is non-magnetic but has a slightly lower corrosion resistance than 304 and is strictly not recommended for welding.
Metallurgical Composition Limits (Type 1)
| Element | Target (%) | Effect |
|---|---|---|
| Chromium (Cr) | 17.00 - 19.00 | Provides foundational oxidation and general corrosion resistance |
| Nickel (Ni) | 8.00 - 10.00 | Maintains austenitic structure and promotes toughness |
| Sulfur (S) | 0.15 min | Crucial addition; forms sulfides to break chips and lubricate cutting tools |
| Carbon (C) | 0.15 max | Maintains structural integrity |
| Manganese (Mn) | 2.00 max | Binds with sulfur to form manganese sulfides (MnS) |
| Phosphorus (P) | 0.20 max | Slightly elevated to further assist machinability |
Molybdenum (Mo) is permitted up to 0.60% max. The remaining balance is Iron. Type 2 (Selenium bearing) is rarely specified in modern manufacturing due to environmental and health restrictions regarding Selenium.
Mechanical Properties (Typical Cold Finished)
| Property | Typical Minimum Values |
|---|---|
| Ultimate Tensile Strength | ≥ 620 MPa (90,000 psi) |
| Yield Strength (0.2%) | ≥ 310 MPa (45,000 psi) |
| Elongation in 2" | ≥ 35.0 % |
| Reduction of Area | ≥ 40.0 % |
| Hardness Limit | ≤ 228 HBW (Dependent on cold work) |
Our AMS 5640 products are commonly supplied in the Cold Finished or Condition A (Annealed) state. Cold finishing slightly increases tensile and yield strength while dramatically improving dimensional tolerances essential for high-speed collet chucks.
