Description	SUY-1 is a mild steel with extremely low carbon and low impurities. This grade is specified in JIS C2504 "Soft Magnetic Irons" and is commonly referred to as "Pure Iron". SUY grades are classified from SUY-0 to SUY-3 according to their magnetic properties. :contentReference[oaicite:0]{index=0} Due to its very low carbon and impurity content, SUY-1 offers excellent drawability and soft magnetic characteristics, making it widely used in motor components, electromagnetic parts, and magnetic shielding applications. Its magnetic properties, such as magnetic flux density and coercive force, can be further enhanced through magnetic annealing after cold working. :contentReference[oaicite:1]{index=1} Difference between SUYP and SUYB The suffix indicates the product shape: P = Plate / Sheet / Strip (e.g., SUYP-1) B = Bar / Wire (e.g., SUYB-1) Example: SUYP-1 means SUY-1 supplied in plate, sheet, or strip form. :contentReference[oaicite:2]{index=2}
