Industry Pain Points
In the production and processing of stainless steel, inaccurate control of ferrite content can lead to non-compliance of material properties, such as hot cracking during welding, which affects the material's corrosion resistance and processing performance. Therefore, accurate determination of ferrite content is crucial for ensuring product quality.
