As a dedicated supplier of high-quality stainless steel products, Hemaokang Steel (Shandong) Co., Ltd. brings you the 316 Stainless Steel Round Bar for Oil & Gas Pipeline Welding Support, 20mm. Leveraging our extensive experience in the steel industry and a robust export network reaching over 50 countries, we understand the critical requirements of oil and gas pipeline applications. Our 316 round bar is engineered to provide exceptional corrosion resistance and structural integrity, making it an ideal choice for welding support and backing in demanding environments. We are committed to delivering precision and reliability that meet the exacting standards of the global energy sector.
Key Product Features & Technical Specifications
The 316 stainless steel round bar is specifically designed to withstand the harsh conditions of oil and gas pipelines, including exposure to corrosive fluids, high pressure, and extreme temperatures. Its superior performance is backed by rigorous manufacturing processes and strict quality control. Below are the core features and benefits:
- Exceptional Corrosion Resistance: The 316 grade contains molybdenum, which significantly enhances resistance to pitting and crevice corrosion in chloride environments – a common challenge in oil and gas operations.
- High Strength & Durability: With a tensile strength of approximately 515 MPa minimum, this bar offers excellent mechanical properties for supporting heavy loads during welding and pipeline assembly.
- Precision Diameter (20mm): Manufactured to tight tolerances (+/- 0.05mm) to ensure a consistent fit in welding fixtures and backing systems, minimizing gaps and ensuring uniform weld quality.
- Excellent Weldability: 316 stainless steel is readily weldable using standard techniques, and the bar's composition helps prevent hot cracking and sensitization, ensuring strong, reliable welds.
- Versatile Surface Finishes: Available in bright, black, or pickled finishes to suit different welding procedures and aesthetic requirements. Custom finishes are available upon request.
- Compliance with International Standards: Our round bars meet ASTM A276, AISI 316, and other relevant standards, ensuring compatibility with global engineering specifications.
