Stainless Steel Bars, Rods
Choose your SS round bar grade by matching corrosion resistance, strength, machinability, and temperature limits to the job. From 304/316 for general and marine use, 303 for fast machining, 310S for heat, to 17-4PH and Duplex 2205 for high strength and chloride service, each grade offers a clear advantage.
| Grade | UNS | Key traits | Typical uses |
|---|---|---|---|
| 304 / 304L | S30400 / S30403 | General corrosion resistance, good formability | Shafts, fixtures, food equipment |
| 316 / 316L | S31600 / S31603 | Mo for chloride resistance | Marine hardware, pumps, fasteners |
| 303 | S30300 | Sulfur for free machining | Screws, bolts, turned parts |
| 321 | S32100 | Ti stabilized for welds at temp | Exhaust parts, manifolds |
| 310S | S31008 | High temp oxidation resistance | Furnace jigs, heat treatment tooling |
| 410 | S41000 | Martensitic, hardenable | Wear parts, turbine components |
| 420 | S42000 | Higher C for hardness | Cutlery, dies, gauges |
| 431 | S43100 | Toughness with strength | Prop shafts, bolts |
| 17-4PH | S17400 | Precipitation hardening, high strength | Aerospace, precision parts |
| 2205 Duplex | S32205/S31803 | High strength, chloride SCC resistance | Seawater service, pressure parts |
| 904L | N08904 | Super-austenitic, strong acids | Chemical process equipment |
Mechanical Properties of Stainless Steel Bars, Rods & Wires
Select grades by matching tensile and yield strength to load cases, then check elongation for formability. Hardness limits help plan machining, grinding, and post-process finishing. Verify the actual values for your size and condition on the MTC.
| Grade | Tensile strength (MPa) | Yield strength (MPa) | Elongation (%) | Hardness |
|---|---|---|---|---|
| 304L | ≥485 | ≥170 | ≥40 | ≤92 HRB |
| 316L | ≥485 | ≥170 | ≥40 | ≤95 HRB |
| 303 | ~620 | ~240 | ≥35 | ≤100 HRB |
| 310S | ≥515 | ≥205 | ≥40 | ≤95 HRB |
| 410 (annealed) | ≥450 | ≥205 | ≥20 | ≤22 HRC |
| 2205 Duplex | ≥620 | ≥450 | ≥25 | ≤290 HB |
Applications of Stainless Steel Bars, Rods & Wires
Stainless steel bars, rods, and wire serve critical roles across construction, marine, industrial machinery, oil and gas, chemical processing, food and pharma, power, automotive, and water treatment. Bars take on load-bearing and heat-exposed parts, rods suit fasteners and general fabrication, and wire is ideal for rigging, mesh, conveyors, and welding. Choose 316L or duplex for chlorides, 17-4PH for high strength, and 310S for high temperature to keep equipment reliable and low maintenance.
- Construction: high tensile SS Bars for load-bearing members; corrosion resistance for exposed fittings; weld-friendly SS Rods for faster site work.
- Marine: chloride-resistant SS Rods for docks and fixtures; SS Wire for rigging and lifelines; low maintenance for coastal climates.
- Industrial machinery: wear-resistant SS Bars for shafts; dimensional stability for precision turned parts; reliable performance under vibration.
- Oil and gas: duplex SS Bars for seawater service; 316/316L for sour-adjacent utilities; traceable supply for audits.
- Chemical processing: molybdenum-bearing SS Rods for acids; smooth, cleanable surfaces for hygienic lines; documented testing for compliance.
- Food and pharma: non-reactive SS Wire for conveyors and screens; polished SS Rods for sanitary fittings; easy cleaning for HACCP lines.
- Power and energy: heat-resistant SS Bars for high-temp fixtures; creep-capable alloys for plant hardware; tight tolerances for turbine auxiliaries.
- Automotive: free-machining 303 for fasteners; 17-4PH for high strength parts; bright bars for visual components.
- Water treatment: 316L SS Rods for clarifiers; SS Wire mesh for filtration; corrosion resistance for chlorinated media.
- General fabrication: multipurpose SS Bars for brackets and frames; consistent stock for repeatability; ready-to-weld supply.
