Hemaokang Steel (Shandong) Co., Ltd. is proud to present our Stainless Steel Bar 904L – 6mm Diameter, 1m Length, Cold Finished, fully compliant with ASTM A484 standard. As a reliable supplier with an annual export value of US$50–100 million and a team of 51–100 experienced professionals, we ensure every bar meets the highest quality benchmarks. Our 904L round bar offers exceptional corrosion resistance, making it an ideal choice for demanding environments in chemical processing, marine engineering, and offshore oil & gas applications.
This product is manufactured using an advanced cold finishing process, resulting in a smooth, bright surface with tight dimensional tolerances. The 6mm diameter and 1m length provide convenience for precision machining, prototyping, and small-scale fabrication. Whether you need a single bar for a test run or bulk quantities for production, Hemaokang Steel delivers consistent quality with ISO9001 certification.
Key Features & Technical Specifications
- Superior Corrosion Resistance: 904L stainless steel contains high levels of chromium, nickel, molybdenum, and copper, offering excellent resistance to pitting, crevice corrosion, and stress corrosion cracking in aggressive media like sulfuric acid, phosphoric acid, and chloride environments.
- Cold Finished Surface: The cold drawing process enhances surface finish (Ra ≤ 0.8 μm typical) and provides excellent dimensional accuracy, with diameter tolerance of ±0.05 mm.
- ASTM A484 Compliant: Our bars are manufactured and tested in accordance with ASTM A484/A484M, the standard specification for general requirements for stainless steel bars, billets, and forgings.
- Consistent Mechanical Properties: Typical tensile strength ≥ 490 MPa, yield strength ≥ 220 MPa, elongation ≥ 35%, hardness ≤ 255 HB – ensuring reliable performance in structural and load-bearing applications.
- Versatile Length & Diameter: 6mm diameter (0.236 inch) and 1m length (3.28 ft) are ideal for small components, shafts, fasteners, valve parts, and laboratory equipment.
- Full Traceability: Each bar comes with mill test certificates (MTC) and heat number identification, guaranteeing material traceability from melt to finished product.

Frequently Asked Questions (FAQ)
Q1: What is the difference between cold finished and hot rolled stainless steel bars?
A: Cold finished bars undergo a drawing or rolling process at room temperature, resulting in tighter tolerances, a smoother surface, and higher strength compared to hot rolled bars. Our 904L bar is cold finished to provide excellent dimensional accuracy (diameter tolerance ±0.05 mm) and a bright surface suitable for precision applications.
Q2: Can I get a sample before placing a bulk order?
A: Yes, we offer sample orders. Please contact our sales team to discuss sample availability and shipping costs. Typically, we can send a single bar or a small quantity for evaluation.
Q3: Is this bar suitable for welding or fabrication?
A: 904L stainless steel has good weldability. However, due to its high alloy content, proper welding procedures (e.g., using matching filler metal and controlling heat input) are recommended. Our bars can be used for welding, but we advise consulting a welding engineer for critical applications.
Q4: What certificates are provided with the product?
A: Each shipment includes a Mill Test Certificate (MTC) that reports chemical composition, mechanical properties, and dimensional inspection results. We also provide ISO9001 certification upon request.
Q5: Do you offer longer lengths, such as 2m or 3m?
A: Yes, we can supply custom lengths. The 1m length is a standard option, but we can produce bars up to 6m long depending on the diameter. Please inquire for specific length requirements.
Q6: What is the lead time for this product?
A: For standard stocks (6mm x 1m), lead time is typically 3–7 working days. For larger quantities or custom sizes, please allow 2–3 weeks. We can expedite orders upon request.
Q7: Is this bar compliant with EN or other international standards?
A: Our 904L bar is manufactured to ASTM A484. It can also meet EN 10088-3 or other standards if specified at the time of order. We can adjust the certification package accordingly.
Q8: How should I store the stainless steel bar to prevent surface contamination?
A: Store in a dry, clean environment away from moisture and chemicals. If the bar is not used immediately, keep it in its original packaging or wrap it with protective film to avoid scratches or rust stains.
