Types Of Stainless Steel Bars, Rods & Wires
Choose the product form that fits your part geometry, machining plan, and surface finish target. Bars, rods, and wire cover everything from heavy shafts to precision fasteners and spring-quality coils, so you can match performance, cost, and lead time.
Stainless Steel Bars
Stainless steel bar is a stable, straight stock that machines cleanly and holds tight tolerances for load-bearing parts. The higher section modulus supports strength-critical components, while bright or ground finishes help reduce post-machining rework and polishing time.
- Typical sizes: 6 mm to 500 mm dia, rounds, squares, hex
- Finishes: hot rolled, peeled and turned, bright drawn, centerless ground
- Applications: shafts, pins, flanges, valves, structural brackets
Stainless Steel Rods
Stainless steel rod is a versatile feedstock for precision components with good weldability and corrosion resistance. Consistent chemistry and dimensional control support repeatable turning, threading, and forming across small to medium diameters.
- Typical sizes: 3 mm to 120 mm dia, standard cut lengths 3 m and 6 m
- Finishes: black, bright, pickled, polished 180–600 grit
- Applications: studs, fasteners, hubs, general fabrication
Stainless Steel Wire
Stainless steel wire is a clean, uniform wire for forming, weaving, welding, and tying in corrosive environments. Available in annealed to spring tempers, it supports deep forming, stable spring rates, and reliable weldability for mesh and filler applications.
- Typical sizes: 0.2 mm to 16 mm diameter
- Finishes: bright, matte, soap-coated, spring temper, annealed
- Applications: wire mesh, springs, tying wire, welding wire, cable cores
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.
Frequently Asked Questions
1. What stainless steel grade is best for marine use?
316 or duplex grades are best for marine use due to chloride resistance. Choose a duplex where strength and SCC resistance are critical.
2. Are stainless steel bars magnetic?
Austenitic grades like 304 and 316 are generally non-magnetic in annealed condition. Cold work or ferritic/martensitic grades can show magnetism.
3. What finish should I choose for machining?
Bright drawn or centerless ground bars are best for machining because of tight tolerances and surface consistency. Free-machining 303 improves chip break and tool life.
4. Can you supply bars with third-party inspection and MTCs?
Yes, we supply EN 10204 3.1 or 3.2 MTCs with third-party inspections. All tests and markings are aligned to your project specification.
5. What is the difference between bars and rods?
Bars and rods are both long products; bars often refer to stock for machining and structural use, while rods are common in smaller diameters for fasteners and general fabrication.
6. Do you provide cut-to-length and chamfered ends?
Yes, we offer cut-to-size with chamfered or square ends. Packaging is export-ready to protect surface finish.
7. Which wire condition should I order for forming springs?
Order spring temper or work-hardened SS Wire for springs. Annealed wire is better for deep forming and subsequent heat treatment.
8. How do I estimate the weight of a stainless steel round bar?
Multiply 0.00620 by the square of the diameter in mm to get kg per metre. For exact weight, use the density from your heat’s MTC.
