AMS 5637 governs corrosion-resistant 302 stainless steel bars and wire with a maximum nominal diameter or section thickness of 0.75 inch (19 mm). As a versatile austenitic stainless grade, Alloy 302 performs reliably in both annealed and cold-worked tempers. It can be easily formed, bent, machined and processed, making it one of the most cost-effective and multi-functional stainless steel grades for conventional and medium-strength industrial components. ZYTC Alloy, a professional Chinese manufacturer and supplier of premium aerospace and industrial stainless steel products, provides high-quality AMS 5637 UNS S30200 302 stainless steel bars and wires. |  |
Chemical Composition (UNS S30200)| Element | Weight % (min) | Weight % (max) |
|---|
| Chromium (Cr) | 17.0 | 19.0 | | Nickel (Ni) | 8.0 | 10.0 | | Carbon (C) | – | 0.15 | | Manganese (Mn) | – | 2.00 | | Silicon (Si) | – | 1.00 | | Phosphorus (P) | – | 0.045 | | Sulfur (S) | – | 0.030 | | Iron (Fe) | Balance | Balance |
Mechanical Properties (Cold Drawn & Stress Relieved per AMS 5637)| Property | Requirement | Unit |
|---|
| Tensile Strength (min) | 862 (125 ksi) | MPa | | Yield Strength (typical – annealed) | 275 | MPa | | Elongation (typical) | 55 | % | | Hardness (typical) | 85 | HRB | | Elastic Modulus | 193 | GPa |
Key Processing GuidelinesAnnealing: 1010 – 1121°C, rapid cool Forging/Hot Working: 1149 – 1260°C (do not forge below 927°C) Cold Working: Readily drawn, spun, upset; increases strength; may induce slight magnetism Machinability: Requires slow speeds, positive feeds, chip breakers Weldability: Use AWS E/ER308 or 312; post-weld anneal recommended for maximum corrosion resistance
ApplicationsHigh tensile shafts, bolts, nuts, gears, pinions, spindles Aircraft fasteners and aerospace hardware Automotive engine components and trim Food processing and medical equipment Spring clips, washers, and chemical industry equipment
