AISI 347 Stainless Steel Round Bars:

AISI 347 Stainless Steel is stabilized austenitic stainless steel with chromium and nickel, enriched with columbium and tantalum. This alloy is specifically designed to resist chromium carbide formation, ensuring stability against corrosion. Columbium-tantalum carbides precipitate within the grains, preventing formation at grain boundaries.

We subject our stainless steel round bars to rigorous testing before supply and export to identify and rectify any manufacturing defects. Tests include tensile testing, flattening-flare testing, chemical and mechanical testing, hydrostatic testing, impact testing, ultrasonic testing, and hardness testing.

To address any doubts or concerns, we provide comprehensive documentation and certificates along with our AISI 347 Stainless Steel Round Bars. These documents, including reports per EN10204/3.1, machinery reports, third-party test reports, and IBR test certificates, assure our customers of the quality and integrity of our products.

Difference between 304 and 347 Stainless Steel Round Bars:

347 stainless steel round bars offer superior corrosion resistance compared to 304 stainless steel, owing to their higher chromium content. While 347 stainless steel is tougher and stronger than 304, it is slightly less machinable and weldable. Additionally, 347 stainless steel exhibits better oxidation resistance at higher temperatures, making it suitable for applications requiring enhanced protection against environmental elements.

Welding 347 Stainless Steel Bar:

Welding 347 stainless steel bars requires specialized techniques and tools due to their high chromium content and carbon levels. Shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW), and plasma arc welding (PAW) are common methods used for welding 347 stainless steel bars. Proper technique and equipment selection are essential to ensure strong and visually appealing welds.
