摘要

Due to its long-term cost effectiveness and inherent corrosion resistance, 300-series stainless steel (also called austenitic) has become a staple across the pipeline and gas industries. However, TIG welding this pipe poses distinct challenges, as it is prone to carbide precipitation, which results when chrome and carbon are drawn out of the weld, causing it to turn black. It is also a poor conductor of heat, making it susceptible to distortion.
