Stainless Steel Round Bar
Product Overview
Stainless steel bars are versatile, long-length solid products manufactured from stainless steel through hot rolling, forging, or cold drawing processes.
As fundamental raw materials for countless industrial applications, stainless steel bars offer exceptional corrosion resistance, mechanical strength, and machinability .
Our stainless steel bars are produced from prime-quality feedstock with strict control over chemical composition and mechanical properties.
The inherent chromium content (minimum 10.5%) creates a passive oxide layer on the surface, providing self-healing corrosion protection that regenerates when exposed to oxyge
Primary Applications (Aligned with Buyer Use Cases)
Our stainless steel round bars are trusted by global buyers for their adaptability to diverse project needs.
Below are the key applications, tailored to your industry-specific requirements:
| Industry | Core Use Cases | Buyer Value |
| Mechanical Engineering | Machine shafts, gears, fasteners, bolts, nuts, equipment components | High machinability and durability reduce equipment maintenance costs; precise dimensions ensure seamless assembly |
| Construction & Architecture | Structural supports, handrails, balustrades, decorative components, reinforcement bars | Corrosion resistance and strength meet building safety standards; customizable finishes enhance aesthetic appeal |
| Food & Beverage | Food processing equipment parts, conveyor shafts, mixing blades, storage tank components | Non-toxic, easy-to-clean surfaces comply with FDA/EU food contact regulations; 316L grade resists food acids |
| Chemical & Pharmaceutical | Chemical reactor components, pipeline connectors, pharmaceutical equipment parts | 316L grade resists corrosive chemicals and acids, preventing leaks and ensuring product purity |
| Automotive & Aerospace | Automotive chassis parts, engine components, aerospace fasteners | High strength and wear resistance meet strict industry standards; lightweight design reduces overall product weight |
| Decorative & Furniture | Furniture frames, decorative railings, art installations, display stands | Polished/BA finishes add premium aesthetic value; corrosion resistance ensures long-term appearance |
Core Product Specifications (Buyer-Oriented)
We offer a full range of standard and custom stainless steel round bars, strictly adhering to global standards to ensure dimensional accuracy, material consistency, and compatibility with your projects. Every specification is designed to minimize your rework costs, streamline installation, and align with your procurement budget.
| Specification | Details | Buyer-Centric Benefit |
| Material Grade | 304, 316L, 304L, 321 (equivalent to ASTM A276, A484, JIS G4303, GB/T 1220) | - 304: Cost-efficient, widely used for general applications (most popular for bulk procurement)- 316L: Molybdenum-added, superior corrosion resistance (saltwater, chemicals) for harsh environments- Global standard grades ensure smooth customs clearance and compatibility with local project requirements |
| Size Range | - Diameter: 6mm – 200mm- Length: 6m, 12m (standard); custom lengths (3m–12m) available- Tolerance: Diameter ±0.05mm, Length ±50mm | - Covers small components (e.g., fasteners, shafts) to large structural parts (e.g., machine cores)- Standard lengths simplify inventory management; custom lengths reduce cutting waste and on-site labor costs- Precise tolerance ensures perfect fitting, avoiding rework and project delays |
| Surface Treatment | 2B (Matte), BA (Mirror), Polished (400#–800#), Pickled & Passivated, Black Oxide | - 2B: Budget-friendly for industrial structural use (no extra decorative cost)- BAPolished: High-gloss finish for decorative, food, or medical applications- Pickled & Passivated: Enhances corrosion resistance for outdoor/chemical use; black oxide for aesthetic industrial parts |
| Mechanical Properties | - Tensile Strength: ≥515MPa- Yield Strength: ≥205MPa- Elongation: ≥40%- Weldable, machinable, grindable, bendable | Easy to process into custom components (cutting, drilling, threading); durable under high load and wear, extending product service life and reducing replacement costs |
| Packing & Logistics | Bundle packing (waterproof paper + steel straps) + wooden pallets; custom laser marking (grade, diameter, batch number) available; FOB/CIF/DAP/EXW terms supported | Secure packaging prevents scratches, rust, and damage during long-distance ocean shipping- Custom marking simplifies inventory tracking and brand identification- Flexible shipping terms adapt to your logistics budget and delivery timeline |
FAQs (Frequently Asked Questions for Global Buyers)
We’ve compiled the most common questions from international buyers to help you make informed procurement decisions, covering quality, customization, delivery, and compliance:
Q1: What’s the difference between 304 and 316L stainless steel round bars, and how do I choose?
A: 304 is the most cost-effective option for general applications (e.g., construction, machinery) with mild environmental exposure.
316L contains molybdenum, offering 2–3x better corrosion resistance to saltwater, chemicals, and acidic environments—ideal for marine, chemical, or food processing projects.
For standard projects, 304 delivers optimal value; for harsh environments, 316L is recommended. We provide free sample testing to help you validate performance for your specific use case.
Q2: Can you provide custom diameters, lengths, or surface treatments?
A: Yes, we specialize in custom solutions. We can customize:
- Diameter: 6mm–200mm (any size in between)
- Length: 3m–12m (non-standard lengths available)
- Surface treatments: BA mirror, 800# polished, brushed, pickled & passivated, or black oxide.
The minimum order quantity (MOQ) for custom orders is 500kg, with a lead time of 20–30 days.
Q3: What is the lead time for standard and custom orders?
A: - Standard sizes (in stock): 7–12 days from order confirmation.
- Custom orders: 20–30 days (varies by customization complexity).
For bulk orders (≥10 tons), we can expedite production to reduce lead time by 3–5 days.
Air freight is available for small sample orders (3–5 days delivery).
