ASTM A276 304 Stainless Steel Bar - 10mm Diameter, Corrosion Resistant Metal Shaft
ASTM A276 304 stainless steel bars (10mm diameter) are precision-engineered corrosion-resistant metal shafts ideal for demanding industrial and mechanical applications. Made from grade 304 austenitic stainless steel, these bars combine exceptional strength, oxidation resistance, and durability in harsh environments. With a polished surface finish and tight diameter tolerance (±0.05mm), they are widely used in shafts, fasteners, machinery components, and medical equipment. The material’s low carbon content (≤0.08%) ensures weldability and resistance to intergranular corrosion, making it suitable for high-temperature or chemically aggressive settings.

3. Competitive Advantages
① Premium Material Quality
Strict control of chromium (Cr) and nickel (Ni) content ensures compliance with ASTM A276 standards, guaranteeing corrosion resistance and mechanical stability.
② Precision Manufacturing
Cold-drawn or hot-rolled processes deliver consistent diameter accuracy and surface integrity for seamless integration into assemblies.
③ Customization Options
Available in cut-to-length pieces, custom threading, or heat-treated versions (e.g., solution-annealed) for specialized projects.
④ Global Certifications
RoHS and CE compliance ensures suitability for EU markets, while ISO 9001 certification guarantees traceable quality control.
⑤ Cost Efficiency
Competitive pricing with bulk order discounts, paired with corrosion resistance, reduces long-term maintenance costs.
